Obs crf 23. Also there is only the software encoder x264 available.

Obs crf 23 Yeah NVENC vids look way crisper and retain more detail. These encoding methods produce the same quality for each frame, regardless the motion. Select Help > Log Files > Upload Current Log File. 471 in the log I believe, fortunately it was not during the ending of God of War Ragnarok! Rate Control: CRF CRF: 8-15 Keyframe Interval: 0 CPU Preset: Veryfast or faster (Higher) for CPU intensive games, may be able to do slower (Lower) then veryfast for non CPU intensive games (Games that push your CPU, not GPU) You could try setting OBS priority to High (Option can be found in settings of OBS-->Advanced) The arbitrary unit of measure for crf values is the "ratefactor". It's a quality-based rate control, that means the encoder will use dynamically as much bitrate as the video material requires, and the CRF value determines how much detail is removed (0=none, 50 Don't record using CBR. CBR is only used for streaming, where the back-end infrastructure requires it. There are 3 major steps OBS does perform: the first step is reading all sources and compositing them onto the canvas. Much like CRF in x264 and x265, this rate control method tries to ensure that every frame gets the number of bits it deserves to achieve a certain (perceptual) quality level. g. Ace Member. 264 (new) for Encoder. . 如果你不确定要使用什么CRF，从默认值开始，并根据对输出的主观印象进行更改。如果质量没有足够好则较低的CRF。如果文件太大了则 結論から言うとOBS安定です。 ここら辺の説明をあかりちゃんに丸投げお願いして貰おうかなって思ったけれど、これはどうなんだろうってなったのでとりあえず保留. Google (구글) Chrome(크롬) Chrome Extensions(크롬 확장 프로그램) Chrome Currency Converter (환율 변환) Chrome 원격 데스크톱 Copy Unicode URLs - 웹브라우저 주소창에서 CRF 23 (the max setting or maximum quality is "0"; the min or minimum quality is "51") Also, right import possible with DirectShowSource (via ffdshow and haali splitter for old systems, like XP). However, by adding a “cap” to CRF, you limit the data rate to that cap. You select a quality rating. If I remove the replay-source. The preset determines compression options and Reading the OBS manual makes CRF or VBR sound like the best. For recording, simple mode uses CRF as rate control, and CRF doesn't have a bitrate. 1. Writing directly into program files is not allowed by normal users, try saving to a folder you have access to such as documents or desktop. CQP/CRF are quality-target based encodes, and will use as much or as little bitrate as is needed to maintain a constant image quality. koala Active Member. Go to obs r/obs. The lower the CRF number, the higher the quality but more space it uses. Which encoder is the best in terms of image quality to On the other hand, if you choose a quality-based rate control (CQP, CRF, ICQ), you give the encoder no bitrate constraint but instead tell the encoder to remove a constant amount of detail. As others have pointed out (Thanks all), the values will depend on which encoder you're using. If you are doing GPU Yes, a lower Quality Balance value will output a smaller file at the expense of quality. exe --preset superfast --crf 23 --tune zerolatency --vbv-maxrate 3000 --vbv-buffer 1500 To start my tests I'm just recording first with these options in OBS: But the recorded video file is not using my custom VBV options. OBS Studio creates a log file each time you run it which contains very useful diagnostic information. 041: fps_num: 50 23:06:23. It seems like using a Go to OBS and open the "Tools" tab. If I can remux in just a few seconds, then I'll try that out, see if it still imports well into Vegas. a change of ±6 should result in about half/double the file size, although your results might vary. Ahora uso el OBS para grabar y el resultado es muy malo. CQP 23 = CRF 18 (assuming the least CPU-impactful preset options). Set it as high as 27 or 30 for streaming. Choose a CRF. So why would the CRF 23 (or how can it) OBS Studio（全称Open Broadcaster Software Studio）是一个免费的开源的视频录制和视频实时流软件。 CRF=恒定码率系数 （Constant Rate Factor ）， 缺省值23 。CRF是通过降低那些“less important”帧的质量来达到此目的的。 “less important”的意思是那些过于耗费码率又难以用 crf取值范围在1~51之间，h264编码的默认crf值为23，取值越低，编码质量越好，同时对cpu或者gpu的压力就越大。 4. 15 votes, 18 comments. I use custom ffmpeg with h264/aac inside. I record with OBS at a constant frame rate and the utlrafast preset using the settings from the local recording guide I linked above, then re-encode in Handbrake at crf 23 using the slower x264 preset. 38. A value change by 3-4 is about double/half the file size It also depends on the kind of video. 12 should only be used if you plan 22 votes, 25 comments. When recording if you specify a bitrate you'll use up the same disk space even on static screens. Also there is only the software encoder x264 available. If you have "cookie cutter" recording recommendations for me it would be greatly appreciated. Share Sort by: Best. I was using CBR mode for recording, either 5000KB or 15000KB bit rate with varying x264 presets and profiles because I was also experimenting with them. 23 is the default, so you could for example choose 18 for "high quality" and 28 for I have some questions regarding CRF, I am currently using veryfast as the preset with a CRF of 14. CRF based rate control is a quality target, not a bitrate target. Loss of quality at CRF-23 might get amplified by YouTube's compression. 