MPEG kuya MPG Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyifaka kanjani ikhowudi MPEG ku MPG ngaphandle kokulahlekelwa ukhwalithi yevidiyo?

Layisha phezulu ifayela lakho MPEG futhi umguquli uqhuba i-CRF-based re-encode ebhekisa ku-visually-lossless MPG output (CRF 18 ngokuzenzakalela, amaxabiso aphansi = ifayela elikhulu / umgangatho ophezulu). I-codec ikhethiwe ukufana ne-MPG container — H.264 for broad-compat MP4, H.265 for size-efficient MKV, VP9 for WebM, AV1 for newer pipelines. Ividiyo yi-MPEG-1 noma i-MPEG-2 ne-MP2 noma i-AC-3 umsindo, ehlukaniswe ibe yizinkulumo ezilungiselelwe ukucutshungulwa nge-hardware esebenza kahle. Okuqukethwe yi-MPEG-1 noma i-MPEG-2 video ne-MP2 umsindo; ukuxhuma kanye nesakhiwo se-GOP kufana nehele le-.mpeg.

Ingabe MPEG ingaguqulwa ibe MPG ngaphandle kokuphinde ubhale kabusha ividiyo?

Yebo, futhi yindlela esheshayo. MPEG ne MPG zihlanganisa isakhiwo sebhokisi esifanayo esingaphansi, ngakho ividiyo nesandi sokushayela zikopiwe nge-byte-by-byte futhi isiqoqi sokushayela kuphela sibhale kabusha. Akukho okuqokwa futhi akukho okucindezelwa, ngakho ihele lezici ezide liqedwa ngaphansi kwemizuzu endaweni yehora elilodwa, nekhwalithi yesabelo esifanayo nesomthombo. I-MPEG lapha ibhekisa ku-MPEG-1 noma MPEG-2 izinhlelo ezihambayo, ifomu elijwayelekile le-Video CD bese le-DVD ne-broadcast television. MPG iyi-MPEG i-program stream efanayo ne-.mpeg — isibonisi sokubhala esithathu siyi-DOS-era truncation, hhayi i-format ehlukile.

Ingabe kukhona okushintshayo phakathi kwefomethi ezimbili ezidalayo njenge MPEG ne MPG?

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. MPEG-2 idinga cishe izikhathi ezine kuya kwezine ze-bitrate ye-H.264 yesithombe esifanayo, futhi okuqukethwe kwayo kuvame ukuxhuma, okubukeka kubukeka ku-displays amanje. MPG ithola wonke ama MPEG-2 amaphutha - i-bitrate enzima, ukuxhuma, akukho ngezansi okuthambile - kanye nokungqubuzana kwezinhlamvu ezimbili ezibanzi zefomethi eyodwa.

Yini i-codec yevidiyo i MPG isebenzisa?

Kuxhomekeka ku MPG 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.

Ingabe umsindo wami uzohlala ukhona MPEG kuya ku MPG?

Yebo. Uma MPEG ne MPG bebelana nge-codec yomsindo (isibonelo, zombili zifaka i-AAC), umsindo uphinde uhlukaniswe ngaphandle kokuphindeka kokufaka uphawu — okufanayo. Uma ama-codecs ahluka, umsindo uguqulwa ku-AAC / Opus / Vorbis ngokuya ngoMPG ibhokisi lokusekela. Umsindo we-multi-track (umbono, izilimi ezihlukile) ugcinwa.

Ingabe ngigcina ifreyimu yesiqalo uma ngiguqula MPEG ku MPG?

Ngokungajwayelekile yebo — i-24fps MPEG ihlala i-24fps ku-MPG; i-60fps MPEG ihlala i-60fps. Uma ufuna ukuguqula isilinganiso (isibonelo, i-interlaced 29.97 → progressive 30, noma i-60 → 30 uku-upload amalimi), isinqumo se-framerate siphatha 3:2 uku-pulldown, deinterlacing, ne-frame-blending ku-code pass efanayo.

Ingabe ubukhulu befayela bushintsha kanjani kusuka ku MPEG kuya ku MPG?

Same-codec re-mux (MPEG H.264 → MPG H.264 ushintsha isihlungi kuphela): ubukhulu obufana kakhulu. Ushintsho lwe-codec lungashintsha ngokujulile: H.264 → H.265 kufaka ihele ngengxenye ngaleyo khwalithi yokubuka efanayo; VP9 ifana kakhulu; AV1 ihlukanisa ezinye 20-30% kodwa ihamba kancane ukukopela.

Ingabe ihele MPG lizodlala ku-iPhone, Android, ne-Smart TVs?

MP4 / H.264 idlala ngokusemthethweni kuwo wonke amadivayisi amanje. MOV / H.264 idlala kumadivayisi we-Apple namanye ama-TV kodwa ahlala e-Android edlule. I-MKV idinga i-VLC ku-iOS. I-WebM iyisiphequluli sokuqala. Izinketho ezithuthukisiwe zifaka "ukuxhumana kwedivayisi" okusetshenzisiwe okukhetha i-MPG codec / ibhokisi eliphephile kakhulu lenjongo yakho. MPG yisibonisi sesoftware ye-DVD, ama-camcorders adala kanye nezixhobo zokusakaza ziyazi, ngakho ihlala isetshenziswa ezipayipini.

Ingabe kuthatha isikhathi esingakanani ukushintsha i-MPEG ividiyo yehora elilodwa ibe yi-MPG?

I-same-codec re-mux ifinyelela ngokushesha — 30 kuya ku-60 imizuzwana yefayela lehora elilodwa. I-codec ephelele iphinde ikhodeke isebenza ngokuyisisekelo 0.3-0.7x isikhathi somthombo ku-GPU yethu, ngakho-ke i-1-hour MPEG → MPG iphele ngemizuzu engu-18-40 ngokuya ngesinqumo ne-codec ethengiswayo.

Yini isixazululo esiphezulu esixhaswe yi MPEG kuya ku MPG?

Kuze ku-8K (7680×4320) kuma-premium plans. Ukuguquka okumahhala kufinyelela ku-4K (3840×2160) ngobukhulu befayela ngalinye. I-HDR metadata (HDR10, HDR10+, Dolby Vision uma ikhona) idluliselwa lapho ama-MPEG ne-MPG amabhokisi axhasa khona.

Ingabe i-MPEG yami yevidiyo ifihlakele ngesikhathi sokuguqulwa ku-MPG?

Yebo. Amafayela wevidiyo alayishwe phezulu aphathwa emisebenzini ehlukanisiwe, angeke abonelwe umuntu, angeke afakwe kwi-index, futhi asuswa ngaphakathi kwemizuzu yokuqedwa. Ifasitela lokugcinwa libhalwe ku /privacy/ futhi asishicileli lutho oluqeqeshiwe oluvela ku-uploads womsebenzisi.

Ingabe ngingakwazi ukugoqa, ukucisha, noma ukujikelezisa ngesikhathi sokuguqulwa MPEG kuya ku MPG?

Akunakwesinye isikhashana - sebenzisa /video-trim/ noma /video-cutter/ ukucisha kuqala, bese uqhuba MPEG → MPG ukuguqulwa. Ukucisha nokuguqula kushesha kunaku-encoding MPEG wonke nje ukususa isithombe esingasebenzisi.

MPEG

I-MPEG ifaka i-MPEG-1 ne-MPEG-2 izici zokuqala zevidiyo ezingaphansi kwe-Video CD ne-DVD, ezidlalwa kakhulu kodwa ezicindezelwe kakude yizici zamanje.
