Sobre os arquivos DVComparativo de vantagens
AVI Vantagens
- Simple, well-documented format — trivial for any video library to parse.
- Universal Windows playback since Video for Windows in 1992.
- Low encoding overhead — interleaved structure is fast to write.
- Works with any codec technically, including modern ones.
DV Vantagens
- Lossless capture from tape via FireWire.
- Each frame compressed independently — editing without intermediate transcoding.
- Universal support in every pre-2010 NLE.
- Fixed 25 Mbps bitrate — predictable storage and edit performance.
Limitações
AVI Limitações
- Aging container — no native support for chapters, subtitles, or multi-audio selection.
- File-size limits (2 GB original, 4 GB with OpenDML) break for HD content.
- Variable-framerate video causes sync drift.
- Larger than equivalent MP4 or MKV due to container overhead.
- Poor support on iOS and Android.
DV Limitações
- Legacy — camcorders and tape decks are out of production.
- Large files vs modern codecs (13 GB per hour).
- Interlaced video requires deinterlacing for modern displays.
- FireWire ports disappeared from PCs around 2012 — archive-capture is a specialty now.
