O převodu M2TS na WebM

M2TS from Blu-ray carries H.264/H.265 video at 20-50 Mbps with AC3/DTS multi-channel audio. WebM is Google's open-source web video format using VP9 video and Opus audio in a Matroska-based container. VP9 delivers compression efficiency comparable to or exceeding H.265 while being completely royalty-free. Converting M2TS to WebM produces modern, efficient, open-source web video from the highest-quality consumer video sources.

Proč převádět M2TS na WebM?

WebM is the premium open-source alternative to MP4 for web video delivery. VP9 produces files 30-50% smaller than H.264 at the same quality, directly reducing bandwidth costs for video hosting. All major browsers (Chrome, Firefox, Edge, Opera, Safari 14.1+) support WebM natively. For video platforms, CDNs, and self-hosted video, WebM offers the best quality-per-byte of any widely supported format.

Jak to funguje

FFmpeg demuxes the M2TS and re-encodes using libvpx-vp9 for video and libopus for audio. VP9 encoding typically uses two-pass mode with a CRF target (31-35) and constrained bitrate for optimal quality distribution. Audio is transcoded from AC3/DTS to Opus at 128-192 kbps stereo — Opus is the best lossy audio codec available, surpassing AAC and Vorbis at all bitrates. The WebM container uses Matroska framing with WebM-specific restrictions (only VP8/VP9/AV1 video and Vorbis/Opus audio).

Kvalita a výkon

VP9 at CRF 31 with a 4 Mbps target for 1080p delivers excellent quality — comparable to H.264 at 6-8 Mbps. Opus at 128 kbps stereo outperforms AAC at the same bitrate. The combination produces web video that looks and sounds as good as much larger MP4 files. From a 20+ Mbps Blu-ray M2TS source, the VP9 output at 4-6 Mbps preserves virtually all perceptible quality.

Tipy pro nejlepší výsledky

1Use two-pass VP9 encoding for the best quality distribution — it is slower but produces more consistent results than single-pass.
2Target CRF 31 with a 4 Mbps ceiling for 1080p web video — this produces excellent quality at roughly half the size of equivalent H.264.
3Always provide an MP4 fallback alongside WebM for maximum browser compatibility using multiple source tags in HTML5 video.
4Opus at 128 kbps is superior to AAC at 192 kbps — use this bandwidth advantage to save space or allocate more bits to video.
5For very large M2TS files, consider AV1 encoding (also supported in WebM) for even better compression — but expect 5-10x slower encoding than VP9.

M2TS to WebM conversion produces the most efficient, open-source web video from Blu-ray and camcorder sources. VP9/Opus delivers outstanding quality at reduced file sizes compared to H.264/AAC.

Často kladené otázky

VP9 WebM offers better compression (smaller files at same quality) and is royalty-free. MP4 H.264 has broader device support, especially on older Apple devices. For web delivery, both are excellent choices.

VP9 uses complex algorithms (reference frames, loop restoration, superblock sizes) that require more computation than H.264. Two-pass mode doubles the time. The encoding cost is a one-time investment for better compression.

Safari 14.1+ (iOS 15+, macOS Big Sur+) supports VP9 WebM. For older Apple devices, provide an MP4 fallback.

Typically 30-50% at equivalent visual quality. A 1080p stream that needs 6 Mbps H.264 can be served at 3-4 Mbps VP9 — cutting CDN costs by a third.

Opus supports multi-channel audio up to 255 channels. However, most WebM players expect stereo. For surround web delivery, consider MPEG-DASH with channel configuration metadata.