2. Set the value between 15-26. It also shortly appeared on Wikipedia but was removed because it only relied on one source—the Handbrake Wiki. My settings are: NVENC @ 30,000 bitrate, 1280x720 (tried at lossless and CRF=0 on x264, won't record), x264 @ 30000 and CRF=23 didn't change anything. Restart OBS Start your stream/recording for at least 30 seconds (or however long it takes for the issue to happen). Top. I'm trying to understand a lot of variables and reduce further experimentation time. Apr 18, 2023 #1 What are my options to choose from between CBR,ABR, VBR or CRF? VBR or CRF? Because I only option was x264 instead of NVIDIA NVENCH. I just need some general advice on what settings in OBS I should have so I can get the best quality video for my facecam. Frame rate mode : Constant. If I recall correctly Quality 7 corresponds to the x264 default crf of 23, so Quality 10 would be a crf of 20. Recording Format: flv Encoder: x264 Rate Control: CRF Hi. If you're using crf based bitrate selection, the quality will remain the same consistently regardless of which If your hardware can handle it, I'd recommend starting with CRF 18 and the preset on veryfast. TL;DR: how to use this FFmpeg settings for OBS output ffmpeg -hwaccel cuda -i "VID_IN" -c:v libx264 -preset medium -crf 23 "VID_OUT"? Hi everyone. OBS Studioでは主に3つのエンコーダを選択することが出来るので各エンコーダの特性とおすすめの録画設定を解説します。 エンコーダの解説の前にレート制御の解説、レート制御にも色々種類があって、各自の使い方に適したものを選ぶことで高画質かと高圧縮化が出来る。 CRF values range from 0 to 51, but sane values are somewhere between 19 and 26, depending on your source and what quality you want. Tonight the stream crashed at 18:58:17. Good compromises are usually between 15 and 23 or so. Video Encoder Settings: -preset medium -tune film -crf 17 I want to ask what happens under the hood when they specify both a Video bitrate and a crf value? Is the software effectively doing ffmpeg -i <input> -c:v libx264 -crf 17 -maxrate 10000K -bufsize ?? <output> If so, what bufsize does OBS uses? or is it doing something else? x264. RF 19-23 for 720p High Definition Obs Settings for Ryzen 5 3400g CRF closer to 14 if you need more quality, cpu preset to ultrafast to reduce cpu usage at the cost of increased filesize Unless you specifically need multiple audio tracks, you should use simple output mode, indistinguishable recording quality, software low cpu usage preset encoder (unless you have an nvidia video card, then choose nvenc h264 -v is the encoder params (here --rc 0 --enable-tpl-la 1 will enable crf as --crf itself is broken in the python av1an build, --qp 20 just will give a crf value which av1an target quality will replace so can be any value, --preset 6 is the preset go higher here due to target quality taking a signigifant performance chunk, --keyint 250 set it the 2) Record using CQP or CRF, not CBR. 1k 6 6 gold badges 64 64 silver badges 108 108 bronze badges. Lower values is better quality, but takes up increasingly more diskspace. Only doing local recordings not streaming. I was able to fix some of the issue by resetting OBS and using optimized settings for my laptop, is better but still a little choppy. But note that even when you want lossless video, highest quality possible, it's still recommended to compress using "nearly lossless" - basically a CRF value of around 5 will result in practically lossless Edit: I found CRF and ICQ to be better at their lowest settings, compared to vbr at their lowest settings. com ダウン With CFR and x264 and CPU preset veryfast, I am getting 2 MB for 30s video. CRF on veryfast causes extreme lag. He cambiado diferentes opciones, he visto varios videos, pero la calidad siempre es muy mala. For example, I recently started doing local recording for a steamer so we can have higher quality footage for YouTube. Anything lower than 12 should not be used unless you know what you're doing and why, as the file sizes get GIGANTIC very quickly. The range of the quantizer scale is 0-51: where 0 is lossless, 23 is default, and 51 is worst possible. ; Lossless Quality, Tremendously Large File Size the new PCM encoder started, While all of this is true OBS still needs GPU usage, 5-10% at 1080p60 depending on game and bitrate. Anything that isn't divisible by at least 4 will produce a nasty blur in OBS, but both 720p and 540p are divisible by 4 so they're both fine. I stream live content using OBS Studio. From 0 to 15, possibly 18, the human eye isn't able to detect any difference to the raw original. For more in-depth details on using CRF, take a look at this article:ht But yea you question about why its quality 12 (dont know if it already was answered), its because you use crf=20 , 22 is quality 10 in obs and the setting is inverted, so lower crf = higher quality balance. No changes in bitrate at all. The bottom line is that if you’re encoding with capped CRF crf 更人性化的cqp， 在高动态画面降低cq级别来节省磁盘空间 （因为高动态画面人眼难以捕捉细节，更高的画质可能作用不大，浪费磁盘空间）， 而低动态画面则会增加cq级别来提高细节保留 （因为低动态画面人眼将聚焦细节，更低的画质会令人厌烦，并且低 x264的默认速率控制（FFmpeg的默认h264方式）是CRF。 这允许比特率波动以维持目标质量水平。 Media SDK的ICQ和LA_ICQ是这类算法的最佳匹配。 测量比特率的困难. Now I have a ton of question :D 1. 1. 68 to 94. 