MPEG and MOV explained
MPEG-1 and MPEG-2 program streams are the formats behind Video CDs and DVDs. They are decades old and very inefficient by modern standards.
MOV is Apple's QuickTime container. Structurally it is very close to MP4 — the two share an ancestor — but MOV files often use codecs like ProRes that general-purpose players cannot decode.
- Where MPEG files come from
- DVD rips, old camcorders and broadcast archives.
- Where MOV is used
- iPhone and Mac screen recordings, and professional video editing.
