VOB ukuba M4V Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-VOB ibe yi-M4V ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho ye VOB kwaye umguquli uqhube i-CRF-esekelwe kwi-encoding ephindayo ebhekisa kwi-visually-lossless M4V imveliso (i-CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne M4V isiqulathi-zifayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 yee-pipelines ezintsha. I-VOB igcina i-MPEG-2 video, AC-3 okanye i-PCM audio, kunye ne-DVD subpicture subtitle streams, ihlukaniswe ibe yi-1 GB yecandelo nge-DVD spec. Ngokusisiseko i-M4V yi-MP4 — H.264 okanye HEVC nge-AAC — ene-Apple FairPlay DRM ekhethiweyo kunye ne-iTunes isithuba se-metadata.

I-VOB yevidiyo yam ibonisa imigca ye-comb kwi-movement - iya kuthatha into kwi-M4V?

Iya kwenza ukuba awuyi-deinterlace, kwaye VOB imixholo ihlala i-interlaced ngenxa yokuba ifomati ivela kwixesha le-broadcast ne DVD. Iiframes ezi-interlaced zigcina iindawo ezimbini eziphakathi-ubukhulu eziqhotyoshelwe kwishumi elinesihlanu sesibini; kwifowuni eqhubekayo-yokukhangela okanye imboniselo efunda njenge-horizontal combing nantoni na ehambayo. Yenza ukhetho lwe-deinterlace kwaye i-encoder igubungela iindawo kwi-frames eziqhubekayo ezipheleleyo phambi kokubhala i M4V. I-VOB yi Video Object Container efumaneka kwi VIDEO_TS ulawulo lwe DVD nganye — i MPEG-2 inkqubo yokuhamba nge DVD-ekhethekileyo yokukhangela idata efakwe.

I-VOB yam yokurekhoda ihlukaniswe ibe ziinxalenye ezilinganisayo - ngaba i-M4V inemida efanayo?

Hayi, kwaye le yenye yezona zizathu zilungileyo zokushenxisa. I VOB isiqulathi siqulethe ifayile enye esebenzayo ethe tyaba eyenza ushicilelo olude okanye oluphezulu-bitrate luqhube ngokuthe ngqo, oko kukuthi, kutheni ushicilelo oludala lufika njengenxalenye1, ingxenye2, ingxenye3. M4V ayinalo umda ofanayo, ngoko ke iinxalenye zingadityaniswa kwakhona kwifayile enye eqhubekayo. I-VOB ihlukaniswe phakathi kweefayili, ingafihliwe nge-CSS, kwaye ihambisa iipakeji zokhangelo eziphazamisa abadlali abafunayo.

Kutheni le nto ifayili yam VOB ayiphumelelanga ukutshintshela kwi M4V?

Iifayile ze VOB zifihliweyo kwinqanaba le bitstream yindawo yokurhweba okanye isoftware ekhupha ifayile, kwaye umjelo ofihliweyo awunakucodwe sisi okanye ngantoni na ngaphandle kwesitshixo selayisensi. Iifayile ozirekhode, ozirhwebe ngaphandle okanye ozikhuphele ezantsi azikhuselwanga ziguqula ngokuqhelekileyo; ukuthengiswa kwelayisensi akuyi kwenza njalo, kwaye akukho mguquli uthembekileyo okwaziyo ukuthembisa okuthile.

Ingaba kufanelekile ukutshintsha i VOB yoshicilelo oludala ukuya kwi M4V?

Ukuba ufuna ukugcina into, ewe. VOB ibhekisa kuhlobo oludlulileyo lwezixhobo zevidiyo kwaye isoftware efunda i-video ihlala iphela kwifowuni, iziphene kunye nenkqubo yokusebenza. Ukushenxisa imifanekiso kwi M4V ngoku, ngelixa i-decoder ecocekileyo ikhona, kuhlukile phakathi kovimba onokuthi uvule kwiminyaka elishumi kunye noyena awukwazi. I-M4V igcina abaphawuli besiqendu, umsebenzi wobugcisa kunye nengoma yesihloko esingaphantsi kwisimo i-Apple TV app ilindeleyo, eyona MP4 iqhelekileyo ihlala ilahlekelwa yiyo.

Yeyiphi i-codec yevidiyo esetyenziswa yi-M4V?

