MOV kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani ifreyimu kusuka ku MOV ividiyo njenge TIFF izithombe?

Layisha phezulu i MOV futhi umguquli ubonisa isikhethi sefremu-sokuzisusa: yonke ifremu ye-Nth, amafremu ezikhathini ezikhethekile, noma ifremu eyodwa ngesekondi. Ifremu ngayinye ekhethiwe ikhodwe njengehele TIFF elilodwa futhi isethulo esigcwele siqoqwe kwi-ZIP archive yokulayisha. MOV Apple QuickTime isitsha, ethunyelwe ngo-1991 futhi namanje ifomu iPhone, iPad noma Final Cut Pro timeline ubhala ngokuzenzakalela. I-TIFF iyifomethi yefayela lesithombe ephawulwe kusukela ngo-1986, futhi iyifomethi yokuskena, ukushicilela kanye nokugcinwa kwefayela ezimbonini ezijwayelekile.

Ingabe izihloko ezingezansi zizovela kuma-TIFF amafreyimu engikhiphayo?

Akunakwenzeka uma beyi-subtitle track engokoqobo. MOV igcina izihloko ezingezansi njenge-stream yabo futhi umdlali uzobasusa phezu kwesithombe ngesikhathi sokudlala, ngakho ifremu eqoshiwe umguquli ubhala ngaphandle njenge-TIFF ine-pixels ehlanzekile ngaphansi. Izihloko ezingezansi eziboshwe kwividiyo ngaphambi kokuba ibe yi-MOV ziyinkinga ehlukile - lapho ziyingxenye yesithombe futhi ifremu ngayinye ekhishwayo igcina lezi.

Ingabe ngizokhipha i TIFF kusuka kusiqephu ngasinye se-MOV?

Akunakungathi inkinobho eyodwa, kodwa MOV yenza kube lula: amaphawu esigaba agcinwa ebhokisini njengezipho zosuku, ngakho funda uhlu lwesigaba ngaphandle kwefayela bese ufaka amahora ezindaweni zesiqephu. Uthola TIFF eyodwa ngesigaba ngasinye, ngokulandelelana, okuyindlela ejwayelekile yokwakha izithonjana zokurekhoda okude. Amacebo angenamagama esigaba ashiya ukukhetha izimo ngemehlo endaweni. MOV yifomethi abashicileli abaqeqeshiwe bacela, ngoba ihlala iphinda i-round-trips nge Final Cut Pro, Premiere ne DaVinci Resolve ngaphandle kokulahlekelwa kohlobo.

Ingabe i-TIFF ixhasa ukubukhali?

Ifomethi ikhona, kodwa umsuka awuna-alpha ukuwunika - amafreyimu wevidiyo namakhasi ashicilelwe agcwele ukucasuka, ngakho wonke ama-pixel afika aqinile. Isixhumanisi se-alpha sisebenza ngemuva: kusho ukuthi ungasakaza isiqephu se TIFF ngemuva ngaphandle kokushintsha ifomethi futhi. I-TIFF iphatha i-CMYK, 16-bit ububanzi, i-ICC efakwe ngaphakathi namaprofayili namadokhumende amakhasi amaningi, okuwukuthi okuthile okudingayo ukuphrinta nokugcinwa kwemisebenzi.

Ingabe amafayela TIFF azokhula kangako?

Okuningi kunalokho okubonayo, ngoba TIFF igcina wonke ama-pixel ngokugcwele kungafani nokulinganisela. I-1080p ihlala ifinyelela ku-2-5 MB futhi i-4K ihlala ifinyelela ku-6-15 MB, ngakho-ke ukukhishwa okude kusebenza ngokushesha. Lokhu kuyibhizinisi elilungile uma izithombe zidla ukukhiqizwa okuqhubekayo, futhi okubi uma zihamba ngqo kwikhasi le-web. I-TIFF iyindawo yokuqoqa engaphezu kwe-codec: ingagcina idatha engacindezelwanga, i-LZW, i-ZIP noma i-JPEG, kuze kube yi-32 bits ngasinye, ngekhasi eliningi kwifayela elilodwa.

