Encode/H.265 â€“ FFmpeg
This guide focuses on the encoder libx265 which can offer around 25â€“50% bitrate savings compared to H.264 video encoded with libx264, while retaining the same visual quality. These gains will be most pronounced at resolutions of 1080p and higher. See HWAccelIntro for information on supported hardware H.265/HEVC encoders. Getting ffmpeg with libx265 support ffmpeg needs to be built with the --enabl

Encode/VFX â€“ FFmpeg
Using ffmpeg in a VFX pipeline Every VFX pipeline needs a way of converting still frames into motion sequences that can be played back on a large screen or projector (and/or directly on artists' workstations) for the purposes of doing a review or just seeing the resulting work in motion. It is perfectly possible to play back high resolution frames directly, but such a setup requires an incredible
