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.

Inyathelo lesi-3: Khuphela i-converted yakho TIFF iifayile

WebM ukuba TIFF Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

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

Uphi ubunzulu be-frame nganye ekhutshweyo TIFF ephumayo?

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

Ndingayikhupha isakhelo ngasinye esitsha kwi WebM njenge TIFF?

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

Ingaba imifanekiso ekhutshweyo TIFF iya kugcina umbala ophakamileyo WebM?

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

Lithini 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 egqithisileyo, ukukhupha i-PNG frame nganye ye-10-minute 1080p WebM kwenza ~50 GB ngokupheleleyo.

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

Isiqulathi seefayili WebM asigcinanga i-EXIF yesakhelo ngasinye ngendlela ikhamera ehlala isebenza ngayo, ngoko ke ii-TIFF 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 WebM ukuya ku TIFF?

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

Ndingazikhuphela iifayili kwixesha elikhankanyiweyo kwi WebM?

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

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

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngalinye. Ividiyo yombhalo kunye nee-TIFF ze-frames ezikhuphiweyo ziqhubekekiswa kubasebenzi abakhuselekileyo kwaye zicinywe kwimizuzu; akukho hlaziyo lomuntu, akukho qeqesho lwe-corpus, akukho kufikelela kweqela lesithathu.

Kutheni i-TIFF isakhelo sam esikhutshweyo simnyama?

I-motion blur ihlala i-baked kwi-WebM source - ikhamera okanye into ehambayo xa isakhelo sathathwa. Khetha i-timestamps ukusuka kwimiboniso ehlala ikhona, okanye uthathe i-frames ezibekwe phantsi uze ukhethe ezicacileyo kakhulu. I-pipeline ayiqwalaseli inkcukacha ezingakhoyo.

Ndingayikhupha i TIFF enye ngento etshintshayo yendawo ebonakalayo endaweni yexesha elimiselweyo?

Akukho kutyibiliko olusisiseko - sebenzisa ukhetho "1 ngomzuzwana" njengokwencam, emva koko ukhethe ngokubonakalayo iifayili zotshintsho lwendawo. Umgcini-ndawo wokukhangela utyibiliko ubekwe kwi-roadmap; thumela i-ping kuthi ukuba iyakucima umngcipheko wokuhamba komsebenzi.

Ndingasebenzisa i-TIFF isakhelo esikhutshweyo ngokurhweba?

Ewe, ngokuxhomekeke kwilayisensi elawula umthombo WebM umxholo. Utshintsho lwefomati aluyi kudibanisa naziphi na izilumkiso - siza kudibanisa naziphi na iziphawuli zamanzi kwaye siqinisekise naziphi na ilayisensi ngaphezulu kwe TIFF imveliso. Ilungelo lokushicilela lilandelela umthombo, hayi umguquli.
