MOV ukuba PNG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu i-MOV 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. MOV yi Apple QuickTime isiqulathi seefayili, ethunyelwe ngo-1991 kwaye ihlala ifomati iPhone, iPad okanye Final Cut Pro umgca wexesha ubhala ngokumiselweyo. I-PNG yaphuhliswa ngowe-1996 njengento engekhoyo kwipateni ye-GIF, kwaye yayiyifomati yomfanekiso ongekhoyo kwi-web.

Ingaba izihloko ezingaphantsi ziya kubonakala kwi PNG iifayili endizikhuphayo?

Ayinjalo ukuba ziyindawo ebonakalayo yokulandela umbhalo osezantsi ephepheni. I MOV igcina umbhalo osezantsi ephepheni njengendlela yabo yokuhamba kwaye umdlali uzoba ngaphezulu komfanekiso ngexesha lokudlala, ngoko ke isakhelo esikhowudiweyo umguquli ubhala ngaphandle njenge PNG inee-pixels ezicocekileyo ezantsi. Iisihloko ezisezantsi eziboshwe kwividiyo phambi kokuba ibe yi MOV ziyingxaki eyahlukileyo - ngoko ziyinxalenye yomfanekiso kwaye yonke i-frame ekhutshwe igcina ezi.

Ingaba i-PNG ixhasa ukubonakaliswa ngokucacileyo?

Ifomati isebenza, kodwa umbhali akafuni i-alpha ukunika - ii-frames zevidiyo kunye neephepha ezibonisiweyo zicacile ngokupheleleyo, ngoko ke zonke ii-pixels zifika ziqinile. Isiqhagamshelanisi se-alpha sihlala sisetyenziswa emva koko: kuthetha ukuba ungacima into ephuma kwi-PNG kamva ngaphandle kokuguqula i-format kwakhona. I-PNG yinketho efanelekileyo yokuthatha imifanekiso yekhusi, ilogos, umzobo womgca nantoni na enemiphetho eqinileyo okanye ebonisa ngaphaya — akukho cingo, akukho mbala obandayo.

Ingaba iifayili PNG ziya kuba zikhulu kangakanani?

Ikhulu kunalo lonke ulindeleyo, kuba PNG igcina i-pixel nganye ngokuchanekileyo kunokuba ilinganise. I-1080p ihlala iwela ngaphantsi kwe-2-5 MB kwaye i-4K ihlala ngaphantsi kwe-6-15 MB, ngoko ke ukuphuma okude kudibanisa ngokukhawuleza. Oku kurhwebo oluchanekileyo xa imifanekiso i feed iqhubekeka, kwaye okubi xa zihamba ngqo kwiphepha le-web. I-PNG isebenzisa uxinzelelo lwe-DEFLATE ngaphezulu kwamagqabantshintshi okuskena acociweyo, ngoko ke i-pixel nganye ihlala ngokuchanekileyo, kunye ne-8-bit epheleleyo ye-alpha channel.

Uphi ubunzulu be-frame nganye ekhutshweyo PNG ephumayo?

Ubungakanani obufanayo ne-MOV ividiyo — i-1080p MOV ivelisa i-1920×1080 PNG ii-frames; i-4K MOV ivelisa i-3840×2160 PNG ii-frames. Sebenzisa uncedo lokuguqula ubungakanani emva kokukhupha ukuba ufuna ii-thumbnails ezincinci okanye ubungakanani be-social-media-crops.

Ndingayikhupha isakhelo ngasinye esitsha kwi MOV njenge PNG?

Ingaba imifanekiso ekhutshweyo PNG iya kugcina umbala ophakamileyo MOV?

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

Lithini ubungakanani befayili yesakhelo esitshatweyo PNG?

Ixhomekeke kwisisombululo kunye ne-PNG codec. I-1080p PNG frame ihlala i-2 ukuya kwi-5 MB; i-1080p JPG kwi-quality-85 i-200 ukuya kwi-500 KB; i-4K PNG i-6 ukuya kwi-15 MB. Kwimeko egqithisileyo, ukukhupha i-PNG frame nganye ye-10-minute 1080p MOV kwenza ~50 GB ngokupheleleyo.

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

Oku kuxhomekeke kubungakanani nobude befayile. Amaxwebhu amancinci kunye nemifanekiso ihlala ilungile ngokukhawuleza. Iividiyo ezide zithatha ixesha elide, kuba iinguqulelo ezininzi zevidiyo ziphinde zikhowudi iframe nganye.

Ndingazikhuphela iifayili kwixesha elikhankanyiweyo kwi MOV?

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.
