Chifukwa cha zinthu zambiri za hardware zomwe sizikuphunzira chilichonse chokhudzana ndi zinthu zatsopano komanso sizingatheke. DVD osewera, mayunitsi agalimoto, makamera osewera, mawonetsero amakampani ndi zida zambiri zofalitsa zofalitsa zimavomereza VOB ndi chilichonse chokhudzana ndi chilichonse. Kusinthana ndi njira yoyenera yotsika pamlingo, yogulitsidwa m'malo mwa ntchito pa chipangizo chomwe sichingakhale ndi njira ina. VOB amateteza zonse DVD payload - multiple angles, multiple audio zinenero ndi subtitle nyimbo zonse kupulumuka m'nyumba yake.

MKV ndi MOV amayendetsa ma audio osatha; MP4 amathandizira ambiri koma ena osewera a hardware amawona kokha track 1; WebM imatha pa Opus / Vorbis track. VOB ndi Video Object wonyamula anapeza mu VIDEO_TS wapamwamba wa aliyense DVD - MPEG-2 pulogalamu mtsinje ndi DVD-osiyana kuyendera deta anawonjezera.

+
MKV ndi WebM amalemba ma timestamps a real-frame ndi kuwongolera VFR mwanjira yachibadwa, kotero kuti MKV VFR imatha kukhala ndi VOB ya mafomuwa popanda kubwezeretsa. MP4 imasunga nthawi yowonjezerapo koma ena osewera amaganiza kuti CFR; wosintha amatulutsa "kulepheretsa CFR" kuti abwezeretse VFR MKV ku 24 / 30 / 60 fps VOB kwa zolinga zosatheka.
Remux ya codec yomweyo imatulutsa kukula kwakukulu (kuphatikiza kwa kontena kumasiyana ndi 0.1-2%). Kusintha kwa codec kungapangitse kukula kwa 50% kapena kuposa: H.264 kupita ku H.265 kumatha kuchepetsa fayilo pazomwe zimawoneka bwino; H.264 kupita ku AV1 kumatha kuchepetsanso panthawi ya slow.Kuchokera ku high-bitrate MKV (Blu-ray rip) kupita ku low-bitrate VOB (kutsitsa pa intaneti) ndichifukwa chofala kwambiri cha kugwa kwakukulu.
Ndiyo mpaka 8K (7680x4320) pa Premium. Mlingo wopanda malire umatha 4K (3840x2160) mpaka kumapeto kwa fayilo ya 1 GB. Ma remuxes oyera (kupita kwa codec yofanana) ya MKV yokulirapo kupita ku VOB amalepheretsa I / O ya diski, osati CPU - 30 GB MKV amasinthanso kupita ku VOB m'miphindi yochepa popanda kuyankhulana.
