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

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

VOB ukuba TIFF Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu i-VOB uze uvule izinto ezikhethwayo. Ukutsala isakhelo kuneendlela ezimbini: i-Frame eSingle igcina i-TIFF enye ukusuka kwisekondi ongenisayo (umzekelo, 1, 5 okanye 10.5), kwaye Zonke ii-Frames zigcina zonke ii-frames zevidiyo njenge-TIFF 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-TIFF yifomati yefayili yomfanekiso ophawulweyo ukusukela ngo-1986, kwaye yifomati yokukhangela, yoshicilelo kunye nokugcina iinjineli ezimiselwe.

Ingaba izihloko zesihloko ziya kubonakala kwi-TIFF 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 TIFF inee-pixels ezicocekileyo ezantsi. Isihloko esiphantsi esikhutshwe kwividiyo phambi kokuba ibe yi VOB siyingxaki eyahlukileyo - ngoko ziyinxalenye yomfanekiso kwaye yonke isakhelo esikhutshwe sizigcina.

Ingaba i-TIFF ixhasa ukubonakaliswa ngokucacileyo?

Ifomati isebenza, kodwa umbhali akafuni i-alpha ukunika - ii-frames zevidiyo kunye neephepha ezibonisiweyo zicacile ngokupheleleyo, ngoko ke zonke ii-pixels zifika ziqinile. Isiqhagamshelanisi se-alpha sihlala sisetyenziswa emva koko: kuthetha ukuba ungacima into ephuma kwi-TIFF kamva ngaphandle kokuguqula i-format kwakhona. I-TIFF iphatha i CMYK, ubunzulu be-16-bit, i-ICC efakwe ngaphakathi kunye namaxwebhu amaphepha amaninzi, eyona nto ishicilela kwaye ifuna uthungelwano lomsebenzi wokugcina.

Ingaba iifayili TIFF ziya kuba zikhulu kangakanani?

Ikhulu kunalo lonke ulindeleyo, kuba TIFF 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-TIFF yindawo yokugcina engaphezulu kwe-codec: inokuphatha i-data engacinezelwanga, i-LZW, i-ZIP okanye nakwi-JPEG, ukuya kuthi ga kwi-32 bits kwisiqhagamshelanisi ngasinye, ngeephepha ezininzi kwifayili enye.

Kunye nobunzulu obunjani isakhelo ngasinye esikhutshwe TIFF siphuma?

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

Ndingayikhupha isakhelo ngasinye esitsha kwi VOB njenge TIFF?

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

Ingaba imifanekiso ekhutshweyo TIFF 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-TIFF. Ividiyo eqhelekileyo (SDR) igcina imibala yayo.

Yintoni ubungakanani befayili yesakhelo esitshatweyo TIFF?

Ixhomekeke kwisisombululo kunye ne TIFF 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 TIFF?

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 TIFF. 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 TIFF kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.