Ngabe usinqumo sinjani uma ifreyimu ngayinye ekhishwayo TIFF iphuma?

Ukulungiswa okufanayo njenge MOV ividiyo — 1080p MOV ikhiqiza amafreyimu angama-1920×1080 TIFF; 4K MOV ikhiqiza amafreyimu angama-3840×2160 TIFF. Sebenzisa ukuguqula usayizi ngemuva kokukhipha uma ufuna amathumbnail amancane noma ama-social-media-size crops.

Ingabe ngizokhipha ifreyimu ngayinye esuka ku MOV njenge TIFF?

Yebo, kodwa qaphela ngokubalwa kwefayela — i-30fps 1-minithi MOV ikhiqiza amafreyimu angama-1,800 TIFF. Siwafaka ngokuzenzakalela ku-ZIP. Ku-clip ezide, "1 ngesekondi" (ifreyimu engu-60) noma ama-timestamps athile anikeza imiphumela elawulwayo.

Ingabe izithombe ezikhishwayo TIFF zizogcina umbala MOV olinganiselwe?

Yebo — umbala uqokwa nge-matrix esetshenziswa umsuka MOV (BT.709 ku-HD, BT.2020 ku-4K HDR). Umsuka we-HDR u-tone-map ku-SDR uma ukhishwa ku-TIFF ngoba amafomethi amaningi TIFF (PNG, JPG) angagcina ama-pixels we-HDR ahlukene ngokusemthethweni.

Yini ubukhulu behele lwesiphequluli esisodwa esikhishwayo TIFF?

Kuxhomekeka kusinqumo kanye ne TIFF codec. Ifreyimu ye-1080p PNG ivame ukuba 2 kuya ku-5 MB; i-1080p JPG esezingeni-85 ivame ukuba 200 kuya ku-500 KB; i-4K PNG ivame ukuba 6 kuya ku-15 MB. Kunzima kakhulu, ukukhishwa kwefreyimu ngayinye ye-PNG yemizuzu engu-10 1080p MOV kukhiqiza ~50 GB jikelele.

Ingabe i-TIFF ekhishwayo igcina i-EXIF camera metadata?

I MOV iqoqo aligcinanga i-EXIF nge-frame ngayinye ngendlela ikhamera ehlala isebenza ngayo, ngakho i TIFF amafayela aphuma nge-EXIF engenalutho. Sifaka `creation_time` indawo ekhombisa i-source frame timestamp ukuze uphinde uhlanganise i-bundle ngokulandelelana kokuthatha.

Ingabe ithatha isikhathi esingakanani ukukhishwa kwefremu kusuka ku MOV kuya ku TIFF?

Ukukhishwa kwefremu kushesha — 20 kuya ku-30% yomthombo wesikhathi sokuphila ku-standard pipeline. Iminithi engu-5 MOV → TIFF iqoqo liphelela ku-minithi eyodwa noma ngabe ifremu ibalwa, ngoba i-bottleneck yi TIFF encoder, hhayi MOV demuxer.

Ingabe ngizokhipha amafreyimu ezikhathini ezikhethekile ku MOV?

Yebo - ukhetho oluthuthukisiwe luthatha uhlu oluhlukaniswe nge-comma lwesikhathi (isibonelo `00:01:23,00:05:00,00:10:42`) futhi lukhiqiza ihele elinye TIFF ngesikhathi. Kuhle kuma-thumbnails wesigaba, ama-scene reference shots, noma ukuthumbnailing izifundo ezide.

MOV

I-MOV iyifomethi ye-QuickTime ye-Apple, esekela ividiyo nomsindo wekhwalithi ephezulu wokuhlela kobungcweti.

TIFF

Amafayela e-TIFF asekela ukujula kwe-bit ephezulu kanye nokucindezelwa okungenakulahlekelwa, okulungele ukuthwebula izithombe zobungcweti kanye nokuphrinta.
