WMV kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani ifreyimu kusuka ku WMV ividiyo njenge TIFF izithombe?

Layisha phezulu i WMV 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. WMV Windows Media Video, Microsoft ASF-based format kusuka Windows XP isikhathi. I-TIFF iyifomethi yefayela lesithombe ephawulwe kusukela ngo-1986, futhi iyifomethi yokuskena, ukushicilela kanye nokugcinwa kwefayela ezimbonini ezijwayelekile.

Kungani amafreyimu ami akhishwayo anemigqa ejikelezayo edlula kuwo?

Ngenxa yokuthi umsuka uxhunywe. WMV 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?

Uma nje i WMV ayizange itshetshezwe, ngoba WMV ayinaso isingeniso esikhethiwe sohluzo esikhethiwe sokuvala. Noma yini eWMV 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. WMV ngokuphumelelayo iphele efile: macOS, iOS, Android kanye nesipiliyoni ngasinye idinga isithathu-party decoders, futhi ezinye WMV amafayela zithwala DRM ukuthi akufanele kushintshwe ngaso sonke isikhathi.

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 WMV ividiyo — 1080p WMV ikhiqiza amafreyimu angama-1920×1080 TIFF; 4K WMV 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 WMV njenge TIFF?

Yebo, kodwa qaphela ngokubalwa kwefayela — i-30fps 1-minithi WMV 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 WMV olinganiselwe?

Yebo — umbala uqokwa nge-matrix esetshenziswa umsuka WMV (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 WMV kukhiqiza ~50 GB jikelele.

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

I WMV 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 WMV kuya ku TIFF?

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

Ingabe ngizokhipha amafreyimu ezikhathini ezikhethekile ku WMV?

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.

WMV

WMV yividiyo yeMicrosoft evela ku Windows Media era, encane ngesikhathi sayo kodwa ebuhlungu nganoma yini ngaphandle kweWindows.

TIFF

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