30 GHz. Free, open source live streaming and recording software for Windows, macOS and Linux Members Online • Rawr_Mom. The quality lost though obviously is so minimal but for Obsessers, me :P, CRF at 18 is really the best for file size/quality output ratio in my opinion :-) Hope that helps :D JoeNumbers Hey everyone! I'm trying to perfect my obs settings as best as a can and so far it's been going well. High Quality, Medium File Size and the Indistinguishable Quality, Large File Size forces the 192 kbit/s bitrate (new AAC encoder started). A CRF value of 23 yields a quality level corresponding to CRF 19 for x264 CRF is the default rate control method, but VBR and CBR are also available. Make sure you replicate any issues as best you can, The higher your CRF value, the lower the file size and quality. 2-pass is like adjusting the overall boost, with some Hz adjustment. Free ScoreSight May 23, 2024; Version: v0. ScaryRage Member. In this In H. 264 and H. I have tried searching but there are so many posts I In this step-by-step tutorial, learn what the various OBS record settings mean and what to select to ensure that you record the best quality videos. There's a lot to unpack here. Edit: After lots of updates, preset 4 at CRF 20 is what I have settled on. Indistinguishable Quality preset is using CRF value of 16. I can see the difference between OG vs. Obviously it doesn't like something about the imported video, but I have no idea what. On forums going deep into the technology it's Comparison of the game on the screen, and the game on the raw video fresh from OBS Studio. I just installed obs-studio for screen recording, but I can’t record anything, the screen shows up in the preview. I'm looking for OBS recording settings that provide a good balance between quality and file size. Here's what Simple Output Mode does: OBS is using the rate CRF & CQP are basically use enough bits to get a certain quality. It's still going to be big, but less so that if you were recording in CBR Generally: The slower the preset, the higher the quality at the expense of time. Sane values are in the range 15-35. Share. Normally 16 is a very good image quality point, but if Hi, i have a problem with my new 4k iMac. OBS essential encodes incoming captured video and audio data and transmits that data via Real Time Messaging Protocol (RMTP). However, Restart OBS Start your stream/recording for at least 30 seconds (or however long it takes for the issue to happen). Hi, I just got hitfilm and I'm trying to import an MP4 I created by converting the MKV output of a OBS recording. 90 GHz Intel Xeon Jun 23, 2017 #3 As preset says, low CPU uses less compression (CPU aggresive) So, if you have a weak CPU and can´t use hardware encoder, it will be your best choice to avoid lag. Jul 23, 2017 #13 I'm playing with the thing using the last version ( and the little outdated one was doing the same thing) but no matter what value i put in the crf, it sticks to the cbr value entered under this mode. avsi script and place it to AviSynth plugins folder to be able to use "FFInfo" in your scripts. Reactions amd seems to perform not so good as nvenc/Quicksync/x264. CQP and CRF will change the bitrate dynamically depending on what is happining on screen. Windows Support. But for Ubuntu it is not showing up. The slightly harder route: Use "ultrafast" encoding preset, and set the CRF value lower, around 19-20 (if I remember correctly, 19 is what the OBS "method 2" uses). Stream to Twitch, YouTube and many other providers or record your own videos with high quality H264 / AAC encoding. YMMV. cpu usage: tried both fast and medium, but no change to dropped frames profile: high. Then, click the "Auto-Configuration Wizard". If you have an nvidia GPU, you can install Xaymar's StreamFX plugin and record in H265 HEVC with NVENC, which Use CQP or CRF for recording instead of CBR (constant bitrate). Processing this 443 Mbps video is not a bit rate issue. The higher the CQ parameter, the more detail is removed. A lower value generally leads to higher quality, and a subjectively sane range is 17–28. Jun 10, 2018 #1 Hey, I want to ask if there is any video quality diffrence between Keyframeintervall 0 (4. 4 Gig for 10 minutes). Apr 18, 2023 #2 OBS Studio Support. - CRF: 23 - Kayfram invterval: 0 - Uso de CPU presente: ultrarrápido (tengo un MSI Intel Core I7-10875 CUP 2. Code: In general, OBS does nothing differently. mp4 -c:v libx264 -preset veryslow -force_key_frames expr:gte(t,n_forced*2) -threads 8 -an -crf 23 -maxrate 2100k -bufsize 4200k BBB_2100_capCRF_23. ADMIN (A follow up to my NVENC lossless post) What is the equivalent of x264's CRF in h264_nvenc? (and some other questions) OBS is an open source cross platform software for live streaming and recording, and it is largely referred to as OBS Studio. I understand most terminology but two settings that I don't really understand very well are "keyframe interval" and "max b frames. The lower the number, the better the quality and the larger the files. Run some tests at CRF 23, and see how that impacts bandwidth My use case is different than that of the OP. My encoding settings are as follows: NVENC, High Quality, 8000 bitrate, 1080p60 Personally, I use CRF 17 for both 1080p and 4k. I'm using recording settings strictly btw. shadowplayといいどのデスクトップキャプチャーもみんなvfrでキャプりたがるのでほんとやめた方がいいと思う。 