Losslessly converts animated GIF to AVI for high-quality YouTube upload:
ffmpeg -i my.gif -vcodec huffyuv my.avi
YouTube Lossless codec uploads
Currently, lossless HuffYUV works for YouTube uploads. HuffYUV is a primitive lossless compression algorithm, but you don’t want YouTube to doubly-lossy encode a lossy input video.
YouTube does not currently accept the lossless codecs:
- ProRes: Video codec isn’t recognized by YouTube
- FFV1: Video is often heavily clipped horizontally, half the video panel is missing
