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 video njenge-BMP imifanekiso?

Layisha phezulu i VOB kwaye umguquli ubonisa umkhethi wesakhelo-sokukhupha: isakhelo ngasinye se-Nth, iisakhelo kwixesha elikhankanyiweyo, okanye isakhelo ngasinye kwisiqingatha seyure. Isakhelo ngasinye esikhethiweyo sikhowudiwe njengefayili ye-BMP kwaye iseti epheleleyo ifakwe kwi-ZIP yovimba wokukhuphela. 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.

Kutheni iifayili zam ezikhuphiweyo zineemigca ethe tyaba ezidlula kuzo?

Kuba umthombo udityaniswe. VOB imixholo evela kwixesha le-DVD nele-broadcast igcina iindawo ezimbini zomphakamo wesiqendu kwiframe nganye, ithathwe kwishumi elinesixhenxe sesekondi, kwaye i-still ethe tyaba ibonisa zombini ezidityaniswe njenge-combing nantoni na ehambayo. Yenza u-deinterlacing phambi kokukhupha kwaye i-still nganye ikhiwa ukusuka kwi-frame eqhubekayo eyenziwe kwakhona.

Ingaba izihloko ezingaphantsi ziya kubonakala kwi BMP iifayili endizikhuphayo?

Ayinjalo ukuba ziyindawo ebonakalayo yokulandela umbhalo osezantsi ephepheni. I VOB igcina umbhalo osezantsi ephepheni njengendlela yabo yokuhamba kwaye umdlali uzoba ngaphezulu komfanekiso ngexesha lokudlala, ngoko ke isakhelo esikhowudiweyo umguquli ubhala ngaphandle njenge BMP inee-pixels ezicocekileyo ezantsi. Iisihloko ezisezantsi eziboshwe kwividiyo phambi kokuba ibe yi VOB ziyingxaki eyahlukileyo - ngoko ziyinxalenye yomfanekiso kwaye yonke i-frame ekhutshwe igcina ezi.

Ndingayitsala enye BMP ngaphandle kwesihloko ngasinye se VOB?

Ayiba iqhosha elinye, kodwa i VOB iyenza ibonakale icacile: iimpawu zesiqendu zigcinwa kwisiqulathi seefayili njengeziphawuli zexesha ezibizwa ngokuba ziphawuli zexesha, ngoko funda uluhlu lwesiqendu ngaphandle kwefayile kwaye ucofe ezixesha kwindawo yesiqendu sexesha. Ufumana enye BMP kwisiqendu ngasinye, ngokulandelana, eyiyo indlela eqhelekileyo yokwakha imifanekiso eqingqiweyo yoshicilelo olude. Amacebo angenamanqaku esiqendu ashiya ukukhetha imiboniso ngemehlo endaweni. I-VOB igcina yonke i-DVD yothutho olusebenzayo - ii-angles ezininzi, iilwimi ezininzi zesandi kunye nengoma yomxholo ophantsi zonke zihlala ngaphakathi.

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.

Uphi ubunzulu be-frame nganye ekhutshweyo BMP ephumayo?

Ubungakanani obufanayo ne-VOB ividiyo — i-1080p VOB ivelisa i-1920×1080 BMP ii-frames; i-4K VOB ivelisa i-3840×2160 BMP ii-frames. Sebenzisa uncedo lokuguqula ubungakanani emva kokukhupha ukuba ufuna ii-thumbnails ezincinci okanye ubungakanani be-social-media-crops.

Ndingayikhupha isakhelo ngasinye esitsha kwi VOB njenge BMP?

Ewe, kodwa uqaphele ngobalo lweefayili - i-30fps 1-minute VOB ivelisa i-1,800 BMP iifayili. Sizipakisha kwi-ZIP ngokuzenzekelayo. Kwiiclip ezide, ukhetho "1 ngomzuzwana" (iifayili ezi-60) okanye iziqinisekiso zexesha elikhankanyiweyo zinika isiphumo esiphathwayo.

Ingaba imifanekiso ekhutshweyo BMP iya kugcina umbala ophakamileyo VOB?

Ewe — umbala uguqulwa kwikhowudi nge-matrix esetyenziswa ngumboneleli VOB (BT.709 ye-HD, BT.2020 ye-4K HDR). Umboneleli we-HDR udweliswe nge-tone-mapping kwi-SDR xa uphuma kwi-BMP kuba i-BMP ifomati (PNG, JPG) ayikwazi ukugcina i-HDR pixel ranges ngokusemthethweni.

Lithini 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 egqithisileyo, ukukhupha i-PNG frame nganye ye-10-minute 1080p VOB kwenza ~50 GB ngokupheleleyo.

Ingaba i-BMP ekhutshweyo igcina i-EXIF metadata yekhamera?

Isiqulathi seefayili VOB asigcinanga i-EXIF yesakhelo ngasinye ngendlela ikhamera ehlala isebenza ngayo, ngoko ke ii-BMP iifayili ziphuma nge-EXIF engenanto. Sifaka `creation_time` indawo ebonisa umhla wokugqitywa kwesakhelo somthombo ukuze uphinde ulungelelanise i-bundle ngokulandelana kokuthatha.

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

Ukukhupha isakhelo kukhawuleza - ngokuqhelekileyo 20 ukuya kwi 30% yobude bomthombo kwindlela eqhelekileyo yokuhambisa. Imini emihlanu VOB → BMP iqela ligqiba malunga nemizuzu ngaphandle kokucinga ngobalo lwesakhelo, kuba ibhotile yengxowa yi BMP encoder, hayi i VOB demuxer.

Ndingazikhuphela iifayili kwixesha elikhankanyiweyo kwi VOB?

Ewe - ukhetho oluphambili luyakwamkela uluhlu oluhlukaniswe nge-comma lweziqinisekiso zexesha (umzekelo `00:01:23,00:05:00,00:10:42`) kwaye luvelisa ifayile enye BMP ngesatifiketi sexesha ngasinye. Isetyenziswa kwizifundo ezincinci zesahluko, iziganeko ezibhekisa kwimifanekiso, okanye izifundo ezide ezibonisa imifanekiso emifutshane.

VOB

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

BMP

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