VOB ukuba MP4 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani ikhowudi i VOB ibe yi MP4 ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho ye-VOB kwaye umisele Umgangatho kwiNtlonipho eNkulu kwizinto ezikhethwayo zokuguqula. Oku kuphinda kuqulethe ividiyo kwisicwangciso esiphezulu somgangatho (CRF 18 ye-H.264 ne-VP9 output), egcina inkcukacha ezininzi kwixabiso lefayili enkulu. Okumiselweyo, Okuthe nkqo, sebenzisa isicwangciso esiqhelekileyo. I-MP4 output ifumana i-codec exhasa isiqulathi seefayili: H.264 ye-MP4, MOV ne-MKV, VP9 ye-WebM. 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. I-MP4 eninzi eluhlaza yi-H.264 yevidiyo enesandi se-AAC; isiqulathi seefayili sigcina ngokusemthethweni i-HEVC, i-AV1 ne-VP9.

I-VOB yevidiyo yam ibonisa imigca ye-comb kwi-movement - iya kuthatha into kwi-MP4?

Ewe. imixholo ye VOB ihlala idityaniswa, kuba ifomati ivela kwixesha le broadcast ne DVD, kwaye lo mguquli unenketho engadityaniswanga, ngoko ucombing uhambisa kwi MP4. Ukuba kubaluleke, dibanisa i VOB kuqala kwisixhobo se desktop njenge HandBrake okanye ffmpeg (icebo lokucoca ulwelo le yadif). 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-MP4 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. MP4 ayinalo umda ofanayo, ngoko ke iinxalenye zinokudityaniswa kwakhona kwifayile enye eqhubekayo. I-VOB ihlukaniswe phakathi kweefayili, ingafihliwe nge-CSS, kwaye ihambisa iipakeji zokhangelo eziphazamisa abadlali abafunayo.

I VOB yam inezinto ezininzi ezidlala umculo - ngaba zonke ziya kuhlala zikhona kwi MP4?

Hayi. Umguquli ugcina umculo omnye wesandi, owona mculo unamandla kakhulu (oqhelekileyo uthelekiso oluphambili), kwaye ukhupha onke; akukho mmiselo wokukhetha omnye ohlukileyo. Ukugcina omnye umculo, yenza kwakhona i-VOB ngomsebenzi wokuqala (i-VLC okanye i-ffmpeg ingakwenza oku), emva koko uyiguqule. I-VOB igcina yonke i-DVD yothutho olusebenzayo - ii-angles ezininzi, iilwimi ezininzi zesandi kunye nengoma yomxholo ophantsi zonke zihlala ngaphakathi. I-MP4 ixhasa kuphela ifomati enye ethandwayo yesihloko esingaphantsi (mov_text), nesandi esininzi esingenakuthembeka ngaphandle kwabadlali be-desktop.

Kutheni le nto ifayili yam VOB ayiphumelelanga ukutshintshela kwi MP4?

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

Ingaba i MP4 iyadlala kwisikhangeli xa i VOB ayiyidlala?

Ewe, kwaye oko kuqhelekileyo isizathu esipheleleyo sokuguqula. A VOB efakwe kwiphepha le web okanye ibonisa umdlali olahlwayo okanye iforce ulwaleko, kuba ibrowser ayithuthinga i decoder kuyo. MP4 idlala kwilayini esuka kwi HTML5 eqhelekileyo isixhobo sevidiyo ngaphandle koplugin kwaye akukho sicelo sengaphandle. I-MP4 yindawo ekhuselekileyo yokunikezelwa kweenkqubo ezifumanekayo - yonke ifowuni, ibrowser, i-console, umhleli kunye neSmart TV eyenziwe kwiminyaka elishumi edlulileyo idlala ngaphandle kwesoftware engaphezulu.

Ingaba kufanelekile ukutshintsha i VOB yoshicilelo oludala ukuya kwi MP4?

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 MP4 ngoku, ngelixa i-decoder ecocekileyo ikhona, kuhlukile phakathi kovimba onokuthi uvule kwiminyaka elishumi kunye noyena awukwazi.

Yeyiphi i-codec yevidiyo esetyenziswa yi-MP4 yemveliso?

Oku kuxhomekeke kwi-MP4 container. I-MP4, MOV ne-MKV output isebenzisa i-H.264, edlala kwifowuni yonke, umkhangeli zincwadi neTV. I-WebM output isebenzisa i-VP9. I-AVI, WMV ne-MPEG output isebenzisa ii-codecs ezidala ezo fomati zaphuhliswa kuzo.

Ingaba umculo wam wesandi uya kuqhubeka uguquka VOB ukuya MP4?

Ewe, umculo ophambili wesandi udlula, uphinde ukhowudiwe kwi-codec i-MP4 idlala, umzekelo i-AAC kwi-MP4 ne-MOV okanye i-Opus kwi-WebM. Iindawo ezininzi zokuguqulela zigcina kuphela umculo omnye (onye oneendawo ezininzi), ngoko ke iilwimi ezitshintshiweyo kunye nolwazi olusisiseko lulahliwe. I-MP4 ukuya kwi-MOV, ne-AVI, WMV, MPEG, FLV, VOB okanye M4V ukuya kwi-MKV, gcina wonke umculo wesandi.

Ndingagcina i-framerate yokuqala xa ndiguqula i-VOB iye kwi-MP4?

Ewe. Umyinge we-frame igcinwa ngaphandle kokuba uyitshintshe: i-24 fps VOB ihlala i-24 fps kwi-MP4. Ummiselo we-Frame Rate unokuguqula ibe yi-60, 30 okanye i-24 fps. Itshintsha kuphela umyinge; ayitshintshi i-interlace yevidiyo okanye isuse i-3:2 pulldown.

Ingaba ubungakanani befayili butshintsha njani ukusuka kwi VOB ukuya kwi MP4?

Oku kuxhomekeke ekubeni kwenzeka ntoni kwividiyo. I-MKV ukuya kwi-MP4 okanye i-MOV ngemimiselo emiselweyo ikopa umsinga wevidiyo ungatshintshwanga, ngoko ubungakanani buhlala bufutshane nomcebo. Ezinye iipere ziphinda ziyikhowudi: i-VOB ene-bitrate ephezulu ihlala iphuma incinci, ngelixa enye ekhoyo icinezelwe kakhulu ikhula. Ifayile encinci phantsi koBunjani inika imveliso encinci, kwaye i-H.265 kuMmiselo weCodec (MP4, MOV ne-MKV) ihlala incinci kune-H.264 kwi-quality efana nayo kodwa idlala kwizixhobo ezincinci.
