Frequently asked questions
Will the WebM lose quality?
Both formats are lossy, so converting re-encodes the data once more. Using a high quality setting keeps the generational loss very small. Avoid converting the same file back and forth repeatedly.
Does converting AVI to WebM re-encode the video?
Rarely: the codecs are not compatible, so the video is re-encoded. A typical AVI contains MPEG-4 Part 2 (DivX/Xvid) or Motion JPEG video with MP3 or AC-3 audio. Otherwise the result is VP8 with Vorbis audio.
