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 njengeemifanekiso ze-BMP?

Layisha phezulu ifayili ye-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.

Umfanekiso okhuphiweyo we-BMP uphuma njani kwisisombululo esipheleleyo?

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

Ndingayikhupha isakhelo ngasinye kwifayili ye 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 ye-BMP iya kugcina umbala wokwahlulahlula i-AV1?

Ewe - umbala uguqulwa umbala nge-matrix efanayo esetyenziswa ngumbhali AV1 (BT.709 ye-HD, BT.2020 ye-4K HDR). Ababhali be-HDR babekwa kwi-tone-mapping ye-SDR xa bekhupha kwi-BMP (i-PNG / JPG ayikwazi ukugcina amanqanaba e-pixels e-HDR ngokusemthethweni).

Lithini ubungakanani befayili yesakhelo esitsha se-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 ikhamera ehlala isebenza ngayo, ngoko ke iifayile ze BMP ziphuma nge-EXIF engenanto. Sifaka `creation_time` indawo ebonisa i-timestamp yesakhelo somthombo ukuze uphinde ulungelelanise i-bundle.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka kwi-AV1 ukuya kwi-BMP?

Ukutsala isakhelo kukhawuleza — ngokuqhelekileyo 20-30% yobude bomthombo kwindlela eqhelekileyo yokuhambisa. I-5-imizuzu AV1 → BMP bundle igqiba malunga nemizuzu emi-1 ngaphandle kokuxhomekeka kubalo lwesakhelo, kuba i-bottleneck yi-BMP encoder, hayi i-demuxer.

Ndingazikhuphela njani ii-frames kwixesha elikhankanyiweyo 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 ye-BMP ngesatifiketi sexesha. Isetyenziswa kwizifundo ezincinci okanye iziganeko ezibhekisa kuzo.

Ingaba i-AV1 video yam ifihlakele ngexesha lokususa isakhelo?

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 kumgca ovela kumgca ovela kwi-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 imixholo. Utshintsho lwefomati aluyi kuzisa naziphi na izilumkiso — asiyi kudibanisa naziphi na izilumkiso ze-watermark kwaye asiyi kuzisa naziphi na izilumkiso zelayisensi kwimveliso ye BMP.

AV1

AV1 is a popular file format.

BMP

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