VOB ukuba MPG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-VOB ibe yi-MPG 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-MPG 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. Okuqulethwe yi-MPEG-1 okanye i-MPEG-2 ividiyo ene-MP2 umsindo; ukudibanisa nokwakhiwa kwe-GOP kufana ne-.mpeg ifayili.

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

Hayi, hayi kule phepha. VOB ne MPG 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-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-MPG ifana nenkqubo ye-MPEG ejikelezayo njenge-.mpeg — uluhlu lweeleta ezintathu luyi-DOS-era truncation, hayi ifomati eyahlukileyo.

I-VOB yam yokurekhoda ihlukaniswe ibe ziinxalenye ezilinganisayo - ngaba i-MPG 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. MPG 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.

Yintoni eyenza i-subtitle tracks kwifayili yam VOB?

Zilahliwe. i-MPG ayinalo unikezelo lwesicatshulwa esicocekileyo sokugcina, kwaye umguquli awunakubathwala kwimifanekiso okanye awuzikhupheli njengefayili eyahlukileyo. Ukuba ufuna, khupha isicatshulwa kwi-.srt ifayile ngesixhobo se-desktop njenge-ffmpeg okanye i-MKVToolNix phambi kokuguqula, kwaye ufake loo fayili ecaleni kwe-MPG kumdlali wakho. MPG ifumana yonke i MPEG-2 imida - i-bitrate enzima, uthungelwano, akukho sihloko esicocekileyo - kunye nokungaqhelekanga kweendawo ezimbini zokukhupha ifomati enye.

Kutheni le nto ifayili yam VOB ayiphumelelanga ukutshintshela kwi MPG?

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

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.

Yeyiphi i-codec yevidiyo esetyenziswa yi-MPG?

Oku kuxhomekeke kwi-MPG 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 VOB ukuya kwi MPG?

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

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

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.

Ingaba ifayili MPG 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. MPG yi DVD yoshicilelo lwesoftware yolubanzi, i-camcorders edala kunye nezixhobo zokusasaza ukutya ziyazi, ngoko ihlala isetyenziswa kwezi ntambo.

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

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.

VOB

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