Sobre os arquivos MTSComparativo de vantagens
MP4 Vantagens

- Progressive streaming works with the "moov atom" at the start of the file.
- Carries subtitles, chapters, multiple audio tracks, and embedded metadata.

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.
MTS Limitações
- Slow to decode — editors typically transcode for editing.
- Proprietary folder-structure conventions complicate direct import.
- Largely legacy as smartphones replaced dedicated camcorders.
- 192-byte packet format adds overhead vs plain TS.
