MPEG files come from DVD rips, old camcorders and TV capture cards. Compression is inefficient compared with H.264 so files are large. Choose WebM to embed video on a website using open, royalty-free codecs.
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 MPEG to WebM re-encode the video?
Rarely: the codecs are not compatible, so the video is re-encoded. A typical MPEG contains MPEG-2 video with MP2 audio. Otherwise the result is VP8 with Vorbis audio.