Fresh format on Streaming PC and Windows 11, OBS install. Rate Control: Opt for "CQP" or "CRF" as these will give a higher quality recording, but Download OBS Studio for Windows, Mac or Linux - for crf/cqp/icq rate control: the lower the control value, the better the quality but the higher the file size. For recording, it automatically sets CQP or CRF as rate control, which results in variable rate and high data volume, thus giving much higher Rate Control: CRF CRF: 23 Keyframe Interval: 0 s CPU Usage Preset: Superfast Profile: High You should see your OBS client have an option of x264 with other letters beside it for hardware encoding. Type: Standard, Format: mkv, Encoder: x264, Rate Control: CRF, CRF: 23, Keyframe: 2, CPU For myself, I'm doing a recoding step with postprocessing. Encoding overload in your case means your CPU cannot sustain the settings you've chosen. Oct 1, 2021 #2 Obs tries to record at a set framerate, which is set through Video > Settings. " It seems like most people recommend leaving both settings at CQP and CRF are quality targets, so this sort of thing could easily result in bitrate spikes of 100mb/s+ or so (and when youtube re-encodes most of this is getting thrown away). I'm spinning my wheels and starting to get frustrated so I'm asking for help. 41. 0 removes nothing, 50 removes almost all. there is no 動画を視聴いただきありがとうございます。無料の配信デザインソフト「OBS(Open Broadcast Software)」の使い方について、2022年最新版の情報を初心者 Hi, I wanted to ask you what are the best possible settings for recording (only) gameplays with my specs CPU: Ryzen 7 5800X GPU: AMD RX 580 8GB RAM: 16GB I have some bitrate problem when I record, for example, Dark Souls III, some areas, expecially the first, with foliage and fog destroys the CRF 23 (idk what it does, so i left it at default) keyframe interval 2. Would be great for IRL streams. I'm only recording the facecam video istelf, no audio or anything like that, just the video. Record to MKV or FLV and remux to MP4 from the Go to obs r/obs. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. It's not a recording-safe format, and the native-record mp4s that OBS produces cause problems with many editing suites. So try 22 first, then 21, 20 and so on. CQP (unless CRF is available) is my personal favorite method rate control. 18-23 is the Is there an expected percentage of dropped frames either with encoding lag or dropped frames? Is there a reason you're using x264 instead of nvenc or hardware encoding? Recommended settings when using Advanced Output mode. However, the program that uses how to render the option to make in vbr, I always put 30000 avg and 30000 of max, but recording in crf what can i The container I like most in OBS is mkv. 0 is lossless, higher numbers mean lower quality. Choose a preset. The algorithm uses whatever rate it deems necessary to maintain a quality of 18. Hey guys! I would really appreciate your help on setting OBS for game recordings cause I've been straggling and looking answers for several days in a raw INPUTS: Hardware - MacBook M1 2020 13' - 16Gb RAM - 8 GPU Monitor - 1440p Capture Card - Elgato HD60 X Games platform - PS5 Software - OBS (latest version) 最近研究obs推流编码中每个编码器的详细设置内容及影响，转篇文章作为设置参考。 ffmpeg -i input. CQP/CRF are quality-target based encodes, and will use as much or as little bitrate as is needed to maintain a constant image Recording (CQP / CRF) settings to account for quality loss when re-encoding with ffmpeg after the fact? through OBS several times at different settings - Lossless for a baseline, x264 CRF14, x264 CRF10 (well into diminishing returns), H264 CQP18, H264 CQP10 (as above), and H265 CQP24 (which is generally considered to be visually lossless Switch to CRF rate control and specify a quality setting between 14 (high quality) and 23 (good quality). r/obs. 0 is lossless, 50 is bloody mess. Recording on both of these was mostly static, just typing on documents and the same image. If I want smaller sizes I turn the CRF down since it will get me smaller file sizes with better quality. You are better off increasing the frame rate, resolution, or bitrate to improve the quality (in the case of recordings, a quality based rate limit all the way up to placebo would be better - OBS Studio Support. To compress true lossless RGB, you would need to set CRF mode in OBS, set the CRF value to 0 and then add --qp 0 in custom parameters. Since you're already on the fastest preset, the only thing you can do is either reduce load from other applications, or reduce frame size/frame rate. The equivalent ratecontrol method is LA_ICQ. vbr was set to 50mbs average and max 60mbs. C. I then convert this to a 443 Mbps DNxHR HQ via Resolve. If you have issues, then I believe you can also try setting the All clips have been encoded in a wide quality range, from --crf 8 to --crf 43. The downside is you have no control whatsoever of the bitrate. Extract and detect text from any OBS source in real-time, local on machine, always free. mp4 -c:v libx264 -crf 23 output. I explain why I use the veryslow preset here, and