MKV vs AVI
Hauv cov ntaub ntawv video siv hauv computer, peb tuaj yeem pom cov ntaub ntawv txuas ntxiv mp4, m4v, avi, mkv, vob thiab ntau lwm yam. mkv thiab avi feem ntau pom cov ntsiab lus ntawm cov ntaub ntawv video. Nyob rau hauv qhov tseeb, cov no tsuas yog wrappings siv los ua ke cov ntsiab lus; i.e. cov ntaub ntawv audio thiab video, sab hauv. AVI hom tau tsim los ntawm Microsoft thaum ntxov 1990's, thiab mkv tau qhia hauv 2002.
AVI
AVI stands rau Suab Video Interleav e, uas yog lub thawv ntim ntau hom tsim los ntawm Microsoft rau qhov rais operating system ib puag ncig. AVI yog tsim los ntawm Resource Interchange File Format (RIFF), uas yog yav dhau los proprietary hom ntawm Microsoft thiab IBM. AVI yog tsim los rau synchronous ua si ntawm ob lub suab thiab video ntaub ntawv. AVI compress cov ntaub ntawv los yog siv uncompressed cov ntaub ntawv encoding; Yog li ntawd, lub suab / video zoo ntawm cov hom yog nyob ntawm qhov compression. Feem ntau cov ntaub ntawv yog encoded nrog uncompressed los yog tsawg compression piv. Yog li ntawd, cov ntaub ntawv AVI zoo tib yam siv qhov chaw cia ntau dua.
Hauv AVI cov ntaub ntawv, cov ntaub ntawv xov xwm tau muab khaws cia rau hauv chunks (feem ntau nyob rau hauv tag nrho cov RIFF derivatives), qhov twg AVI ntaub ntawv nws tus kheej yog ib tug chunk, uas yog ntxiv muab faib ua ob yuav tsum tau "chunks" thiab ib tug xaiv "chunk". Cov chunks hdrl thiab movi yog qhov yuav tsum tau ua thiab idx1 chunk yog xaiv tau. Metadata tuaj yeem khaws cia rau hauv cov ntaub ntawv chunk ntawm cov ntaub ntawv.
DV AVI yog daim ntawv compressed ntawm AVI uas ua rau cov ntaub ntawv hom ntawv, kom nws sib xws nrog DV hom. Txij li thaum txoj kev loj hlob ntawm AVI, cov yam ntxwv tshiab tau tsim nyob rau hauv digital video thev naus laus zis, thiab cov qauv ntawm AVI hom ntawv tiv thaiv kev koom nrog cov kev hloov pauv no rau hauv cov ntaub ntawv hom. Yog li ntawd, qhov nrov thiab kev siv ntawm cov ntaub ntawv hom tau poob.
YMKV
MKV yog hom khoom ntim tawm, uas yog ob qho tib si qhib thiab pub dawb. Nws muaj npe tom qab Lavxias teb sab zes menyuam roj hmab thiab hu ua Matroska Multimedia Thawv. Nws tau muab lub npe no tshwj xeeb vim tias lub thawv ntim muaj peev xwm tuav tau ib tus lej ntawm cov ntaub ntawv ntws hauv ib cov ntaub ntawv. Nws yog kiag li qhib specification thiab qhib qhov chaw platforms thiab software siv thiab txhawb nws ntau.
MKV cov ntaub ntawv tuaj yeem tuav ntau qhov kev tshaj tawm hauv tib cov ntaub ntawv. Piv txwv li, ib tug yeeb yam yuav encoded nyob rau hauv MKV kom muaj suab lem nyob rau hauv ob hom lus, nyob rau hauv tib cov ntaub ntawv. Txoj kev xav tau tuaj yeem xaiv tau thaum ua si. Tus kheej lem ntawm cov ntaub ntawv xov xwm tau txais kev cawmdim raws li ib tus neeg cov ntaub ntawv kab. Conceptually, nws zoo ib yam li MP4 thiab AVI cov ntaub ntawv tawm tswv yim, thiab qhia cov chunk raws li architecture. Vim li no, nws yooj yim dua los hloov thiab khaws cov ntaub ntawv multimedia hauv MKV hom. Tsis tas li ntawd, MKV hom tso cai rau khaws cov ntaub ntawv ntau tshaj plaws hauv ib cov ntaub ntawv, yooj yim dua.
Ntau tus neeg siv xov xwm tsim tawm rau lub Windows thiab Mac platforms tam sim no txhawb nqa MKV cov ntaub ntawv hom; Yog tias tsis yog, txhim kho cov codec generic zoo li K-lite codec pob yuav pab kom cov neeg ua si khiav MKV cov ntaub ntawv.
MKV vs AVI
• Ob leeg MKV thiab AVI yog ntim rau cov suab thiab yees duab (sib txawv ntawm cov ntawv encoding).
• MKV yog lub thawv qhib hom thaum AVI yog hom ntawv ntim khoom tsim los ntawm Microsoft.
• Ob leeg siv tau cov codecs uas nquag siv xws li h.264 thiab A3C, tab sis AVI muaj kev txwv rau H.264/AVC. Yog li ntawd, cov ntsiab lus HD tej zaum yuav tsis muaj.
• AVI tsuas khaws tau ib qho video kwj thiab ib lub suab nkaus xwb thaum MKV khaws tau ob peb lub suab thiab cov kwj tawm hauv tib cov ntaub ntawv (container).
