Sobre os arquivos MPGComparativo de vantagens
MP4 Vantagens
- 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.
MPG Vantagens
- Universal legacy support.
- Trivially rewrappable to .mp4 without re-encoding.
- Low decoding overhead.
Limitações
MP4 Limitações
- 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.
MPG Limitações
- Aging codec — larger files than modern alternatives.
- No HDR, no modern audio, no modern subtitles.
- Mostly legacy — not used for new production.