eight threads here. Something like CRF 23 with the veryfast preset can allow for very high quality even relative to higher bitrate CBR, while also using less Common CRF values are 18-23. I run Subnautica on medium graphics settings at 1080p and I also record a webcam in separate software on the same PC (I don't do this with the Ryzen PC tests which may be part of the reason why it does better lol). When i set my Window capture for recording from the browser (Pokèmon Showdown in particular) it has a bit lag that is extremely bad. Thread starter prantikv; Start date Oct 25, 2020; Tags recording CQP/CRF are image-quality based encoder targets, and will use as much or as little bitrate as needed to maintain a given image quality level. mkv -filter:v "setpts=PTS/360" -an -r 60 -c:v libx264 -preset slow -crf 10 timelapse. A better idea would be to use the Quality Balance/CRF value that results in the video The bottom line is that if you’re encoding with capped CRF and your CRF value is lower than 23, you’re probably wasting bandwidth on your easy-to-encode clips. It's the BEST container because you can easily convert it to MP4 for use on IOS devices, also you can keep your data in case OBS freezes or crashes. crayzcrinkle New Member. 23 is regarded as the best savings with minimal loss. 168K subscribers in the obs community. But OBS MP should output with CFR: From a video that i recorded. CRF did lower quality compared to a solid bitrate. No matter if i hit start streaming or record first rate control modes don't seem to Initial recording of the video is fine, but playback appears choppy. Few questions: 1. Question / Help and none presets with a crf of 16 which has been producing nice quality files but the CPU usage if fairly high when using this encoding method. Best. Stream Record: HEVC, CRF = 70 (this is not a normal CRF range, it goes 0-100, higher =better), High Game Record: x264, CRF = 20 (this is the typical 0-51, lower =better) ffmpeg -y -i BBB. CBR/VBR/CRF have such a tiny influence on system performance compared to every other CQP or CRF will maintain quality while adjsting bitrate to give you the best file size vs quality. Most of the content would be textual but there might be occasional jumps to web content (browser). Share Add a Comment. Those produce VMAF scores above 95% mean an mostly keep the 1% low over 93% (dips to 90% here and there). CRF is superior in pretty much every way. 265, CRF ranges from 0 to 51. Check all my cables and ensure proper connections. Then adjust as needed. The QSV encoder doesn't have a parameter called CRF. 23:06:23. This will effectively "target" -crf 23, but if the output were to exceed 1 MBit/s, OBS Studio 27. At CRF 15 the video detail is a very close match to gameplay. change Rate Control to CRF, make sure CRF number is 23, change Keyframe Interval to 2. It would be the same issue with NVENC recording on any GPU but the top end. This can reduce filesize quite a bit, but depending on the content, it can start to lose a small amount of quality over about 1080p 30fps x264 CRF 23 CPU vf key 1 colorf I444; 1080p 60fps x264 CRF 23 CPU vf key 1 colorf I444; What I'd like to see added to OBS Launch Parameters is the following: obs64. 0. Look for FFMS2. 3 works perfectly on WIndows with the AMD AMF HEVC encoder, all I did was just installing the latest OBS studio on windows. Rate Control. Practically indistinguishable from source material unless you zoom in to pixel level. An FFmpeg argument implementing The data rate and quality deltas between CRF 19 and CRF 23 for the hard-to-encode clips are much lower because the data rate cap controls bitrate and quality with these clips, not CRF. OBS 16 Lwks 12 and utube “Creator Studio OBS Studio Support. For high motion, a higher bitrate is required in this case, and for low motion less bitrate. Free, open source live streaming and recording software for Windows, macOS and Linux. 041: buffer size: 0 23:06:23. I wanna record in 1080p , 60fps. 22 is a good starting point. I'm getting an exclamation point in a yellow triangle. I cut and postprocess this video and export it with the x264 encoder with CRF=22. Follow answered Oct 14, 2017 at 7:43. One difference is that 720p is divisible by 8, and 540p is only divisible by 4. Record using CQP/CRF. CRF is a powerful encoding mode. Use CFR This will force OBS to output at a constant frame rate, duplicating frames if necessary to achieve this. I use OBS CRF 15 CPU H. Screen recording gets blurry when zoomed. I'm a Youtuber, so i need to record the screen clearly. From 18 to 25, you're beginning to see somewhat washed and blurred areas. -Update OBS-Change your base resolution to 1920x1080 in the video tab (and downscale filter lanczos)-Your current settings are TERRIBLE never use CRF on veryfast. 041: fps_den: 1 This now happen every time, even if I quit and relaunch OBS (which will produce a crash now). I dont wanna upload it I just wanna haev some high quality videos of me playing. com/playlist?list=PLG89gIGmm CRF is adjusting peaks and lows on every Hz, but you're leaving it to determine how that adjustment translates to your number, and you might not agree with it, or you might find it great. 