DVD VOBs use MPEG-2 video with AC3/DTS audio — patented codecs from the 1990s. WebM is Google's open container using VP8/VP9/AV1 video with Vorbis/Opus audio — all royalty-free. WebM is natively supported by Chrome, Firefox, Edge, and Opera, and is YouTube's primary delivery format. Converting VOB to WebM modernizes DVD content for web delivery.
WebM with VP9 or AV1 delivers dramatically better compression than MPEG-2 — the same visual quality at a fraction of the file size. Converting DVD content to WebM produces web-ready files that play natively in all modern browsers without plugins. VP9 at DVD resolution produces files roughly 70-80% smaller than the original VOB at comparable quality.
For open-source and royalty-free requirements, WebM replaces MPEG-2's patent-encumbered codecs with completely free alternatives.
FFmpeg deinterlaces the VOB's MPEG-2, decodes AC3/DTS audio, and encodes to VP9 using libvpx-vp9 with Opus audio using libopus in the WebM container. VP9 uses CRF mode (31-36) or two-pass encoding. AV1 via SVT-AV1 is available for even better compression. DVD resolution is preserved. Deinterlacing via yadif produces progressive frames for web display.
VP9 at CRF 31 produces excellent quality from DVD sources — visually superior to MPEG-2 at dramatically smaller file sizes. AV1 achieves even better results. The deinterlacing and modern encoding produce a cleaner image than the original interlaced MPEG-2 playback.
