WebM ku VOB Mafunso Ofunsidwa Kawirikawiri Okhudza Kusintha kwa Anthu

Kodi ndingatani kuti ndibwezeretse WebM ku VOB popanda kuwononga mtundu wa kanema?

Ikani fayilo yanu ya WebM ndipo wosintha amayendetsa CRF-based re-encode yoyang'anira kutulutsa kwa VOB (CRF 18 mosalekeza, matanthauzo ochepa = fayilo yayikulu / yapamwamba). Codec imasankhidwa kuti igwirizane ndi VOB - H.264 kwa MP4 yokhala ndi kutalika, H.265 kwa MKV yokhala ndi kukula, VP9 kwa WebM, AV1 kwa ma pipelines atsopano. WebM ndi mwanzeru m'mbali: VP8 kapena VP9 kanema (AV1 zaposachedwapa) ndi Vorbis kapena Opus audio, ndi chilichonse chinachake. A VOB ali MPEG-2 kanema, AC-3 kapena PCM audio, ndi DVD subpicture subtitle masamba, anagawa mu 1 GB segments ndi DVD spec.

Kodi VOB angagwiritse ntchito nyimbo zambiri kuposa imodzi?

Ndikoyenera, ndipo ndi chithandizo choyenera pa WebM. VOB imachita chilichonse cha audio monga chida chabwino kwambiri, choncho mgwirizano wachilankhulo chachikhalidwe, dub ndi woyang'anira woyang'anira amatha kukhala m'fayilo imodzi ndi wosewera yemwe amasintha pakati pawo pazosowa. VOB amateteza zonse DVD payload - multiple angles, multiple audio zinenero ndi subtitle nyimbo zonse kupulumuka m'nyumba yake.

Kodi VOB imathandizira masamba olemba omwe WebM sanachite?

Amachita. VOB amasunga masamba monga metadata ya kontena, kotero kuti kujambula kwanthawi yayitali kungagwiritsidwe ntchito pogwiritsa ntchito gawo lomwe limatha kusinthidwa pogwiritsa ntchito bar ya progress. WebM sichingakhalepo kuti ipereke mfundozi, chifukwa chake ngati chiyambi chidatumizidwa ndi mndandanda wa kapitoli, chidapezeka mu fayilo ya sidecar - bweretsani kuti musinthe ndipo chimalemba mu VOB.

Kodi ndingapezebe fayilo patsamba la webusaiti pambuyo posintha WebM ku VOB?

Sizokha. WebM imasewera m'masamba onse a masamba; VOB sichichita, chifukwa chake tsamba lophatikizira limabwerera ku download link kapena frame ya wosewera mpira wopanda.

VOB ndi kugawidwa pakati pa mafayilo, angagwiritsidwe ntchito CSS-encrypted, ndi kunyamula navigation packets kuti kukhumudwitsa cholinga chazikulu osewera.

Nchifukwa chiyani ndingasinthire WebM ku mtundu wachikhalidwe monga VOB?

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.

Kodi ndi codec iti ya video yomwe VOB imagwiritsa ntchito?

Izi zimadalira bokosi la VOB. MP4 imasinthidwa ku H.264 kuti ithandizire kusewera kwa mafoni, mawebusayiti ndi Smart TV. MKV imasinthidwa ku H.265 / HEVC kwa pafupifupi theka la kukula kwa fayilo pazomwe zimafanana. WebM imasinthidwa ku VP9. Zosankha zazikulu zimawonetsera kusankhidwa kwa codec ngati mukufuna kuchotsa. VOB ndi Video Object wonyamula anapeza mu VIDEO_TS wapamwamba wa aliyense DVD - MPEG-2 pulogalamu mtsinje ndi DVD-osiyana kuyendera deta anawonjezera.

Kodi nyimbo yanga ya audio idzapulumuka ku WebM kupita ku VOB?

Ndiko. Ngati WebM ndi VOB amagawana codec ya audio (mwachitsanzo, onse amagwiritsa ntchito AAC), audio imasinthidwanso popanda kusinthidwanso - bit-identical. Ngati codecs amasiyana, audio imasinthidwa kukhala AAC / Opus / Vorbis malinga ndi zomwe VOB zimathandizira. Audio yokhala ndi ma track ambiri (mawu owonjezera, mabungwe) amasungidwa.

Kodi ndingapeze bwanji chiwonetsero chazithunzi chakale posintha WebM ku VOB?

Ngati mukufuna kusintha mtengo (mwachitsanzo, interlaced 29.97 → progressive 30, kapena 60 → 30 kwa kutsitsa), mfundo ya framerate imayendetsa 3: 2 pulldown, deinterlacing, ndi frame-blending mu gawo limodzi lokha la encoding.

Kodi kukula kwa fayilo isintha bwanji kuchokera ku WebM kupita ku VOB?

Same-codec re-mux (WebM H.264 → VOB 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.

Kodi fayilo ya VOB idzasewera pa iPhone, Android ndi Smart TVs?

MP4 / H.264 imasewera mwachilengedwe pazinthu zonse zamakono. MOV / H.264 imasewera pazinthu za Apple ndi ma TV ambiri koma si nthawi zonse pa Android oyambirira. MKV iyenera VLC pa iOS.
