Indlela yokuguqula MP4 ukuba BMP

Inyathelo 1: Layisha eyakho MP4 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

MP4 ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-MP4 video njengeemifanekiso ze-BMP?

Layisha phezulu ifayili ye MP4 kwaye umguquli ubonisa umkhethi wesakhelo: isakhelo ngasinye se-Nth, ii-frames kwi-timestamps ezicacileyo, 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?

Izinto ezibonakalayo ezilinganayo njengendawo yomthombo MP4 — ividiyo ye-1080p ivelisa ii-frames ezili-1920x1080 BMP, indawo yomthombo ye-4K ivelisa ii-frames ezili-3840x2160 BMP. Yenza ubungakanani kwakhona emva kokukhupha ukuba ufuna ii-thumbnails ezincinci (sinayo isixhobo se /image-resize/ sokwenza njalo).

Ndingayikhupha isakhelo ngasinye kwifayili ye MP4 njenge BMP?

Ewe, kodwa uqaphele ngobalo lwefayili - i-30fps 1-minute video ivelisa ii-frames ezili-1,800. Sizifaka kwi-ZIP ngokuzenzekelayo. Kwiiclip ezide "1 ngesekondi" ukhetho (i-frames ezili-60) okanye i-timestamps enegama lihlala lisetyenziswa ngakumbi kune-frame nganye.

Ingaba imifanekiso ye-BMP iya kugcina umbala we-MP4 HDR?

Amacebo e-HDR anama-tone-maps e-SDR xa ekhutshwa kwi-BMP (i-PNG / JPG ayikwazi ukugcina amanqanaba e-HDR pixels ngokusemthethweni). I-WebP / AVIF / TIFF BMP ingagcina i-gamut ebanzi ukuba i-BMP encoder ixhasa i-10-bit, ibonakaliswe kwiinketho eziphambili.

Lithini ubungakanani befayili yesakhelo esitsha se-BMP?

Kuxhomekeke kwisisombululo kunye ne-codec. I-1080p PNG frame yi-2-5 MB; i-1080p WebP frame kwi-quality 80 yi-80-200 KB; i-JPG quality-85 frame yi-200-500 KB. Yandisa ngokubala i-frame ukuze ubungakanani be-ZIP — i-PNG frame nganye ye-10-minute 1080p video imalunga ne-50 GB.

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

Isiqulathi seefayili MP4 asigcinanga i-EXIF yesakhelo ngasinye ngendlela eyenza ngayo ikhamera ehlala ihlala, ngoko ke iifayile ze BMP ziphuma nge-EXIF engenanto. Sifaka `creation_time` indawo ebonisa i-timestamp yesakhelo somthombo ukuze uphinde ulungelelanise i-bundle ngokulandelelana kwexesha.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka kwi-MP4 ukuya kwi-BMP?

Ukutsala isakhelo kukhawuleza - ngokuqhelekileyo 20-30% yobude bomthombo kwindlela eqhelekileyo yokuhambisa. Imizuzu emi-5 MP4 -> BMP iquka igqiba malunga nemizuzu emi-1 ngaphandle kokubala isakhelo, kuba ibhotile yengxowa yi BMP encoder hayi i-demuxer.

Ndingazikhupha iifayili kwixesha elikhankanyiweyo kwi-MP4?

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 ngesatifikethi sexesha. Isetyenziswa kwizifundo ezincinci okanye iziganeko zomfanekiso obhekisa kuwo umdlali.

Ingaba i-MP4 video yam ifihlakele ngexesha lokukhupha i-BMP?

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

Kutheni i-BMP isakhelo sam esikhutshweyo simnyama?

I-motion blur ihlala ivela kumgca ovela kumthombo MP4 — 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 ukususwa kwesahlulo-sendawo nganye?

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 MP4 imixholo. Utshintsho lwefomati aluyi kuzisa naziphi na izilumkiso — sisebenzisa akukho phawu lwamanzi, sifaka akukho kulandela, kwaye sicela akukho layisensi kwi-BMP imveliso.

MP4

Ifomathi yesikhongozeli seMP4 inokugcina ividiyo, iaudio, imibhalo engezantsi, kunye nemifanekiso kwifayile enye enoxinzelelo oluhle kakhulu.

BMP

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