16) and 2? I know that theres an delay added with using 0 but is there also an Restart OBS Start your stream/recording for at least 30 seconds (or however long it takes for the issue to happen). The lower the number, the higher the quality and the larger the size. New. 你们先搞清楚码率再说吧 我来告诉你 vbr cbr是什么意思 你在直播时填写的码率假如是1000，勾选cbr 就是说你的直播画面全部恒定1000码率填充 vbr就是最大1000码率填充， 在固态画面游戏（炉石）实用cbr更合适， fps类游戏(cf) 你就要选择vbr更合适 （静止画面跟移动画面填充恒定码率其结果就是移动 OBS (Open Broadcaster Software) is free and open source software for video recording and live streaming. obs中包含了非常丰富的设置选项，给予了用户非常多的自由度。 crf固定质量模式： 该模式下码率由crf质量值来进行控制，crf取值范围在1~51之间，h264编码的默认crf值为23，取值越低，编码质量越好，同时对cpu或者gpu的压力就越大。 If the internet were perfect, everyone streaming could use CQP (or better: any constant-quality mode like CRF or ICQ). Without further ado, let's start with the first comparisons! Presets comparisons (-1 -> 13) In the following graphs, you may find comparisons between all SVT-AV1 presets, ranging from the slowest --preset -1 to the fastest --preset 13. Ive been playing around with QuickSync and the cpu usage is so much lower (4% compared to 65% of x264) but despite the files sizes with A lower crf means higher output quality and larger file size. A lower value is a higher quality and a subjectively sane range is 18-28. While recording in OBS, you are bound by your framerate, so if you go too slow (medium Go to obs r/obs. Let's take a look at the key points of configuring it. crf 20 would equal qb=12 , crf 18 would be 13 etc. mkv The added parameters -c:v libx264 -preset slow -crf 10 order ffmpeg to encode with x264 with the slow preset and crf=10, just as the original recording with OBS. CBR wastes bitrate when no movement is happening, and might pixelate if a lot is happening. I'm having problems with my saved videos in OBS. I don't see cqp. They are too big and I use FFmpeg with these settings after the recording: ffmpeg -hwaccel cuda -i "VID_IN" -c:v libx264 -preset medium -crf 23 "VID_OUT" . I believe that this will help. 1: Looks like you've stumbled upon something I didn't realise OBS did! What I think is happening here is that since x264 can't encode to RGB (though there is an x264rgb variant you should have access to via the ffmpeg output in OBS that does do RGB), OBS is defaulting to feeding it the default, which would be 4:2:0. You can record as mp4 without worrying about crashes deleting your video if you record with these flags. Higher CRF value means less data, but less quality. 041: bitrate: 0 23:06:23. As far as I see right now, it's 'person' which is a bit excessive. Which of my two options would be considered better quality? OBS 23. You'll still see bitrate peaks in fast motion scenes, but it will try super hard to save bitrate in fast motion scenes. Yeah that twice the size and bit rate but even CQP 23 on NVENC looks better than CQP / CRF 18 on X264 which makes the file size about the same. Free, open source live streaming and recording software for Windows, macOS and Linux Therefore there must be some (nearly) equal quality values? E. stewhrynkiw New Member. CRF 23 is a high quality setting, CRF 14 is close to "indistinguishable" quality. Rate Control: CRF CRF: 23 Keyframe Interval: 0 CPU Usage Preset: veryfast (low CPU usage preset: superfast) Profile: High Tune: None To increase quality and file size, reduce the CRF value in increments of 1 (it's a logarithmic scale). No wasting bitrate on simple/slow scenes, no choking on fast-moving or complex scenes. The default is 28, and it should visually correspond to libx264 video at CRF 23, but result in about half the file size. Free, open source live streaming and recording software for Windows, macOS and Linux What I would even recommend is something like CRF with your CPU. It's a number I reckon is good for most situations. CRF: With OBS, you probably don't have access to this, but if you do I currently have my OBS settings set to CRF 15 with an ultrafast CPU usage preset, local recordings look fine, but when uploaded to youtube it seems to lose a lot of fidelity despite being exported with a 2 pass VBR of 30-60 mbps in premiere. CRF. CRF works just like in x264, so choose the highest value that provides an acceptable quality. CQP/CRF is the way to go, even if it means the output files may be rather large, they'll be a good quality capture. Usually superfast preset with high profile. There is the quality parameter of 0. For x264 your valid range is 0-51:. Common values for CQP are 13-18 and CRF are 18-23. CRF 18 for x264 or CRF 24 for x265 should be visually transparent; anything lower will probably just waste file size. mp4 如果你不确定要使用什么CRF，从默认值开始，并根据对输出的主观印象进行更改。如果质量没有足够好则较低的CRF。如果文件太大了则选择更高的CRF。 For OBS at least, putting it any slower than veryfast can disable many x264 optimizations. CRF is similar to CQP, except it will try to be more efficient overall. Static bitrates are best for streaming. ( OBS Settings, Output, Output Mode: Advanced. I'd say CRF at 23 (I believe default settings) was equivalent to something like 10,000 kbps. 22 is generally good-enough, 16 is visually lossless, 12 should only be used if you intend to edit the video later, to cut down on re-encoding artifacts. I always used CBR in 30000 to make my recordings, but it is not indicated and I want to change it to a crf of 15. OBS Studio Support. About audio in the Output Mode: Simple Same as stream - does nothing but simply copies the streamed data to the disk. 540p can still cause problems over something divisible by 8 in extremely obscure cases though, but those are probably not relevant. 