Isinyathelo 1: Layisha eyakho FLV amafayela usebenzisa inkinobho engenhla noma ngokuhudula bese uphonsa.

Isinyathelo 2: Chofoza inkinobho ethi 'Guqula' ukuze uqale ukuguqulwa.

Isinyathelo 3: Landa i-version yakho TIFF amafayela

FLV kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani ifreyimu ngayinye kusuka ku FLV 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 ikhishwa ku-FLV umsinga wevidiyo, ibhalwe njengehele TIFF elilodwa, futhi iqoqwe njenge-ZIP yokulayisha ngezansi.

Ngasiphi isixazululo izithombe ezikhishwayo TIFF ziphuma khona?

Isinqumo esifanayo njengesisuka ku FLV: 1080p FLV ikhiqiza amafreyimu angama-1920x1080 TIFF, 4K FLV ikhiqiza amafreyimu angama-3840x2160 TIFF. Umguquli awukhuphuli noma awukhuphuli isampula — ama-pixel alinganiselwa ngokuqondile kusuka ku-frame e-decoded. Sebenzisa /resize-image/ ngemuva kokukhishwa uma ufuna amathumbnails amancane.

Ingabe ngizokhipha ifreyimu ngayinye ye FLV njenge TIFF?

Yebo, kodwa qaphela inani lefayela - i-30 fps 1-minithi FLV ikhiqiza amafreyimu angama-1,800 TIFF. Siwafaka ngaphakathi kohele olulodwa lwe-ZIP ngokuzenzakalela. Kweziclips ezide, khetha "1 ngesekondi" esisetshenzisiwe (amafreyimu angama-60 ngomzuzu) noma khetha ama-timestamps athile. Ihora lama-FLV nganoma iyiphi ifreyimu lizokhiqiza izithombe ezingu-~100,000 TIFF.

Ingabe ama-TIFF amafreyimu azogcina umbala FLV wokuhlanganiswa?

Yebo — umbala uqokwa nge-matrix efanayo etholakalayo FLV umsuka we-stream ubonisa (BT.709 for HD, BT.2020 for 4K HDR). Ama-HDR asuka ku-tone-mapped ku-SDR uma ekhishwa ku-TIFF angagcina ama-HDR pixel ranges ngokusemthethweni (JPG, PNG-8). Cindezela i-high-bit PNG-16 noma i-TIFF uma ufuna ukugcina ubukhulu obubanzi be-dynamic range.

Ingabe incane ifreyimu ekhishwayo TIFF kwidiski?

Kuxhomekeka kusinqumo kanye nokukhetha kwe-TIFF codec: ifreyimu ye-1080p PNG iyisi-2-5 MB engalahleki, i-1080p JPG esezingeni le-85 iyisi-200-500 KB. Yandisa ngokubalwa kwefreyimu ukuze usize i-ZIP — ekugcineni, ukukhipha i-PNG ngayinye yefreyimu yemizuzu engu-10 1080p FLV kulinganiselwa ku-50 GB futhi kuhlukaniswe ngezi-ZIPs eziningi.

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

I FLV i Container ayihambisani ne-EXIF ye-frame ngayinye ngendlela ikhamera ehlala khona eyenza ngayo, ngakho i TIFF amafayela aphuma nge-EXIF blocks engenanto. Umguquli ufaka `creation_time` indawo ekhombisa i-source frame timestamp, ngakho ungaphinde uhlela i-bundle ngendlela ye-chronological noma ulinganise nesihloko esingezansi / izihloko zezinkomba.

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

Ukususa ifreyimu kushesha - 20-30% yesikhathi somthombo. Iminithi engu-5 i FLV -> TIFF iphele ngeminithi engu-1 kungakhathaliseki ukuthi ifreyimu eminingi ukhetha, ngoba ibhodlela liyi TIFF encoder libhala amafayela amancane ambalwa ngokufanayo, hhayi i FLV demuxer.

Ingabe ngizokhipha amafreyimu ngesikhathi esifanele ngaphakathi kwe-FLV video?

Yebo - isinqumo sesikhathi esiphakeme sivuma uhlu oluhlukaniswe nge-comma (isibonelo `00:01:23, 00:05:00, 00:10:42.5`) futhi sikhiqiza ihele elinye TIFF ngesikhathi. Kusetshenziswa kumathumbnail esiga-nyezi, ama-shots endawo yokubhekisa, noma ukuthuthukisa ikhasi lokuxhumana lokubuyekeza.

Ingabe FLV yami imfihlo ngesikhathi sokukhishwa kwefreyimu?

Yebo — imodeli yobumfihlo efanayo njengezo zonke iziguquli. Umsuka FLV kanye ne-TIFF ekhishwayo iqhutshwa kubasebenzi abahlukanisiwe futhi isuswa ngaphakathi kwemizuzu yokuqedwa.

Kungani ama-TIFF amafreyimu ami akhishwa amnyama?

Kuyinto evamile kakhulu ukuthi ukungqubuzana kokuhamba kwe-motion kufakwe emthonjeni FLV (ikhamera noma okuxoxwa ngawo kwahamba ngesikhathi ifreyimu ithathwa). Zama ukukhetha ama-timestamps kusuka emibonweni ehlala njalo, noma ukhiphe amafreyimu ambalwa azungeze futhi ukhethe ocacile kakhulu. Ipayipi alihlanganiseli imininingwane engasekho ku-FLV.

Ingabe umguquli ungakhetha ifreyimu eyodwa ngeshintsho lendawo yokubukela ku FLV?

Akukho emthonjeni oyinhloko - sebenzisa i-"1 ngesekondi" emiselwe ngaphambi koku njengesimo esincane futhi ubheke ngokucacile i-bundle yezinkinga zesizinda. Isizinda esikhethekile sokuthola isizinda (sisebenza nge-ffmpeg select=gt(isizinda)) sikwi-roadmap futhi sizowela ku-TIFF ukukhishwa kamuva kule nyanga.

Ingabe ngisebenzisa amafreyimu akhishwayo TIFF ngebhizinisi?

Yebo, ngaphansi kwelayisense elawula i-FLV isihloko somthombo. Ukuguquka kuyisimo soshintsho - icopyright ku-FLV isihloko sihlala kulowo ogcina isihloko. Sifaka i-watermark, akukho uphawu lokungenisa, futhi sicela i-TIFF i-bundle.

FLV

I-FLV (I-Flash Video) ifomethi yesiqukathi sevidiyo eyakhiwe yi-Adobe. Ivamise ukusetshenziselwa ukusakazwa kwamavidiyo aku-inthanethi futhi isekelwa i-Adobe Flash Player.

TIFF

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