Codec imasankhidwa kuti igwirizane ndi WebM - H.264 kwa MP4 yokhala ndi kutalika, H.265 kwa MKV yokhala ndi kukula, VP9 kwa WebM, AV1 kwa ma pipelines atsopano. A VOB ali MPEG-2 kanema, AC-3 kapena PCM audio, ndi DVD subpicture subtitle masamba, anagawa mu 1 GB segments ndi DVD spec. WebM ndi mwanzeru m'mbali: VP8 kapena VP9 kanema (AV1 zaposachedwapa) ndi Vorbis kapena Opus audio, ndi chilichonse chinachake.

Ma frame ophatikizidwa amasunga madera awiri apakati omwe amatenga masentimita asanu ndi awiri; pafoni kapena monitor ya progressive-scan yomwe imawerenga ngati chotchinga chozungulira pa chilichonse chomwe chimayenda. Ikani njira yosinthira ndipo encoder imapanga madera onse m'ma frame opitilira muyeso pambuyo polemba WebM. VOB ndi Video Object wonyamula anapeza mu VIDEO_TS wapamwamba wa aliyense DVD - MPEG-2 pulogalamu mtsinje ndi DVD-osiyana kuyendera deta anawonjezera.

Zithunzi zanga za VOB zimagawidwa m'magawo owerengeka - kodi WebM ali ndi malire ofanana?

Sichoncho, ndipo ndi imodzi mwazinthu zabwino kwambiri zosamukira. Konteni ya VOB ili ndi bokosi lokha lokha lomwe limatha kuyendetsa mavidiyo ochepa kapena otsika kwambiri, chifukwa chake makamera oyambirira amafika ngati part1, part2, part3. WebM salinso ndi malire ofanana, chifukwa chake masamba amatha kuphatikizidwanso mu fayilo imodzi yopitilira.

Sankhani gawo lomwe mukufuna poyamba; ena amaphunzitsidwa bwino ku mafayilo awo oyambirira kuposa kuchoka m'chipinda chokhala ndi ma CD omwe amawateteza. VOB amateteza zonse DVD payload - multiple angles, multiple audio zinenero ndi subtitle nyimbo zonse kupulumuka m'nyumba yake. WebM ndi woipa fit kulikonse kunja kwa browser - video olemba, foni's native galleries ndi Smart TVs kwambiri ku ignore izo.

Nchifukwa chiyani fayilo yanga VOB siyisintha kukhala WebM?

Zina VOB mafayilo amasinthidwa pa level bitstream ndi sitolo kapena pulogalamu yomwe idatulutsa, ndipo kusinthidwa kwa encrypted stream sikungathe kusinthidwa ndi ife kapena ndi chilichonse popanda chida cha lisensi.

Same-codec re-mux (VOB H.264 → WebM H.264 just changing container): nearly identical size. Codec change can swing dramatically: H.264 → H.265 typically halves the file at the same visual quality; VP9 is roughly comparable; AV1 cuts another 20-30% but is slower to encode.
