Indlela yokuguqula WebM ukuba TIFF

Inyathelo 1: Layisha eyakho WebM iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

WebM ukuba TIFF Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-WebM ividiyo njenge-TIFF imifanekiso?

Layisha phezulu i-WebM uze uvule izinto ezikhethwayo. Ukutsala isakhelo kuneendlela ezimbini: i-Frame eSingle igcina i-TIFF enye ukusuka kwisekondi ongenisayo (umzekelo, 1, 5 okanye 10.5), kwaye Zonke ii-Frames zigcina zonke ii-frames zevidiyo njenge-TIFF umfanekiso. Akukho ndlela ye-Nth-frame okanye ye-one-per-second. I-WebM yinxalenye encinci eqinileyo ye-Matroska epapashwe yiGoogle ngo-2010 ekhethekileyo ukunika i-HTML5 ividiyo isiqulathi seefayili esingenazo iirhafu. I-TIFF yifomati yefayili yomfanekiso ophawulweyo ukusukela ngo-1986, kwaye yifomati yokukhangela, yoshicilelo kunye nokugcina iinjineli ezimiselwe.

Ingaba izihloko zesihloko ziya kubonakala kwi-TIFF iifayili endizikhupha?

Ayinjalo ukuba ziyindawo yomxholo ophambili. I WebM igcina umxholo ophambili njengothotho lwazo oluthile kwaye umdlali uzoba ngaphaya komfanekiso ngexesha lokudlala, ngoko isakhelo esikhowudiweyo umguquli ubhala ngaphandle njenge TIFF inee-pixels ezicocekileyo ezantsi. Isihloko esiphantsi esikhutshwe kwividiyo phambi kokuba ibe yi WebM siyingxaki eyahlukileyo - ngoko ziyinxalenye yomfanekiso kwaye yonke isakhelo esikhutshwe sizigcina.

Ingaba i-TIFF 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-TIFF kamva ngaphandle kokuguqula i-format kwakhona. I-TIFF iphatha i CMYK, ubunzulu be-16-bit, i-ICC efakwe ngaphakathi kunye namaxwebhu amaphepha amaninzi, eyona nto ishicilela kwaye ifuna uthungelwano lomsebenzi wokugcina.

Ingaba iifayili TIFF ziya kuba zikhulu kangakanani?

Ikhulu kunalo lonke ulindeleyo, kuba TIFF 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-TIFF yindawo yokugcina engaphezulu kwe-codec: inokuphatha i-data engacinezelwanga, i-LZW, i-ZIP okanye nakwi-JPEG, ukuya kuthi ga kwi-32 bits kwisiqhagamshelanisi ngasinye, ngeephepha ezininzi kwifayili enye.

Kunye nobunzulu obunjani isakhelo ngasinye esikhutshwe TIFF siphuma?

Ugqibo olufanayo njenge WebM ividiyo — i-1080p WebM ivelisa i-1920×1080 TIFF iifayili; i-4K WebM ivelisa i-3840×2160 TIFF iifayili. Sebenzisa uncedo lokuphinda ubungakanani emva kokukhupha ukuba ufuna iithumbnails ezincinci okanye ubungakanani bokusika i-social-media.

Ndingayikhupha isakhelo ngasinye esitsha kwi WebM njenge TIFF?

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

Ingaba imifanekiso ekhutshweyo TIFF iya kugcina umbala ophakamileyo WebM?

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

Yintoni ubungakanani befayili yesakhelo esitshatweyo TIFF?

Ixhomekeke kwisisombululo kunye ne TIFF 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 ebuhlungu, i-PNG frame nganye yokukhupha i-10-minute 1080p WebM ivelisa ~50 GB ngokupheleleyo.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka kwi WebM ukuya kwi TIFF?

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.

Ndingazikhupha iifayili kwixesha elikhankanyiweyo le WebM?

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

Ingaba i-WebM yevidiyo yam ifihlakeleyo ngexesha lokukhupha isakhelo?

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