DivX kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani ifreyimu ngayinye kusuka ku DivX njenge TIFF izithombe?

Layisha phezulu ihele DivX futhi umguquli ubonisa isikhethi sefreyimu-sokukhipha: nganoma iyiphi ifreyimu ye-Nth, amafreyimu ezikhathini ezicacisiwe, noma ifreyimu eyodwa ngesekondi. Ifreyimu ngayinye ekhethiwe ikhishwa ku-DivX umsinga wevidiyo, ibhalwe njengehele TIFF elilodwa, futhi iqoqwe njenge-ZIP yokulayisha ngezansi. I-DivX ibiza i-codec hhayi ibhokisi — i-MPEG-4 Part 2 isebenzisa i-DVD eyisikhashana ku-CD eyodwa ekhona ngo-1999. I-TIFF iyifomethi yefayela lesithombe ephawulwe kusukela ngo-1986, futhi iyifomethi yokuskena, ukushicilela kanye nokugcinwa kwezinto eziphilayo ezijwayelekile.

Kungani amafreyimu ami akhishwayo anemigqa ejikelezayo edlula kuwo?

Ngenxa yokuthi umsuka uxhunywe. DivX okuqukethwe kusuka ku-broadcast ne-DVD era igcina ama-fields amabili aphakathi nendawo aphezulu ngefremu ngayinye, athathwe ngengxenye engu-50 yesithupha, futhi i-still ekhishwa ngokuqondile ibonisa ukuthi zombili zixhunywe ndawonye njenge-combing nganoma yini ehambayo. Vumela u-deinterlacing ngaphambi kokukhipha futhi i-still ngayinye ikhiwa kusuka ku-frame eqhubekayo evuselelwe.

Ingabe ngithola ama-TIFF amafreyimu ngaphandle kwesihloko esingezansi?

Uma nje i DivX ayizange itshetshezwe, ngoba DivX ayinaso isingeniso esikhethiwe sohluzo esikhethiwe sokuvala. Noma yini eDivX ebonisa esigabeni isithombe, ngakho i TIFF ngayinye ikhiqiza ukukhishwa futhi akukho sinqumo esisusayo ngemuva. lapho ihele elihlukile lesihloko likhona eduze kwevidiyo, khipha kusuka emthonjeni ogcina ama-2 ahlukene futhi ama-frames aphuma ahlanzekile. I-DivX idinga i-bitrate ephindwe kabili kune-H.264 ukuze ikwazi ukukhiqiza ngekhwalithi efanayo futhi ayinakho indlela ye-HDR, 10-bit umbala noma izixazululo ezingaphezu kwe-1080p.

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 ifaka amaprofayili namadokhumende amakhasi amaningi, okuwukuthi okuthile okudingekayo 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.

Ingabe ihele elikhulu kakhulu DivX lizokhuphula ngokuphumelelayo?

Ama-akhawunti amahhala afinyelela ku-100 MB ngefayela ngalinye, futhi DivX ama-akhowudi asebenza kabanzi ngoba ifomu lifaka i-chunk ngayinye engaphezulu kwedatha yevidiyo. I-Premium iphakamisa i-cap ngokuqinile. Uma ihele lihlukaniswe ngama-parts amanani ngenxa ye-format ceiling, thumela ngazo zonke futhi zithathwe njengemisebenzi eyodwa.

Ngasiphi isixazululo izithombe ezikhishwayo TIFF ziphuma khona?

Isinqumo esifanayo njengesisuka ku DivX: 1080p DivX ikhiqiza amafreyimu angama-1920x1080 TIFF, 4K DivX 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 DivX njenge TIFF?

Yebo, kodwa qaphela inani lefayela - i-30 fps 1-minithi DivX 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-DivX nganoma iyiphi ifreyimu lizokhiqiza izithombe ezingu-~100,000 TIFF.

Ingabe ama-TIFF amafreyimu azogcina umbala DivX wokuhlanganiswa?

Yebo — umbala uqokwa nge-matrix efanayo etholakalayo DivX 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 DivX kulinganiselwa ku-50 GB futhi kuhlukaniswe ngezi-ZIPs eziningi.

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

I DivX 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 DivX kuya ku TIFF?

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

DivX

I-DivX ubuchwepheshe bokucindezela ividiyo obuvumela ukucindezelwa kwevidiyo kwekhwalithi ephezulu enosayizi bamafayela amancane uma kuqhathaniswa. Ivame ukusetshenziselwa ukusatshalaliswa kwamavidiyo aku-inthanethi.

TIFF

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