16 will result in much larger files, but near-perfect video. 32GB RAM - Perfil: alto If you're recording, use CRF rate control (or CQP with NVENC) rather than a static bitrate. crf 23 isn't the same quality as cq 23 for nvenc h. Indistinguishable sets same CRF value for both x264 and x264 low CPU usage. Instead, OP should use X264 with CRF and not CBR. 5 fps if i use mp4 with the same settings (just switching container) it is constant framerate 60 like it should. I tried both the default settings and the settings in the page, didn't help. Add a Hi. I record with CQP 18 and a resolution of 2560x1440 (1440p), which yields a file size of 44 Gig for 1:40 hours of gameplay (4. true. The short answer is 'well, it isn't, unless CRF managed the same scene flawlessly. 与未压缩视频不同，编码比特流的帧大小预计会有很大差异。 However, YouTube compresses videos to around CQP 23. The short version is that 'x264 slow is better than nvenc' used to be the conventional wisdom, particularly during earlier iterations of Nvenc, but Turing encoders that came in with the 1650 Super and above (which may include your 1660 super) are pretty much toe to toe with slow. Stop your stream/recording. This is not exactly CQP=22, but roughly similar. Old. 50 that tell how much detail to remove. May 2, 2015 #3 AFAIK there is no CFR option in OBS MP. It is even more efficient than CQP, and even using the very fast preset, you can use a value like 18 and it should look fantastic. Record to MKV, and remux to MP4 after the recording is complete from OBS' File menu, Remux Recordings. CBR is for streaming. OBS will record the exact encoder settings used. ABR（Average Bit Rate）：即平均码率模式，该模式也是以质量为目标，和VBR相比，更加温和一点，实际码率波动不会那么大，但可能就会牺牲一点点的质量 Use CQP/CRF instead. dll and pdb files the crashes will stop occurring. Controversial. Audio is AAC passthrough. This is what is happening with the OBS Record to MKV, and remux to MP4 after the recording is complete from OBS' File menu, Remux Recordings. CRF Default being 23 will lower the file size of the output file while losing quality. CQP/CRF are quality-target based encodes, and will use as much or as little bitrate as is needed to maintain a constant image Though, CBR 20,000 will not look as good as CRF hitting those same bitrates, simply because of how their algorithms work. CRF and ICQ was set to 51. Hi! I wanna record games like Left 4 Dead 2 and wanna edit the material after recording. 22 is generally acceptable, 16 is very good/visually lossless, 12 should only be used if you plan to edit later, to mitigate re-encoding artifacts. ~25 should be equivalent to x264 CRF 23. Question / Help Keyframe Intervall 0 or 2? Thread starter ScaryRage; Start date Jun 10, 2018; S. Set Rate control to CRF; Set CRF to 23 for recording. 2) Record using CQP or CRF, not CBR. The linked thread is an encoder quality comparison, not a OBS benchmark or a demo how OBS may perform with certain settings. This is an attempt to recover the information, adding Before I was only using obs-studio and not good parameters for recording. 23 is a good default for x264, and 28 is the default for x265. Above 23, these areas become definitely visible. My output settings are as follows. Fastest hardware accelerated encode method: ffmpeg I did some tests yesterday and didn't expect that. If you change to CRF, the input field for the bitrate will vanish. so i can make some nice smooth edits. Open comment sort options. Any higher, you will see exponentially lower quality for less space. 041: crf: 23 23:06:23. We used CRF 20 with the preset of "faster" on a Go to advanced, check the box called "use cfr" in the video options section. The default is medium. Encode at CRF 28 but I imagine most people don't really care. Still, at CRF 23 you reduce the bitrate by 8. Gol D. https: Lower value represents better quality. This is what you see in the preview. 264 encoder and get 20-80 Mbps videos depending on game type. 57% but only reduce the VMAF score from 94. exe --canvas "3840x2160" (2560x1440, 1920x1080 and more resolutions) But if you use reasonable CRF values, in the range of, say, 23-17, this won’t occur. Windows Support . You could try crf=18 (or any value if you're curious) but beyond that file sizes tend to get prohibitively large. Gyan Gyan. Improve this answer. Window capture lags, but the cam no, so i really don't know what Actually it's not just bit rate. Only use CRF on ultrafast. The values for CRF are generally 18-23. So if you for example forget to stop recording on a black screen (which I've done before), you may not even need to put in the effort to trim out the footage to save space because it OBS Studioのインストール OBSの公式ページにアクセスします。Windowsをダウンロードします。 