2016年8月15日 · Simply put, CRF targets a certain quality level and will using whatever bitrate necessary to reach that quality. The quality of the video is known but the file size isn't. If you are not using CRF, and instead using a certain bitrate, then the file size is known but the quality is not.

2023年11月30日 · Recommended settings when using Advanced Output mode.

2021年3月1日 · For recording, my personal favorite is CRF rate control on X264 (or if you can hack obs to have it, X265). CRF provides the best compression for the best quality. Two examples:

2021年3月28日 · CRF or CQP should almost guarantee identical quality throughout a recording, it's really only a matter of filesize vs encoding load. One can always reencode the resulting file with slower presets and other encoding options, for long term storage.

2021年9月19日 · The higher your CRF value, the lower the file size and quality. If you have an nvidia GPU, you can install Xaymar's StreamFX plugin and record in H265 HEVC with NVENC, which will produce much smaller file sizes; a CQP of 22 is considered lossless there.

2016年2月7日 · CRF is a powerful encoding mode. Let's take a look at the key points of configuring it. For more in-depth details on using CRF, take a look at this article: http://slhck.info/articles/crf Lair...

CRF is a rate control method commonly used in video encoding to achieve a desired visual quality level. With CRF, instead of setting a specific bitrate, you set a target quality level, and the encoder adjusts the bitrate accordingly.

2024年8月19日 · With these optimized, high-quality OBS recording settings, you can start recording high-quality videos that meet your needs. Always balance video quality, file size, and system performance to ensure a seamless and professional recording experience.

2023年5月21日 · Use CQP or CRF for recording instead of CBR (constant bitrate). CQP and CRF will change the bitrate dynamically depending on what is happining on screen. CBR wastes bitrate when no movement is happening, and might pixelate if a lot is happening.

2022年9月7日 · Record using CQP/CRF. 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. 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.
