Indlela yokuguqula AVI ukuba BMP

Inyathelo 1: Layisha eyakho AVI 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

AVI ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-AVI ividiyo njenge-BMP imifanekiso?

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

Umfanekiso okhuphiweyo BMP uyaphuma njani kwisisombululo esipheleleyo?

Ugqibo olufanayo njenge AVI ividiyo — umthombo we-1080p uvelisa i-1920×1080 BMP iifayili; umthombo we-4K uvelisa i-3840×2160 BMP iifayili. Yenza ubungakanani kwakhona emva kokukhupha ukuba ufuna imifanekiso encinci ekhawulezayo.

Ndingayikhupha isakhelo ngasinye kwifayili AVI njenge BMP?

Ewe, kodwa uqaphele ngobalo lweefayili - i-30fps yevidiyo yemizuzu emi-1 ivelisa i-1,800 yeefayili. Sizifaka kwi-ZIP yovimba ngokuzenzekelayo. Kwimiqolo emide sebenzisa ukhetho "1 ngomzuzwana" (i-60 iifayili) okanye i-timestamps ekhethekileyo.

Ingaba imifanekiso BMP iya kugcina umbala AVI ophakamileyo?

Ewe - umbala uguqulwa kolunye ulwimi ngematriki efanayo esetyenziswa ngumboneleli AVI (BT.709 ye-HD, BT.2020 ye-4K HDR). Umboneleli we-HDR udweliswe ngetoni ye-map kwi-SDR xa ukhupha kwi-BMP (i-PNG / JPG ayikwazi ukugcina umthamo we-pixels ye-HDR ngokusemthethweni).

Yintoni ubungakanani befayili yesakhelo esitshatweyo BMP?

Ixhomekeke kwisisombululo kunye nokhetho lwe-codec. I-1080p PNG frame yi-2-5 MB; i-1080p JPG quality-85 frame yi-200-500 KB. Yiphindaphindwe nge-frame count ukuze ubungakanani be-ZIP — kwi-extreme, i-frame nganye yokukhupha i-10-min 1080p video kwi-PNG yi ~50 GB.

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

Isiqulathi seefayili AVI asigcinanga i-EXIF yesakhelo ngasinye ngendlela ikhamera ehlala isenza ngayo, ngoko ke ii-BMP iifayili ziphuma nge-EXIF engenanto. Sifaka `creation_time` indawo ebonisa i-source frame timestamp ukuze uphinde ulungelelanise i-bundle.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka kwi AVI ukuya kwi BMP?

Ukukhupha isakhelo kukhawuleza - ngokuqhelekileyo 20- 30% yobude bomthombo kwindlela eqhelekileyo yokuhambisa. Imizuzu emihlanu AVI → BMP iqela ligqiba malunga nemizuzu emi- 1 ngaphandle kokucinga ngobalo lwesakhelo, kuba ibhotile yengcambu yi BMP encoder, hayi i demuxer.

Ndingazikhupha njani iifayili kwixesha elikhankanyiweyo kwividiyo AVI?

Ewe - ukhetho oluphambili luyakwamkela uluhlu oluhlukaniswe nge-comma lweziqinisekiso zexesha (umzekelo `00:01:23,00:05:00,00:10:42`) kwaye luvelise i BMP ifayili nganye ngexesha elifanayo. Isetyenziswa kwizifundo ezincinci okanye iziganeko ezibhekisa kwimifanekiso.

Ingaba i-AVI yevidiyo yam ifihlakeleyo ngexesha lokukhupha isakhelo?

Ewe - imodeli yobumfihlo efanayo neyokuguqula yonke. Umthombo wevidiyo kunye neeframes ezikhuphiweyo ziqhubekeka kubasebenzi ababekwe ngokukodwa kwaye zicinywe kwimizuzu.

Kutheni iifayili zam ezikhuphiweyo BMP zimnyama?

I-motion blur ihlala ivela kumboneleli AVI (ikhamera yayihamba xa isakhelo sathathwa). Zama ukukhetha i-timestamp evela kwimiboniso eqinileyo, okanye uthathe ii-frames ezininzi ezidibeneyo uze ukhethe ezicacileyo. I-pipeline ayiqwalaseli ukubonakala.

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

Ayikho kutyibiliko olusisiseko - sebenzisa "1 ngomzuzwana" ukhetho njengolufutshane, emva koko ukhethe ngokubonakalayo iifayili zotshintsho lwendawo. Ukhuphelo olukhethekileyo lokufumana indawo lukwi-roadmap.

Ndingasebenzisa i-BMP isakhelo esikhutshweyo ngokurhweba?

Ewe, ixhomekeke kwilayisensi elawula umthombo AVI imixholo. Utshintsho lwefomati aluyi kuzisa nantoni na — siza kudibanisa akukho mqondiso wamanzi kwaye siza kuzisa nantoni na kwilayisensi kwi BMP imveliso.

AVI

Iifayile ze-AVI zinokuqulatha idatha yeaudio kunye nevidiyo, exhaswa kakhulu kodwa enobukhulu obukhulu beefayile.

BMP

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