Indlela yokuguqula MP4 ukuba TIFF

Inyathelo 1: Rhweba ngaphakathi MP4 iifayili usebenzisa iqhosha phezulu okanye nge shift nendawo.

Inyathelo 2: Nqakraza kwiqhosha 'Uguqulo' ukuqala uguqulo.

Inyathelo 3: Gcina ifayile yakho eguqulweyo TIFF iifayile

MP4 ukuba TIFF Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndizikhupha njani iifayili kwi-MP4 video njengeemifanekiso ze-TIFF?

Layisha phezulu ifayili ye-MP4 kwaye umguquli ubonisa umkhethi wesakhelo-sokukhupha: isakhelo ngasinye se-Nth, ii-frames kwi-timestamps ezichaziweyo, okanye i-frame enye ngesekondi. Isakhelo ngasinye esikhethiweyo sikhowudiwe njengefayili ehlukileyo ye-TIFF kwaye sidityaniswe njenge-ZIP yokukhuphela.

Umfanekiso okhuphiweyo we-TIFF uphuma njani kwisisombululo esipheleleyo?

Ubungakanani obufanayo njenge-MP4 video — umthombo we-1080p uvelisa i-1920×1080 TIFF iifayili; umthombo we-4K uvelisa i-3840×2160 TIFF iifayili. Yenza kwakhona ubungakanani emva kokukhupha ukuba ufuna iithumbnails ezincinci.

Ndingayikhupha isakhelo ngasinye kwifayili ye MP4 njenge TIFF?

Ewe, kodwa uqaphele ngobalo lwefayili - i-30fps 1-minute video ivelisa ii-frames ezili-1,800. Sizifaka kwi-ZIP archive ngokuzenzekelayo. Kwiiclip ezide sebenzisa ukhetho "1 ngesekondi" (i-frames ezili-60) okanye iziqinisekiso zexesha ezikhethekileyo.

Ingaba imifanekiso ye-TIFF iya kugcina umbala wokwahlulahlula i-MP4?

Ewe - umbala uguqulwa umbala nge-matrix efanayo esetyenziswa ngumbhali MP4 (BT.709 ye-HD, BT.2020 ye-4K HDR). Ababhali be-HDR babekwa kwi-tone-mapping ye-SDR xa bekhupha kwi-TIFF (i-PNG / JPG ayikwazi ukugcina amanqanaba e-pixels e-HDR ngokusemthethweni).

Lithini ubungakanani befayili yesakhelo esitsha se-TIFF?

Kuxhomekeke kwisisombululo kunye nokhetho lwe-codec. I-1080p PNG frame yi-2-5 MB; i-1080p JPG quality-85 frame yi-200-500 KB. Yandisa ngokubala i-frame ukuze ubungakanani be-ZIP — kwinqanaba eliphezulu, ukususwa kwe-frame nganye ye-10-min 1080p video kwi-PNG yi ~50 GB.

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

Isiqulathi seefayili MP4 asigcinanga i-EXIF yesakhelo ngasinye ngendlela ikhamera ehlala isebenza ngayo, ngoko ke iifayile ze TIFF ziphuma nge-EXIF engenanto. Sifaka `creation_time` indawo ebonisa i-timestamp yesakhelo somthombo ukuze uphinde ulungelelanise i-bundle.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka kwi-MP4 ukuya kwi-TIFF?

Ukutsala isakhelo kukhawuleza — ngokuqhelekileyo 20-30% yobude bomthombo kwindlela eqhelekileyo yokuhambisa. I-5-imizuzu MP4 → TIFF bundle igqiba malunga nemizuzu emi-1 ngaphandle kokuxhomekeka kubalo lwesakhelo, kuba i-bottleneck yi-TIFF encoder, hayi i-demuxer.

Ndingazikhuphela njani ii-frames kwixesha elikhankanyiweyo kwi-MP4 video?

Ewe - ukhetho oluphambili luyakwamkela uluhlu oluhlukaniswe nge-comma lweziqinisekiso zexesha (umzekelo `00:01:23,00:05:00,00:10:42`) kwaye luvelisa ifayili enye ye-TIFF ngesatifiketi sexesha. Isetyenziswa kwizifundo ezincinci okanye iziganeko ezibhekisa kuzo.

Ingaba i-MP4 video yam ifihlakele ngexesha lokususa isakhelo?

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngasinye. Ividiyo yombhalo kunye neefreyimu ezikhuphiweyo ziqhubekekiswa kubasebenzi ababekwe ngokuzimeleyo kwaye zicinywe kwimizuzu.

Kutheni i-TIFF isakhelo sam esikhutshweyo simnyama?

I-motion blur ihlala ivela kumgca ovela kumgca ovela kwi-MP4 (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?

Akukho kutyibiliko olusisiseko - sebenzisa ukhetho "1 ngomzuzwana" njengokwenkxaso, emva koko ukhethe ngokubonakalayo iifayili zotshintsho lwendawo. Umqokeleli wokufumana indawo okhethekileyo ukwi-roadmap.

Ndingasebenzisa i-TIFF isakhelo esikhutshweyo ngokurhweba?

Ewe, ngokuxhomekeke kwilayisensi elawula umthombo MP4 imixholo. Utshintsho lwefomati aluyi kuzisa naziphi na izilumkiso — asiyi kudibanisa naziphi na izilumkiso ze-watermark kwaye asiyi kuzisa naziphi na izilumkiso zelayisensi kwimveliso ye TIFF.
