VOB kuya AVI Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyifaka kanjani ikhowudi VOB ku AVI ngaphandle kokulahlekelwa ukhwalithi yevidiyo?

Layisha phezulu ifayela lakho VOB futhi umguquli uqhuba i-CRF-based re-encode ebhekisa ku-visually-lossless AVI output (CRF 18 ngokuzenzakalela, amaxabiso aphansi = ifayela elikhulu / umgangatho ophezulu). I-codec ikhethiwe ukufana ne-AVI container — H.264 for broad-compat MP4, H.265 for size-efficient MKV, VP9 for WebM, AV1 for newer pipelines. I-VOB iqukethe i-MPEG-2 video, AC-3 noma umsindo we-PCM, kanye ne-DVD subpicture subtitle streams, ihlukaniswe ibe yi-1 GB segments yi-DVD spec. Amafayela we-AVI adlule ama-codecs amanje: cabanga i-MPEG-4 Part 2 (DivX/Xvid), Motion JPEG noma amafreyimu amnyama angacindezelwa ngaphandle kwe-H.264.

Yini ezoba nezinhlamvu zesihloko esingezansi kuhele lwami VOB?

Ngakhoni ukuba bahlale bekhethwa, ngoba AVI ayikho i-soft-subtitle stream egcina isihloko. Kunezindlela ezimbili zokuzikhipha: ukufaka kuvidiyo ngesikhathi sokuguqulwa, okuzozenza zihlala futhi zingashintshwa, noma ukuthumela njenge.srt ehlukile ecaleni le AVI ukuze umdlali alayishe. Umguquli utshela ukuthi yini eyayenza ngaphandle kokushiya isihloko ngokucophelela. I-AVI ayinaso isixhaso esisemthethweni se-codecs yamanje, isilinganiso sefreyimu esiguqukayo, izihloko ezithambile noma amafayela angaphezu kuka-4 GB ngaphandle kokuhlaselwa, futhi i-chunk ngayinye i-overhead ibhoboza ifayela.

Kungani ihele lami VOB lingakwazi ukushintsha ku AVI?

Kuyinto evamile kakhulu i-DRM. Ezinye VOB izithombe zibhalwe ngokufihlakele ku-bitstream level yisitolo noma isofthiwe eyenza, futhi isithombe esibhalwe ngokufihlakele asikwazi ukucinywa yithu noma yinoma yini ngaphandle kwesitshixo selayisense. Izithombe ongazirekhodile, ozenzayo noma ozibhumele ngaphandle azikhuselwanga ziguqulwa ngokuvamile; ukuthenga okusemthethweni akuzokwenza, futhi akukho oguqulelayo angazethemba ngokuvumelana.

AVI ngokuvamile ibuyela emuva ku-software decoding ku-hardware efanayo - u-CPU ophezulu, isisetshenziswa esipholile, namafreyimu akhuphuka ku-4K material. Uhlelo oluzosetshenziswa, VOB luyi-container ephephile yokuhlala kuyo.

Kuxutshwe phansi ku-stereo, ngoba AVI ayikho indlela ethembekile ye-multichannel. Ukuvala ngezansi kusetshenziswa izilinganiso ezijwayelekile ze-ITU ukuze ukuxhumana engxenyeni ye-channel ihlale icacile futhi izimo zifike ku-level ephansi kune-emnyama. Noma yini esekelwe ku-channel ehlukile ihlala ikhona ngemuva kwalokho.

Ingabe kukhona okushintshayo phakathi kwefomethi ezimbili ezidalayo njenge VOB ne AVI?

Uma nje ingxenye ekhethekile yemishini idinga isiphetho. Ifomethi zombili zivela kusikhathi esifanayo se-H.264, ngakho noma yikuphi ukushintshana kuthengiswa ukusebenza kahle, ukhwalithi noma ubufakazi bokuphila - kuthengiswa ukuhambisana nedivayisi eyodwa ekhethekile. Uma inhloso ukugcina isithombe esisetshenziswayo isikhathi eside, ukuguqula kwibhokisi elikhona endaweni ye-sideways.

Yini i-codec yevidiyo i AVI isebenzisa?

Kuxhomekeka ku AVI isiqoqi. MP4 iphutha ku-H.264 ukuze kuxhaswe ukusakazwa okubanzi phakathi kwamafoni, amabhuleki, nama-Smart TVs. MKV iphutha ku-H.265 / HEVC ukuze kufinyelelwe isigamu sesayizi yefayela ngekhwalithi elinganayo. WebM iphutha ku-VP9. Izinketho ezithuthukisiwe zibonisa ukhetho lwe-codec olucacile uma ufuna ukucima.