Ixhomekeke kwi M4V isiqulathi seefayili. I-MP4 imiselwe ukuba ibe yi-H.264 ukuze ixhase ukudlala okubanzi phakathi kweefowuni, ii-browser, kunye ne-Smart TVs. I-MKV imiselwe ukuba ibe yi-H.265 / HEVC ukuze ilinganise nengxenye yobungakanani befayili kwinqanaba elifanayo lomgangatho. I-WebM imiselwe ukuba ibe yi-VP9. Iinketho eziphambili zibonisa ukhetho olucacileyo lwe-codec ukuba ufuna ukucima. M4V yi-Apple's MP4, esetyenziswa yi-iTunes ne-Apple TV app yefilimu kunye ne-TV.

Ingaba umculo wam wesandi uya kuqhubeka uguquka ukusuka kwi VOB ukuya kwi M4V?

Ewe. Xa VOB ne M4V zibelana nge-codec yesandi (umzekelo, zombini zithabatha i-AAC), isandi siphinda sixutywe ngaphandle kokubuyisela ukukhowuda - i-bit-identical. Xa ii-codecs zihlukile, isandi siguqulwa kwi-AAC / Opus / Vorbis kuxhomekeke ekubeni i-M4V ixhasa ntoni. I-audio enezithotho ezininzi (iingxelo, iilwimi ezitshintshiweyo) igcinwa.

Ndingagcina i-framerate yokuqala xa ndiguqula i-VOB ibe yi-M4V?

Ngokungagqibekanga ewe — i-24fps VOB ihlala i-24fps kwi-M4V; i-60fps VOB ihlala i-60fps. Ukuba ufuna ukuguqula umyinge (umzekelo, i-interlaced 29.97 → i-progressive 30, okanye i-60 → 30 yemida yokukhuphela), ukhetho lwe-framerate luphatha 3:2 ukutsala ezantsi, ukususa uthungelwano, kunye nokuqhekeka kwe-frame kwindlela efanayo yokufihla.

Ubungakanani befayili butshintsha njani ukusuka kwi VOB ukuya kwi M4V?

I-codec efanayo yokuphinda-phinda (VOB H.264 → M4V H.264 itshintsha kuphela isiqulathi seefayili): ubungakanani obufanayo. Utshintsho lwe-codec lunokutshintsha ngokumangalisayo: H.264 → H.265 luya kuquka ifayili kwinqanaba elifanayo lomgangatho wokubona; VP9 imalunga nokuthelekiswa; AV1 icima enye i-20-30% kodwa ihamba phantsi ukukopela.

Ingaba ifayili M4V iyadlala kwi-iPhone, Android, kunye neSmart TVs?

MP4 / H.264 idlala ngokusemthethweni kwisixhobo ngasinye esitsha. MOV / H.264 idlala kwizixhobo ze-Apple kunye neTV ezininzi kodwa hayi rhoqo kwi-Android edala. MKV ifuna i-VLC kwi-iOS. WebM ikwi-browser-first. Iinketho eziphambili ziquka "ukulungelelanisa isixhobo" esimiselweyo esikhetha i-M4V codec / isiqulathi esikhuselekileyo senjongo yakho. I-DRM-ikhuselwe i-M4V ithengiso ayikwazi ukutshintshwa yinto; kuphela iifayili ezikhuselweyo ze-M4V ziyatshintshwa, kwaye abadlali abangama-Apple bafuna uluhlu olubizwa kwakhona.

Ithatha ixesha elingakanani ukutshintsha i-VOB yevidiyo yeyure enye ibe yi-M4V?

I-Same-codec re-mux ikwindawo efutshane-imizuzu engama-30 ukuya kwengama-60 yefayili yeyure enye. I-codec epheleleyo ephinda-ikhowudi iqhuba malunga nexesha lomthombo we-0.3-0.7x kwi-GPU yethu, ngoko ke i-1-iyure VOB → M4V igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.

Yintoni ubukhulu bomfanekiso oxhaswayo kwi VOB ukuya kwi M4V?

Ukuza kuthi ga kwi-8K (7680×4320) kwi-premium plans. Ukuguqulwa simahla kugqityiwe kwi-4K (3840×2160) ngumda wobungakanani befayili nganye. I-HDR metadata (HDR10, HDR10+, Dolby Vision xa ikhona) iqhutywa apho zombini i VOB ne M4V iinqanawa zixhasa khona.

VOB

I-VOB (i-Video Object) yifomati yesikhongozeli esetyenziselwa ividiyo yeDVD. Ingaqulatha ividiyo, iaudio, izihlokwana, kunye neemenyu zokudlala kweDVD.
