MOV ukuba PNG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu i MOV kwaye umguquli ubonisa umkhethi wesakhelo-sokukhupha: isakhelo ngasinye se-Nth, iisakhelo kwixesha elikhankanyiweyo, okanye isakhelo ngasinye kwisiqingatha seyure. Isakhelo ngasinye esikhethiweyo sikhowudiwe njengefayili ye-PNG kwaye iseti epheleleyo ifakwe kwi-ZIP yovimba wokukhuphela. 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.

Ndingayitsala enye PNG ngaphandle kwesihloko ngasinye se MOV?

Ayiba iqhosha elinye, kodwa i MOV iyenza ibonakale icacile: iimpawu zesiqendu zigcinwa kwisiqulathi seefayili njengeziphawuli zexesha ezibizwa ngokuba ziphawuli zexesha, ngoko funda uluhlu lwesiqendu ngaphandle kwefayile kwaye ucofe ezixesha kwindawo yesiqendu sexesha. Ufumana enye PNG kwisiqendu ngasinye, ngokulandelana, eyiyo indlela eqhelekileyo yokwakha imifanekiso eqingqiweyo yoshicilelo olude. Amacebo angenamanqaku esiqendu ashiya ukukhetha imiboniso ngemehlo endaweni. MOV yifomati ababhali abaqeqeshiweyo becela, kuba ihlala iphinda ijikeleze-ihambo nge Final Cut Pro, Premiere ne DaVinci Resolve ngaphandle kokungasebenzi kohlobo.

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?

Ewe, kodwa uqaphele ngobalo lweefayili - i-30fps 1-minute MOV ivelisa i-1,800 PNG iifayili. Sizipakisha kwi-ZIP ngokuzenzekelayo. Kwiiclip ezide, ukhetho "1 ngomzuzwana" (iifayili ezi-60) okanye iziqinisekiso zexesha elikhankanyiweyo zinika isiphumo esiphathwayo.

Ingaba imifanekiso ekhutshweyo PNG iya kugcina umbala ophakamileyo MOV?

Ewe — umbala uguqulwa kwikhowudi nge-matrix esetyenziswa ngumboneleli MOV (BT.709 ye-HD, BT.2020 ye-4K HDR). Umboneleli we-HDR udweliswe nge-tone-mapping kwi-SDR xa uphuma kwi-PNG kuba i-PNG ifomati (PNG, JPG) ayikwazi ukugcina i-HDR pixel ranges ngokusemthethweni.

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.

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

Isiqulathi seefayili MOV asigcinanga i-EXIF yesakhelo ngasinye ngendlela ikhamera ehlala isebenza ngayo, ngoko ke ii-PNG iifayili ziphuma nge-EXIF engenanto. Sifaka `creation_time` indawo ebonisa umhla wokugqitywa kwesakhelo somthombo ukuze uphinde ulungelelanise i-bundle ngokulandelana kokuthatha.

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

Ukukhupha isakhelo kukhawuleza - ngokuqhelekileyo 20 ukuya kwi 30% yobude bomthombo kwindlela eqhelekileyo yokuhambisa. Imini emihlanu MOV → PNG iqela ligqiba malunga nemizuzu ngaphandle kokucinga ngobalo lwesakhelo, kuba ibhotile yengxowa yi PNG encoder, hayi i MOV demuxer.

Ndingazikhuphela iifayili kwixesha elikhankanyiweyo kwi MOV?

Ewe - ukhetho oluphambili luyakwamkela uluhlu oluhlukaniswe nge-comma lweziqinisekiso zexesha (umzekelo `00:01:23,00:05:00,00:10:42`) kwaye luvelisa ifayile enye PNG ngesatifiketi sexesha ngasinye. Isetyenziswa kwizifundo ezincinci zesahluko, iziganeko ezibhekisa kwimifanekiso, okanye izifundo ezide ezibonisa imifanekiso emifutshane.

MOV

I-MOV yifomathi ye-QuickTime ka-Apple, exhasa ividiyo kunye nesandi esikumgangatho ophezulu sokuhlela ngobuchwephesha.

PNG

Iifayili ze-PNG zihambelana nobunzulu obubonakalayo kwaye zisebenzisa ukucinezela okungalahleki, zenza ukuba zilungele amagrafiki, ilogos, kunye nemifanekiso yekhusi.