Open Broadcaster Software | OBS OBS (Open Broadcaster Software) is free and open source softw obsproject. VBR keeps this sane, and is probably better for longer recordings. I haven't been streaming, just recording. Mostly still images can be compressed to almost zero by using quality based rate controls (crf, cqp, icq). These values are kind of arbitrary, besides the fact that the higher number you go, the lower the bitrate and quality will be. If you want to be a successful Content Creator, then knowing how to record HIGH QUALITY videos for other platforms and with these StreamLabs OBS settings, yo It doesn't since I choose a rate control of CRF for Twitch and i Platform Operating system and version: Windows 10 2004 OBS Studio version: 26. The same happens with NVENC, I noticed just now. Muy pixelado. Last one uses ultrafast compression. mp4. For -crf replacement from libx264 may be -cq or -qp from h264_nvenc:-crf Select the quality for constant quality mode-cq Set target quality level (0 to 51, 0 means automatic) for constant quality mode in VBR rate control-qp Constant quantization parameter rate control method (from -1 to 51) (default -1). 2; Awesome plugin, runs great on my proxy server! I Really wish there was a dedicated 'face' detection though. Thread starter stewhrynkiw; Start date Apr 18, 2023; S. i feel no difference between having obs running 165 fps on gaming pc regarding frame drops, compared to if i dont run obs at all, which is why my Is there any way how to set OBS to record in CFR (constant frame rate) instead of VFR (variable frame rate)? I have tried to look in settings but couldn't find anything. Imagen adjunta. 使用FFmpeg中指定x264编码的crf值的示例如下。 ffmpeg -i input. Use CQP or CRF depending on your choice of encoder. Higher value means more detail removed, so the lower the crf/cq value, the higher the quality. Free, open source live streaming and recording software for Windows, macOS and Linux Members Although if you edit afterwards, I highly suggest you record high quality (crf 23-18) and maybe get an extra HDD if space is your concern. I record on x264 CRF on the CPU but if I play an intensive game with my GTX 1060 with uncapped frame rates and 99% GPU usage OBS starts having rendering. 264 and Quality based rate controls - Rates like CQP (or CRF for the CPU) work on letting the bitrate vary based on the actual video content that is being encoded. Using a The range of the CRF scale is 0–51, where 0 is lossless (for 8 bit only, for 10 bit use -qp 0), 23 is the default, and 51 is worst quality possible. I tried using CRF 10, which did improve visual quality slightly but the file size was too much. CRF tends to get better results than CQP when >0. 1 Expected Behavior Checking "Ignore streaming service setting recommendations" should work. If indistinguishable at 1080 is 15, and at 3440x1440 is 16, is it stupid to assume that since high quality at 1080 is 23, that high quality at 3440x1440 is 24? Also, is there a page somewhere that details all of OBS's settings that it uses for all recording methods in simple mode? For SVT-AV1 I recommend preset 5(/6) at CRF 24-28. Very useful for remux and having seperate audio files and converting to other formats. EXPAND FOR IMPORTANT LINKS & INFO OBS Studio MASTER CLASS PLAYLIST (all videos are here, in order): https://youtube. That refers to the Constant Rate Factor (crf). Microsoft Office (마이크로소프트 오피스) Office 버전 확인하는 법 PowerPoint(파워포인트) PowerPoint 모든 슬라이드의 제목만 복사하기 2. if I use mkv as container the video stream is variable frame rate 62. Here's what Simple Output Mode does: OBS is using the rate control mode "CRF" (or CQP in NVENC) set to 23 for "High" quality and CRF 16 for "Indistinguishable" quality. Make sure you replicate any issues as best you can, which means having any games/apps open and captured, etc. CRF affects the quality. Q&A. 생산성 앱 활용 팁 1. This is intended to make the video file compatible with editors that cannot handle VFR, and to maintain constant keyframe interval for streaming services that require keyframe interval to be set. Gameplay being captured at 480p (old retro shmups), but output resolution of OBS is 1080p 60fps, using Lanczos. 0 would be as close as possible to lossless. Reply reply If you want the same quality with the timelapse video (crf=10), you can use this: ffmpeg -i input. Seems like the video coming from my OBS Studio looks quite a bit blurrier than the game on my screen. Note: Parts of this guide were copied from the Handbrake Wiki but has been deleted there. 041: rate_control: CRF 23:06:23. Unfortunately, the scaling isn't the same between the encoders. 0 (64-bit, windows) log file uploaded at 2019-04 On its own, CRF is unusable for adaptive bitrate streaming, where data rates in the ladder rungs need to be limited. If encoding with x264 with crf=23 looks good, encoding with amd and cqp=23 may look worse, although the quality removal parameter mostly says the matroska = MKV and is the BEST container(why didn't the pricks just shorten it to MKV I'll never know). For the record, I tested on a Dell Precision 7820 Tower with two 2. Free, open source live streaming and recording software for Windows, macOS and Linux Question All I see is cbr, abr, vbr, and crf. Sort by: Best. zxcjci fxecq gpk kembtmqo hutccoam rqzoj fdkld nerml mdequ drxc
