VOB ukuba FLV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani ikhowudi i VOB ibe yi FLV ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho VOB kwaye umguquli uqhuba i-CRF-esekelwe kwakhona-ukukopela ukujolisa kwi-visually-lossless FLV imveliso (CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne FLV isiqulathi seefayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 ye-newer pipelines.

Yeyiphi i-codec yevidiyo esetyenziswa yi-FLV yemveliso?

Ixhomekeke kwi FLV isiqulathi seefayili. I-MP4 imiselwe ukuba i-H.264 ukuze ixhase ukudlala okubanzi phakathi kweefowuni, iibrowser, kunye neSmart TVs. I-MKV imiselwe ukuba i-H.265 / HEVC ukuze ijikeleze i-half of the file size at equivalent quality. I-WebM imiselwe ukuba i-VP9. Iinketho eziphambili zibonisa ukhetho olucacileyo lwe-codec ukuba ufuna ukucima.

Ingaba umculo wam wesandi uya kuqhubeka uguquka VOB ukuya FLV?

Yes. When VOB and FLV share an audio codec (e.g. both carry AAC), audio is re-muxed with no re-encode — bit-identical. When the codecs differ, audio is transcoded to AAC / Opus / Vorbis depending on what the FLV container supports. Multi-track audio (commentary, alternate languages) is preserved.

Ndingagcina i-framerate yokuqala xa ndiguqula i-VOB iye kwi-FLV?

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

Ingaba ubungakanani befayili butshintsha njani ukusuka kwi VOB ukuya kwi FLV?

I-codec efanayo yoku-mux (VOB H.264 → FLV H.264 itshintsha kuphela isiqulathi seefayili): ubungakanani obufanayo. Utshintsho lwe-codec lunokutshintsha ngokumangalisayo: H.264 → H.265 luya kuquka ifayile kwinqanaba elifanayo lomgangatho obonakalayo; VP9 imalunga nokuthelekiswa; AV1 iquka enye i-20-30% kodwa ihamba phantsi ukukopela.

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

MP4 / H.264 idlala ngokusemthethweni kwisixhobo ngasinye esitsha. MOV / H.264 idlala kwizixhobo zeApple 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-FLV codec / isiqulathi seefayili esikhuselekileyo esikhuselekileyo esilungele isiphelo sakho.

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

I-Same-codec re-mux ikwindawo efutshane-imizuzu engama-30 ukuya kwengama-60 yefayili yeyure enye. I-codec epheleleyo iqhuba ngokuthe ngqo kwi-0.3-0.7x yobude bomthombo kwi-GPU yethu, ngoko ke i-1-hour VOB → FLV igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.

Yintoni ubukhulu bokubonisa obuxhaswa yi VOB ukuya kwi FLV?

Ukuya kwi-8K (7680×4320) kwi-premium plans. Ukuguqulwa simahla kugqityiwe kwi-4K (3840×2160) ngobukhulu befayili nganye. I-HDR metadata (HDR10, HDR10+, Dolby Vision xa ikhona) iqhutywa apho zombini VOB ne FLV iziqulathi zixhasa khona.

Ingaba i-VOB yevidiyo yam ifihlakeleyo ngexesha liguqulwa li-FLV?

Ewe. Iifayili zevidiyo ezilayishwe phezulu ziqhubekekiswa kubasebenzi ababekwe ngokuzimeleyo, aziboniswanga ngumntu, azikho kwisicwangciso, zicinywa ngaphakathi kwemizuzu yokuphela. Ifestile yokugcina ibhalwe kwi /privacy/ kwaye asipapashi naziphi na iziqu zemfundo ezisuka kubasebenzisi abalayishwe phezulu.

Ndingayicima, ndiyibeke phantsi, okanye ndiyijikelezise ngexesha lokuguqulwa kwe VOB ukuya kwi FLV?

Ayikho kwinyathelo elifanayo — sebenzisa /video-trim/ okanye /video-cutter/ ukucima kuqala, emva koko qhuba u VOB → FLV uguqulelo. Ukudibanisa ukusika nokuguqula kukhawulezayo kune-re-encoding yonke i VOB ukushiya kuphela imifanekiso engasebenziswanga.

Kutheni le nto ifayili FLV imnyama xa kuthelekiswa nomcebo VOB?

I-bitrate-too-low imiselwe rhoqo. Ukunxulumana kwakhona ukusuka kwi-bitrate ephezulu VOB ukuya kwi-CRF emiselweyo FLV ikhupha kakhulu kwimifanekiso enamandla ehambayo. Nciphisa i-CRF ukuya kwi-16-18, okanye misela i-bitrate ecacileyo ehambelanayo ne-VOB, kwaye i-FLV ibuyisela ukubonakala kwayo.

Ingaba i-VOB ukuya kwi-FLV iguqulela iphatha izihloko ezingaphantsi?

Ewe - iingoma zesicatshulwa esifakwe ngaphakathi (mov_text kwi-MP4, SRT/ASS kwi-MKV) zigcinwa xa zombini VOB ne FLV iziqulathi zeefayili zixhasa. Iingoma zesicatshulwa ezitywiniweyo (ezitywiniweyo) zidlulisa ngokuzenzekelayo kuba zihlala kwisakhelo sevidiyo ngokwaso.

VOB

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

FLV

I-FLV (iVidiyo yeFlash) yifomati yesikhongozeli sevidiyo ephuhliswe nguAdobe. Isetyenziswa ngokuqhelekileyo ukusasazwa kwevidiyo kwi-intanethi kwaye ixhaswa yi-Adobe Flash Player.
