MPG ukuba PNG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-MPG video njenge-PNG imifanekiso?

Layisha phezulu i-MPG uze uvule izinto ezikhethwayo. Ukutsala isakhelo kuneendlela ezimbini: i-Frame eSingle igcina i-PNG enye ukusuka kwisekondi ongenisayo (umzekelo, 1, 5 okanye 10.5), kwaye Zonke ii-Frames zigcina zonke ii-frames zevidiyo njenge-PNG umfanekiso. Akukho ndlela ye-Nth-frame okanye ye-one-per-second. I-MPG ifana nenkqubo ye-MPEG ejikelezayo njenge-.mpeg — uluhlu lweeleta ezintathu luyi-DOS-era truncation, hayi ifomati eyahlukileyo.

Umfanekiso okhuphiweyo PNG uphuma njani kwisisombululo esipheleleyo?

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

Ndingayikhupha isakhelo ngasinye kwifayili MPG njenge PNG?

Ewe, ngee-Frames zonke kukhetho lokuHlanganisa i-Frame, kodwa khangela ubalo: imizuzu emine ye-30 fps yevidiyo inika imifanekiso eyi-1,800 PNG. Ukuba uhlala phantsi, khetha i-Frame eSingle kwaye ufake umzuzwana ofuna ukuwufaka endaweni.

Ingaba imifanekiso PNG iya kugcina umbala ophakamileyo MPG?

I-HDR footage ayimaphulwanga ithoni: i-frame nganye iguqulwa ukusuka kwi-MPG njengoko ikhowudiwe, ngoko i-frame ukusuka kwi-HDR MPG ingabonakali iphaphazela okanye icocwe ngaphandle njenge-PNG. Ividiyo eqhelekileyo (SDR) igcina imibala yayo.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka ku MPG ukuya ku PNG?

It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.

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

Enye ngaxeshanye. Isakhelo esipheleleyo sithatha ixesha elinye kwimizuzwana (umzekelo 83 ye 1: 23) kwaye sigcina esi sahlulo njenge PNG. Akukho ndawo yoluhlu lwexesha, ngoko ke qhuba uguqulelo kwakhona kwixesha elipheleleyo elingaphezulu.

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

Ewe. Iifayile ezilayishwe phezulu ze MPG ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga. Ukukhuphela kunye nokuguqulwa kwe PNG kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.

Kutheni i-PNG isakhelo sam esikhutshweyo simnyama?

I-motion blur ihlala ivela kumboneleli MPG (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?

Hayi. Umguquli awunakubakho ukukhangela kwemeko-bume kwaye akukho ndlela yesibini-nge-imizuzu: igcina isakhelo esifanayo kwisekondi ongenisayo okanye kwisakhelo ngasinye. Umfanekiso omnye kwimeko-bume, khupha isakhelo esifanayo kwixesha apho iimeko-bume zitshintsha khona.

Ndingasebenzisa i-PNG isakhelo esikhutshweyo ngokurhweba?

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