Über WEBM-DateienVorteilsvergleich
AVI Vorteile
- 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.
WEBM Vorteile
- Patent-free and royalty-free — no licensing worries for encoders.
- First-class HTML5 <video> support across browsers.
- AV1 inside WebM offers best-in-class compression (30-50% smaller than H.264).
- Low overhead — the container strips everything MKV does not need.
- Powered by battle-tested libvpx and dav1d reference decoders.
Einschränkungen
AVI Einschränkungen
- 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.
WEBM Einschränkungen
- Limited codec palette — cannot carry H.264 or HEVC streams.
- Encoding AV1 or VP9 at quality is slow.
- Hardware decoders for AV1 are still catching up on older devices.
- Professional video tools (Final Cut, Premiere) do not export WebM natively.
