MPEG files come from DVD rips, old camcorders and TV capture cards. Compression is inefficient compared with H.264 so files are large. Choose MP4 to upload to social media, send in a chat app or play on any phone and TV.
Frequently asked questions
Will the MP4 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 MP4 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 H.264 with AAC audio.
