Indlela yokuguqula MPEG ukuba VOB

Inyathelo 1: Layisha eyakho MPEG iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho VOB iifayile

MPEG ukuba VOB Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-MPEG ibe yi-VOB ngaphandle kokulimala komgangatho?

Layisha phezulu i-MPEG ifayile kwaye umguquli wethu usebenzise i-CRF-esekelwe kwi-encoding ephindayo ebhekisa kwi-visually-lossless VOB output (CRF 18 ngokumiselweyo, ngaphantsi = enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne-VOB container — H.264 / H.265 / VP9 / AV1 njengoko kufanelekile.

Yeyiphi i-codec esetyenziswa yi-VOB output?

Oku kuxhomekeke kwisiqulathi seefayili. I-MP4 imiselwe ukuba ibe yi-H.264 (uxhaso lokudlala olubanzi kakhulu); i-MKV imiselwe ukuba ibe yi-H.265 yefayili encinci nge-~50% kwinqanaba elinye lomgangatho; i-WebM imiselwe ukuba ibe yi-VP9 okanye i-AV1 (ukusasazwa kwe-web ngaphandle kwe-royalty). Ungacima ukhetho lwe-codec kwizinto ezikhethwayo eziphambili phambi kokuba i-VOB iqhube ukuguqulwa.

Ingaba umculo wam wesandi uya kuhlala uphila MPEG ukuya VOB?

Ewe - isandi siphinda sixutywe xa i-MPEG ne-VOB zibelana nge-codec yesandi, okanye ziphinde zikhowudiswe kwi-AAC / Opus / Vorbis ngokuxhomekeke kwinto exhaswa yi-VOB. Isandi esininzi (iingxelo, iilwimi ezitshintshiweyo) sigcinwa kwiziqulathi ezixhasayo (MKV, WebM, MP4).

Ndingagcina i-framerate eqhelekileyo isuka kwi-MPEG ukuya kwi-VOB?

Ngokungagqibekanga i-framerate ayitshintshwanga (MPEG 24fps ihlala i-24fps kwi-VOB). Ukuba ufuna ukuyitshintsha (umzekelo, i-interlaced 29.97 ukuya kwi-progressive 30fps) ukhetho lwe-framerate luphatha 3:2 ukutsala ezantsi nokungaqhekezi kwindlela efanayo — akukho sibini sokukhupha ikhowudi esifunekayo.

Yintoni ubungakanani befayili obuhlukileyo phakathi kwe-MPEG ne-VOB?

I-codec efanayo ephinda-i-muxes (H.264 zombini MPEG kunye ne VOB) ivelisa ubungakanani obufanayo. Iinguqu ze-codec zingatshintsha izinto ngokumangalisayo: H.264 -> H.265 ihlala iquka ifayile kwinqanaba elifanayo lomgangatho wokubona; H.264 -> VP9 imalunga nokuthelekiswa; AV1 ngoku incinci ngexabiso lexesha elicocekileyo lokukopela.

Ingaba ifayili ye VOB iya kudlala kwi-iPhone / Android / Smart TV?

MP4 / H.264 idlala naphi na ngokusemthethweni. MOV / H.264 idlala kwizixhobo ze-Apple kunye ne-Smart TVs ezininzi kodwa hayi kwi-Android edala. MKV ifuna i-VLC kwi-iOS. I-WebM idlala kwi-browser kodwa hayi kwi-Smart TV apps ezininzi. I-"isixhobo sokuhambelana" esimiselweyo kwiinketho eziphambili ikhetha i-codec / i-container ekhuselekileyo yenjongo yakho.

Ithatha ixesha elingakanani ukutshintsha ifayili yeyure enye ye-MPEG ibe yi-VOB?

Ixhomekeke kutshintsho lwe-codec. I-codec efanayo yoku-multiplex: imizuzwana eyi-30-60 (akukho kuphinda-kukhowude). Ukuphinda-khowude kwi-codec eyahlukileyo: ngokuqhelekileyo 0.3-0.7x ixesha lomthombo kwi-GPU yethu ye-pipeline, ngoko ke i-1-iyure MPEG -> VOB igqiba kwimizuzu eyi-18-40; i-AV1 yoku-khowuda ihamba 2-3x ngaphantsi.

Yintoni ubukhulu bokubonisa obuxhaswa yi-MPEG ukuya kwi-VOB?

I-HDR metadata (HDR10, Dolby Vision) igcinwa apho zombini i-MPEG kunye ne-VOB imixholo kunye nee-codecs zixhasa khona; amacebo e-SDR ahlala e-SDR.

Ingaba i-MPEG video yam ifihlakele ngexesha lokuguqulwa kwe-VOB?

Ewe - iifayile zevidiyo ezilayishwe phezulu ziqhubekekiswa kubasebenzi ababekwe ngokuzimeleyo kwaye zicinywe kwimizuzu yokuphela. Akukho kuhlaziyo lomuntu, akukho kugcina ngaphezulu kwefestile ebhalwe phantsi. Bona /privacy/.

Ndingatywina okanye ndityhefe ngexesha lenyathelo MPEG ukuya kwi-VOB?

Ayikumgangatho ofanayo — sebenzisa /video-trim/ okanye /video-cutter/ ukucima i-MPEG kuqala, emva koko ufolo i-MPEG -> VOB uguqulelo. Ukuguqula-ukusika-ukuguqula kukhawulezayo kune-ukubuyisela kwikhowudi ifayile yonke ukucima kuphela i-output.

Kutheni i-VOB ifana ne-MPEG?

I-bitrate-too-low imiselwe rhoqo. Ukunxulumanisa kwakhona i-bitrate ephezulu MPEG kwi-bitrate ephantsi VOB kwi-CRF emiselweyo icinezela imiboniso enezithuthi ezinzima kakhulu. Thobela i-CRF ezantsi ukuya kwi-16-18 (okanye misela i-bitrate ecacileyo) kwaye uphinde uqhube ukubuyisela umgangatho.

Ingaba i-MPEG ukuya kwi-VOB converter ixhasa izihloko zesiphelo?

Ewe - iingoma zesihloko esingaphantsi ezifakwe ngaphakathi (mov_text kwi-MP4, SRT / ASS kwi-MKV, WebVTT kwi-WebM) zigcinwa xa zombini i-MPEG kunye ne-VOB iziqulathi zixhasa ezo. Iingoma zesihloko ezitywiniweyo (ezinzima) zidluliswa ngokuzenzekelayo kuba ziyinxalenye ye-pixel data.
