Indlela yokuguqula AV1 ukuba BMP

Inyathelo 1: Rhweba ngaphakathi AV1 iifayili usebenzisa iqhosha phezulu okanye nge shift nendawo.

Inyathelo 2: Nqakraza kwiqhosha 'Uguqulo' ukuqala uguqulo.

Inyathelo 3: Gcina ifayile yakho eguqulweyo BMP iifayile

AV1 ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-AV1 video njenge-BMP imifanekiso?

Layisha phezulu ifayili AV1 kwaye umguquli ubonisa umkhethi wesakhelo-sokukhupha: isakhelo ngasinye se-Nth, ii-frames kwi-timestamps ezichaziweyo, okanye i-frame enye ngesekondi. Isakhelo ngasinye esikhethiweyo sikhowudiwe njengefayili ehlukileyo ye BMP kwaye sidityaniswe njenge-ZIP yokukhuphela ezantsi.

Umfanekiso okhuphiweyo BMP uphuma njani kwisisombululo esipheleleyo?

Ubungakanani obufanayo njenge-AV1 ividiyo — umthombo we-1080p uvelisa i-1920×1080 BMP ii-frames; umthombo we-4K uvelisa i-3840×2160 BMP ii-frames. Yenza kwakhona ubungakanani emva kokukhupha ukuba ufuna ii-thumbnails ezincinci.

Ndingayikhupha isakhelo ngasinye kwifayili AV1 njenge BMP?

Ewe, kodwa uqaphele ngobalo lwefayili - i-30fps 1-minute video ivelisa ii-frames ezili-1,800. Sizifaka kwi-ZIP archive ngokuzenzekelayo. Kwiiclip ezide sebenzisa ukhetho "1 ngesekondi" (i-frames ezili-60) okanye iziqinisekiso zexesha ezikhethekileyo.

Ingaba imifanekiso BMP iya kugcina umbala ophakamileyo AV1?

Ewe - umbala uguqulwa kwikhowudi nge-matrix efanayo esetyenziswa ngumboneleli AV1 (BT.709 ye-HD, BT.2020 ye-4K HDR). Umboneleli we-HDR udweliswe nge-tone-map kwi-SDR xa ukhupha kwi-BMP (i-PNG / JPG ayikwazi ukugcina amanqanaba e-pixels e-HDR ngokusemthethweni).

Lithini ubungakanani befayili yesakhelo esitshatweyo BMP?

Kuxhomekeke kwisisombululo kunye nokhetho lwe-codec. I-1080p PNG frame yi-2-5 MB; i-1080p JPG quality-85 frame yi-200-500 KB. Yandisa ngokubala i-frame ukuze ubungakanani be-ZIP — kwinqanaba eliphezulu, ukususwa kwe-frame nganye ye-10-min 1080p video kwi-PNG yi ~50 GB.

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

Isiqulathi seefayili AV1 asigcinanga i-EXIF yesakhelo ngasinye ngendlela eyenza ikhamera ehlala ihlala, ngoko ke ii-BMP iifayili ziphuma nge-EXIF engenanto. Sifaka `creation_time` indawo ebonisa umhla wokugqitywa kwesakhelo somthombo ukuze uphinde ulungelelanise i-bundle.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka ku AV1 ukuya ku BMP?

Ukukhupha isakhelo kukhawuleza - ngokuqhelekileyo 20- 30% yobude bomthombo kwindlela eqhelekileyo yokuhambisa. Imizuzu emi- 5 AV1 → BMP iquka igqiba malunga nemizuzu emi- 1 ngaphandle kokubala isakhelo, kuba ibhotile yengxowa yi BMP encoder, hayi i demuxer.

Ndingazikhuphela njani ii-frames kwi-timestamp ekhankanyiweyo kwi-AV1 video?

Ewe - ukhetho oluphambili luyakwamkela uluhlu oluhlukaniswe nge-comma lweziqinisekiso zexesha (umzekelo `00:01:23,00:05:00,00:10:42`) kwaye luvelisa ifayili enye BMP ngesatifiketi sexesha ngasinye. Isetyenziswa kwizifundo ezincinci okanye iziganeko ezibhekisa kuzo.

Ingaba i-AV1 yevidiyo yam ifihlakeleyo xa ikhutshwa i-frame?

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngasinye. Ividiyo yombhalo kunye neefreyimu ezikhuphiweyo ziqhubekekiswa kubasebenzi ababekwe ngokuzimeleyo kwaye zicinywe kwimizuzu.

Kutheni i-BMP isakhelo sam esikhutshweyo simnyama?

I-motion blur ihlala ivela kumboneleli AV1 (ikhamera yayihamba xa isakhelo sathathwa). Zama ukukhetha i-timestamps ukusuka kwimiboniso ehlala ikhona, okanye uthathe ii-frames ezininzi ezibekwe phantsi uze ukhethe ezicacileyo. I-pipeline ayiqwalaseli ukubonakala.

Ingaba le sixhobo sixhasa ukutsala isakhelo esinye ngasinye kutshintsho lwendawo yomboniso?

Akukho kutyibiliko olusisiseko - sebenzisa ukhetho "1 ngomzuzwana" njengokwenkxaso, emva koko ukhethe ngokubonakalayo iifayili zotshintsho lwendawo. Umqokeleli wokufumana indawo okhethekileyo ukwi-roadmap.

Ndingasebenzisa i-BMP isakhelo esikhutshweyo ngokurhweba?

Ewe, ngokuxhomekeke kwilayisensi elawula umthombo AV1 umxholo. Utshintsho lwefomati aluyi kuzisa naziphi na izilumkiso — siza kudibanisa akukho phawu lwamanzi kwaye siza kuzisa naziphi na izilumkiso kwi BMP imveliso.

AV1

AV1 yi-video codec ekhululekileyo engekho mthethweni ebetha i-H.264 ne-HEVC kubungakanani befayili, ngexabiso lokunxulumana okucothayo kakhulu.

BMP

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