Indlela yokuguqula FLV kuya TIFF

Inyathelo 1: Ngenisa FLV amafayela usebenzisa inkinobho ngasentshonalanga noma ngoshicilela bese ushiya.

Inyathelo lesi-2: Chofoza inkinobho ethi 'Tshintsha' ukuqala ukuguqulwa.

Inyathelo 3: Qapha okuguqulwe TIFF amafayela

FLV kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngizokhipha kanjani amafreyimu kusuka ku FLV ividiyo njenge TIFF izithombe?

Layisha phezulu ihele FLV futhi umguquli ubonisa isikhethi sefreyimu-sokukhipha: nganoma iyiphi ifreyimu ye-Nth, amafreyimu ezikhathini ezicacisiwe, noma ifreyimu eyodwa ngesekondi. Ifreyimu ngayinye ekhethiwe ikhodwe njengehele TIFF elilodwa futhi lihlukaniswe njenge-ZIP yokulayisha phezulu.

Isithombe esikhishwayo TIFF siphuma kanjani ngesinqumo?

Isinqumo esifanayo njenge FLV ividiyo — 1080p umsuka ukhiqiza amafreyimu angama-1920×1080 TIFF; 4K umsuka ukhiqiza amafreyimu angama-3840×2160 TIFF. Buyisela ubukhulu ngemuva kokukhishwa uma ufuna amathumbnail amancane.

Ingabe ngizokhipha yonke ifreyimu kusuka kuhele FLV njenge TIFF?

Yebo, kodwa uqaphele ngokubalwa kwefayela - i-30fps 1-minute video ikhiqiza amafreyimu angama-1,800. Siwafaka ngaphakathi kwe-ZIP archive ngokuzenzakalela. Kweziqephu ezide sebenzisa "1 ngesekondi" (ifreyimu engu-60) noma ama-timestamps athile.

Ingabe izithombe TIFF zizogcina umbala FLV olinganiselwe?

Yebo — umbala uqoshwe nge-matrix efanayo esetshenziswa umsuka FLV (BT.709 for HD, BT.2020 for 4K HDR). Ama-HDR asuka ku-tone-mapped ku-SDR uma ekhishwa ku-TIFF (i-PNG / JPG ayikwazi ukugcina ama-pixels we-HDR ngokusemthethweni).

Yini ubukhulu behele lwesiphequluli esikhishwayo TIFF?

Kuxhomekeka kusinqumo kanye nokukhetha i-codec. Ifreyimu ye-1080p PNG yi-2-5 MB; ifreyimu ye-1080p JPG esezingeni eliphakeme-85 yi-200-500 KB. Yandisa ngokubalwa kwefreyimu ukuze usize i-ZIP — ku-extreme, ukukhipha ifreyimu ngayinye yevidiyo ye-10-min 1080p ku-PNG ku-~50 GB.

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

I FLV i Container ayigcinanga i-EXIF nge-frame ngendlela ikhamera ehlala isebenza ngayo, ngakho i TIFF ifaka amafayela ngaphandle nge-EXIF engenanto. Sifaka i-`creation_time` field ekhombisa i-source frame timestamp ukuze uphinde uhlanganise i-bundle.

Ithatha isikhathi esingakanani ukukhishwa kwefreyimu kusuka ku FLV kuya ku TIFF?

Ukukhishwa kwefreyimu kushesha — 20-30% yesikhathi somthombo ku-pipeline ejwayelekile. Iminithi engu-5 FLV → TIFF iqoqo liphele ngo-1 min ngaphandle kokubala kwefreyimu, ngoba i-bottleneck yi-TIFF encoder, hhayi i-demuxer.

Ingabe ngizokhipha amafreyimu eziqephuni ezikhethekile zesikhathi kwi-FLV video?

Yebo - isinqumo esiphakeme si accepts a comma-separated list of timestamps (e.g. `00:01:23,00:05:00,00:10:42`) and produces one TIFF file per timestamp. Useful for chapter thumbnails or scene reference shots.

Ingabe i-FLV yami yevidiyo imfihlo ngesikhathi sokukhishwa kwefreyimu?

Yebo — imodeli yobumfihlo efanayo nezo zonke iziguquli. Ividiyo yomsuka kanye nefreyimu ekhishwayo iphathwa ngabasebenza ngokuzimela futhi isuswa ngaphakathi kwemizuzu.

Kungani ama-TIFF amafreyimu ami akhishwa amnyama?

Kuyinto evamile ukushaya isithombe kusuka kumthombo FLV (ikhamera ihamba lapho ifreyimu ithathwa khona). Zama ukukhetha ama-timestamps kusuka emibonweni ehlala njalo, noma ukhiphe amafreyimu ambalwa azungeze futhi ukhethe ocacile kakhulu. Ipayipi alikhiqizi ucacile.

Ingabe lesi sisetshenziswa sisekela ukukhishwa kwefremu eyodwa ngeshintsho lendawo?

Ayikho ku- basic flow — sebenzisa i- "1 ngesekondi" option njenge-approximation, bese ukhetha ngokubonakalayo amafreyimu woshintsho lwesizinda. Isizinda esikhethekile sokuthola isizinda sikhona kwi roadmap.

Ingabe ngisebenzisa amafreyimu akhishwayo TIFF ngebhizinisi?

Yebo, ngaphansi kwelayisense elilawula i-FLV isihloko somthombo. Ushintsho lwefomethi alutholi icala — sifaka uphawu lwamanzi futhi sicela icala olungasebenzi kwi-TIFF okuqukethwe.

FLV

FLV yayiyibhokisi elingaphakathi kwevidiyo ye Flash kwi-web, manje idlulele kodwa ihlala isetshenziswa kakhulu ku-downloads ne-archives.

TIFF

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