MPG ukuba VOB Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho ye-MPG 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-VOB output ifumana i-codec exhasa isiqulathi seefayili: H.264 ye-MP4, MOV ne-MKV, VP9 ye-WebM. Okuqulethwe yi-MPEG-1 okanye i-MPEG-2 ividiyo ene-MP2 umsindo; ukudibanisa nokwakhiwa kwe-GOP kufana ne-.mpeg ifayili. 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.

Ingaba i MPG ingaguqulwa ibe yi VOB ngaphandle kokubuyisela umbhalo ofihlakeleyo wevidiyo?

Hayi, hayi kule phepha. MPG ne VOB zisebenzisa ukwakhiwa okuphantsi okufanayo, kodwa umguquli uphinde ukhowudi ividiyo kule par ngaphandle kokukopa umsinga, ngoko kuthatha ixesha elide kunesiqulathi sotshintsho kwaye umfanekiso ucinezelwe kwakhona. Khetha Ubunjani obuphezulu phantsi koBunjani ukugcina inkcukacha ezininzi. I-MPG ifana nenkqubo ye-MPEG ejikelezayo njenge-.mpeg — uluhlu lweeleta ezintathu luyi-DOS-era truncation, hayi ifomati eyahlukileyo. 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.

Ndingazifaka njani izihloko ezingaphantsi ezikhethiweyo xa ifayili ikwi VOB?

Ewe. MPG ayinayo i-soft-subtitle track esetyenziswayo, ngoko ke i-subtitles ye MPG imixholo yakufuneka ikhutshwe kumfanekiso okanye ithunyelwe njengefayili ye-sidecar eyahlukileyo. VOB ithatha i-subtitles njengemjelo yabo ekhethiweyo, ngoko ke emva kokuguqula ungadibanisa i-SRT track imboniso ingatshintshwa, itshintshwe okanye iphinde iguqulwe.

Ingaba i VOB inkxaso yamachaphaza ophawu anjengoko MPG ayizange ikwenze?

Iyenza. VOB igcina izihloko njenge metadata yesiqulathi seefayili, ngoko ushicilelo olude lunokuqhubela phambili ngecandelo endaweni yokucoca ibar yokuqhubekeka. MPG ayinanto yokubeka loo lwazi, ngoko i VOB eguqulweyo iqala ngaphandle kwezihloko; yongeza abaphawuli emva kwesixhobo njenge MKVToolNix okanye ffmpeg. I-VOB igcina yonke i-DVD yothutho olusebenzayo - ii-angles ezininzi, iilwimi ezininzi zesandi kunye nengoma yomxholo ophantsi zonke zihlala ngaphakathi.

Ingaba kukho incopho eguqula phakathi kwefomati ezimbini ezidala njenge MPG ne VOB?

Ukuba nje inxalenye ekhethekileyo yezixhobo ifuna injongo. Iifomati zombini zivela kwixesha elifanayo elingaphambili le-H.264, ngoko akukho kuguqulelo luthenga ukusetyenziswa kakuhle, umgangatho okanye uqinisekiso lwexesha elizayo - luthenga ukulungelelaniswa nesixhobo esithile. Ukuba injongo kukugcina imifanekiso esetyenziswa ixesha elide, guqula kwicontainer yangoku endaweni ye-sideways. MPG ifumana yonke i MPEG-2 imida - i-bitrate enzima, uthungelwano, akukho sihloko esicocekileyo - kunye nokungaqhelekanga kweendawo ezimbini zokukhupha ifomati enye. I-VOB ihlukaniswe phakathi kweefayili, ingafihliwe nge-CSS, kwaye ihambisa iipakeji zokhangelo eziphazamisa abadlali abafunayo.

Yeyiphi i-codec yevidiyo esetyenziswa yi-VOB?

Oku kuxhomekeke kwi-VOB 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 ukusuka kwi MPG ukuya kwi VOB?

Ewe, umculo ophambili wesandi udlula, uphinde ukhowudiwe kwi-codec i-VOB 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-MPG ibe yi-VOB?

Ewe. Umyinge we-frame igcinwa ngaphandle kokuba uyitshintshe: i-24 fps MPG ihlala i-24 fps kwi-VOB. 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.

Ubungakanani befayili butshintsha njani ukusuka kwi MPG ukuya kwi VOB?

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-MPG 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.

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

MP4 kunye H.264 idlala kwi-smartphone, i-browser kunye ne-TV. MOV kunye ne-H.264 idlala kwi-Apple kunye ne-TV ezininzi kodwa hayi kwi-smartphone ye-Android edala. MKV ifuna i-app efana ne-VLC kwi-iOS, kwaye i-WebM ihlala ekhaya kwii-browser. Akukho sixhobo esimiselweyo kule phepha, ngoko khetha ifomati efanelekileyo yesixhobo sakho esixhasayo.

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

Akukho xesha elimiselweyo: lixhomekeke kubungakanani, ubungakanani obucacileyo kunye nohlobo lwenjongo. Uguqulelo luyasebenza kwiseva yethu ye-CPUs kunye nesoftware encoders; akukho GPU ekhawulezayo. MKV ukuya MP4 okanye MOV ngemimiselo emiselweyo ikopa umsinga wevidiyo kwaye ikhawuleza kakhulu. Ukuphinda uguqulele kwi-H.264 kuthatha ixesha elide, kwaye i-WebM (VP9) yinjongo ekhawulezayo, iphinda ikhawuleze kakhulu kune-H.264 kwiimvavanyo zethu.

Yintoni ubukhulu bomfanekiso oxhaswayo kwi MPG ukuya kwi VOB?

Umguquli awunaso isiphelo somfanekiso ocacileyo; umda ubungakanani bokukhuphela obuvunyelweyo kwinkqubo yakho, kwaye umfanekiso ocacileyo uhlala njengonjalo ngaphandle kokuba ukhetha i-1080p, 720p okanye 480p. Akukho HDR uqhubekeko okanye umbala wokumaphu. Xa umsinga wevidiyo ukopiwe (MKV ukuya kwi MP4 okanye MOV ngemimiselo emiselweyo), i-HDR10 idlula ngaphandle kokuxhathisa. Ukuphinda ukhowudi ukhupha i-HDR10 ulawulo lwemetadata, kunye noBunjani, Ubunjani okanye i-Frame Rate ucwangciso ezinye iipere zikhupha ividiyo kumbala we-8-bit, ngoko i-HDR MPG ingabonakalisa i-washed out.

MPG

IMPG lulwandiso lwefayile yeMPEG-1 okanye MPEG-2 iifayile zevidiyo. Isetyenziswa ngokuqhelekileyo ukudlala ividiyo kunye nokusasazwa.

VOB

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