MKV nthawi zambiri imabwerera ku decoding ya mapulogalamu pa hardware yomweyo - kulemera kwa CPU, chipangizo chotentha, ndi ma frame osunthika pa 4K. Kwa chipangizo chofunikira, MOV ndi chotetezeka chokhalamo. MKV ali pafupifupi palibe native hardware thandizo - foni, mawebusayiti ndi TVs nthawi zambiri ayenera VLC kapena remux pamaso iwo adzasewera.
Malinga ndi MOV ndi MKV ndi ma kontena oyambirira - omwe ndiyenera kusamalira?

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. MKV ndi Matroska, otsegulira chidebe anapanga mu 2002 ndi palibe kuvomereza zoletsa ndi palibe malire pa zimene angachite.

+
Ma subtitle olimba (ma tracks osankhika) amapulumuka pamene MKV angawagwiritse ntchito: MKV amagwiritsa ntchito SRT, ASS, SSA, PGS, VobSub mwachilengedwe; MP4 amagwiritsa ntchito mov_text (format yosasinthasintha). Kusintha MKV ndi subs a ASS ku MP4 kumawawononga kuti akhale mov_text kapena kuwalemba. Hardsubs (olembana mu kanema) amagwiritsa ntchito ngakhale.
Kodi MOV mpaka MKV amasunga masamba olemba / kuyendera kwa DVD?
+
Metadata ya bokosi limasintha pakati pa MOV ndi MKV pamenepo onse awiri amapereka bokosi la atomu (MKV, MP4, MOV). WebM imasunga bokosi m'ma block ogwirizana ndi Matroska, choncho MKV <-> WebM bokosi limayenda molimba. AVI sichimakhala ndi bokosi la spec, choncho kusintha kwa AVI ku MKV kumabweretsa fayilo yosasinthika ngati simuwonjezera ma markers m'manja.
Kodi ndi chiyani za MKV zowonjezera (fonti, kusindikiza) pamene mukupita MOV ku MKV?

HDR static metadata (HDR10 mastering display values, max content light level) imatha kupita ku MKV pamene ma kontena awiri ndi codec osankhidwa amathandizira (HEVC, AV1 mu MKV / MP4). Dolby Vision ndi wolimba kwambiri - DV profile 5 / 7 / 8.1 mu MOV nthawi zambiri amapulumuka okha ku MKV ndi HEVC; kusinthidwa ku MKV kontena lomwe silitha kunyamula gawo la DV limatha ku HDR10.
Kodi wosinthira MOV mpaka MKV adzasunga kusinthasintha kwa framerate (VFR)?
+
MKV ndi WebM amalemba ma timestamps a real-frame ndi kuwongolera VFR mwanjira yachibadwa, kotero kuti MOV VFR imatha kukhala ndi MKV ya mafomuwa popanda kubwezeretsa. MP4 imasunga nthawi yowonjezerapo koma ena osewera amaganiza kuti CFR; wosintha amatulutsa "kulepheretsa CFR" kuti abwezeretse VFR MOV ku 24 / 30 / 60 fps MKV 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 MOV (Blu-ray rip) kupita ku low-bitrate MKV (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 MOV yokulirapo kupita ku MKV amalepheretsa I / O ya diski, osati CPU - 30 GB MOV amasinthanso kupita ku MKV m'miphindi yochepa popanda kuyankhulana. Amasinthanso kukula ndi kuchuluka kwa ma pixel.
