2024/3/30 -Maybe I've just been spoiled, but x264 has such good defaults I have a hard time justifying changing them, crf 23 is a few points below almost visually ...

2024/4/18 -As with x264, you need to make several choices: Choose a CRF. CRF affects the quality. The default is 28, and it should visually correspond to libx264 video at ...

2024/1/30 -A lower CRF value indicates a higher quality level and a higher bitrate, while a higher CRF value indicates a lower quality level and a lower bitrate. The CRF ...

2024/2/21 -x264 is a software library and command line application for encoding H.264 / AVC developed by VideoLAN, the people behind the ever-popular VLC Media Player ...

2024/4/23 -The idea is that a given CRF value should give you roughly the same quality relative to the source each time (assuming all other settings are the same), but as ...

2024/5/9 -What is the difference between -crf and -cq parameters of ffmpeg ? I am trying to compress 1080p h264 videos into 1080p h265 videos with high quality and low ...

2023/12/31 -In short, CRF compresses a video based on visual quality, rather than targeting a specific bitrate/file size. x264 is an older incredibly widely supported codec ...

2024/1/5 -configure settings for recording to a file; encoder x264; rate control crf with crf=17; set some presets and tuning for the x264 encoder. These are quite ...

2023/12/25 -Use the crf (Constant Rate Factor) parameter to control the output quality. The lower crf, the higher the quality (range: 0-51). The default value is 23, ...

2024/1/8 -In addition to the "default" two-pass modes, there's a constant quality (CQ) mode (similar to CRF in the x264 encoder) that targets a certain perceptual quality ...
