Indlela yokuguqula VOB ukuba BMP

Inyathelo 1: Layisha eyakho VOB iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho BMP iifayile

VOB ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-VOB ividiyo njenge-BMP imifanekiso?

Layisha phezulu i-VOB uze uvule izinto ezikhethwayo. Ukutsala isakhelo kuneendlela ezimbini: i-Frame eSingle igcina i-BMP enye ukusuka kwisekondi ongenisayo (umzekelo, 1, 5 okanye 10.5), kwaye Zonke ii-Frames zigcina zonke ii-frames zevidiyo njenge-BMP umfanekiso. Akukho ndlela ye-Nth-frame okanye ye-one-per-second. 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-BMP yi-Windows Bitmap, ifomati ye-raster egqityiweyo eyenziwe kwi-Windows ukusukela ngo-1985.

Ingaba izihloko zesihloko ziya kubonakala kwi-BMP iifayili endizikhupha?

Ayinjalo ukuba ziyindawo yomxholo ophambili. I VOB igcina umxholo ophambili njengothotho lwazo oluthile kwaye umdlali uzoba ngaphaya komfanekiso ngexesha lokudlala, ngoko isakhelo esikhowudiweyo umguquli ubhala ngaphandle njenge BMP inee-pixels ezicocekileyo ezantsi. Isihloko esiphantsi esikhutshwe kwividiyo phambi kokuba ibe yi VOB siyingxaki eyahlukileyo - ngoko ziyinxalenye yomfanekiso kwaye yonke isakhelo esikhutshwe sizigcina.

Ingaba iifayili BMP ziya kuba zikhulu kangakanani?

Ikhulu kunalo lonke ulindeleyo, kuba BMP igcina i-pixel nganye ngokuchanekileyo kunokuba ilinganise. I-1080p ihlala iwela ngaphantsi kwe-2-5 MB kwaye i-4K ihlala ngaphantsi kwe-6-15 MB, ngoko ke ukuphuma okude kudibanisa ngokukhawuleza. Oku kurhwebo oluchanekileyo xa imifanekiso i feed iqhubekeka, kwaye okubi xa zihamba ngqo kwiphepha le-web. I-BMP igcina imiqolo ye-pixel engacinezelwanga ngokupheleleyo enesihloko esincinci, oko kukuthi, yintoni eyenza kube lula ukuchaza ngeenkcukacha.

Kunye nobunzulu obunjani isakhelo ngasinye esikhutshwe BMP siphuma?

Ugqibo olufanayo njenge VOB ividiyo — i-1080p VOB ivelisa i-1920×1080 BMP iifayili; i-4K VOB ivelisa i-3840×2160 BMP iifayili. Sebenzisa uncedo lokuphinda ubungakanani emva kokukhupha ukuba ufuna iithumbnails ezincinci okanye ubungakanani bokusika i-social-media.

Ndingayikhupha isakhelo ngasinye esitsha kwi VOB njenge BMP?

Ewe, ngee-Frames zonke kukhetho lokuHlanganisa i-Frame, kodwa khangela ubalo: imizuzu emine ye-30 fps yevidiyo inika imifanekiso eyi-1,800 BMP. Ukuba uhlala phantsi, khetha i-Frame eSingle kwaye ufake umzuzwana ofuna ukuwufaka endaweni.

Ingaba imifanekiso ekhutshweyo BMP iya kugcina umbala ophakamileyo VOB?

I-HDR footage ayimaphulwanga umbala: i-frame nganye iguqulwa ukusuka kwi-VOB njengoko ikhowudiwe, ngoko i-frame ukusuka kwi-HDR VOB ingabonakali iphaphazela okanye icocwe ngaphandle njenge-BMP. Ividiyo eqhelekileyo (SDR) igcina imibala yayo.

Yintoni ubungakanani befayili yesakhelo esitshatweyo BMP?

Ixhomekeke kwisisombululo kunye ne BMP codec. I-1080p PNG frame ihlala i-2 ukuya kwi-5 MB; i-1080p JPG kwi-quality-85 i-200 ukuya kwi-500 KB; i-4K PNG i-6 ukuya kwi-15 MB. Kwimeko ebuhlungu, i-PNG frame nganye yokukhupha i-10-minute 1080p VOB ivelisa ~50 GB ngokupheleleyo.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka kwi VOB ukuya kwi BMP?

Oku kuxhomekeke kubungakanani nobude befayile. Amaxwebhu amancinci kunye nemifanekiso ihlala ilungile ngokukhawuleza. Iividiyo ezide zithatha ixesha elide, kuba iinguqulelo ezininzi zevidiyo ziphinde zikhowudi iframe nganye.

Ndingazikhupha iifayili kwixesha elikhankanyiweyo le VOB?

Enye ngaxeshanye. Isakhelo esipheleleyo sithatha ixesha elinye kwimizuzwana (umzekelo 83 ye 1: 23) kwaye sigcina esi sahlulo njenge BMP. Akukho ndawo yoluhlu lwexesha, ngoko ke qhuba uguqulelo kwakhona kwixesha elipheleleyo elingaphezulu.

Ingaba i-VOB yevidiyo yam ifihlakeleyo ngexesha lokukhupha isakhelo?

Ewe. Iifayile ezilayishwe phezulu ze VOB ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga. Ukukhuphela kunye nokuguqulwa kwe BMP kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.

Kutheni iifayili zam ezikhuphiweyo BMP zimnyama?

I-motion blur ihlala i-baked kwi-VOB source - ikhamera okanye into ehambayo xa i-frame ithathwa. Khetha i-timestamps ukusuka kwimeko-bume ehlala ikhona, okanye uthathe i-frames ezijikelezayo uze ukhethe ezicacileyo. I-pipeline ayiqwalaseli inkcukacha ezingakhoyo.

VOB

I-VOB yindawo yokugcina kwi-DVD yevidiyo, igcina i-MPEG-2 video, umsindo, kunye nesihloko, kwaye ingafihliwe.

BMP

Iifayile zeBMP zigcina imifanekiso kwifomathi yebitmap engacinezelwanga, nto leyo ebangela ukuba iifayile zibe nkulu kodwa zibe nomgangatho ogqibeleleyo.
