Video FilesMP4 is the most universally supported video container format. It typically uses H.264 or H.265 video codecs with AAC audio, providing an excellent balance of quality and file size across all devices and platforms.

Video FilesMPEG is an early digital video standard that formed the basis for later formats like MP4. MPEG-1 and MPEG-2 files are common in DVD rips and older digital video archives.
Informazioni sui file MPEGConfronto dei punti di forza
MP4 Punti di forza
- Universal playback — every browser, phone, TV, game console, and editing suite reads MP4.
- Supports modern codecs (H.264, H.265, AV1) with no container changes.
- Progressive streaming works with the "moov atom" at the start of the file.
- Carries subtitles, chapters, multiple audio tracks, and embedded metadata.
- ISO-standardized (ISO/IEC 14496-14) and patent-licensable via MPEG LA.
MPEG Punti di forza
- Universal playback on every OS, player, and DVD/TV hardware since 1995.
- Proven, well-documented — three decades of spec refinement and tooling.
- Best-in-class for broadcast — Transport Streams carry multiple channels, error correction, and PSI/SI metadata.
- Low CPU decoding — even 1990s hardware can handle MPEG-1/2.
Limitazioni
MP4 Limitazioni
- Codec licensing (H.264, H.265) carries royalty costs for commercial use.
- Streaming requires the moov atom at the start — a misplaced atom breaks web playback.
- Not ideal for lossless or professional editing workflows (use ProRes or DNxHD instead).
- Editing an MP4 almost always re-encodes, degrading quality.
MPEG Limitazioni
- Aging codec — MPEG-2 is 2-3× larger than H.264 at equivalent quality.
- Patent licensing still active for some MPEG-2 patents in certain territories.
- Consumer devices rarely default to .mpg — everything ships as .mp4 today.
- No modern features (HDR, HEVC, AV1) inside classic MPEG Program Streams.
