WebM kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani ifreyimu kusuka ku WebM ividiyo njenge TIFF izithombe?

Layisha phezulu i WebM 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.

Ngabe usinqumo sinjani uma ifreyimu ngayinye ekhishwayo TIFF iphuma?

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

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

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

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

I WebM 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 WebM kuya ku TIFF?

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

Ingabe ngizokhipha amafreyimu ezikhathini ezikhethekile ku WebM?

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.

Ingabe i-WebM yami yevidiyo ifihlakele ngesikhathi sokukhipha ifreyimu?

Yebo — imodeli yobumfihlo efanayo nezo zonke iziguqulo. Ividiyo yomthombo kanye nefreyimu ekhishwayo TIFF iphathwa abasebenza ngokuzimela futhi isuswa ngaphakathi kwemizuzu; akukho ukuhlolwa komuntu, akukho ukuqeqeshwa kwe-corpus, akukho ukungena kweqembu lesithathu.

Kungani amafreyimu ami akhishwayo TIFF amnyama?

Kuyinto evamile kakhulu ukuthi ukunyakaza kokumnyama kubhakwe ku WebM - ikhamera noma okudingayo kwahamba lapho ifreyimu ithathwa. Khetha ama-timestamps kusuka emibonweni ehlala njalo, noma khipha amafreyimu azungeze futhi ukhethe okuqinile. Ipayipi alikwazi ukuhlela imininingwane engakhona.

Ingabe ngizokhipha i TIFF ngasinye soshintsho lwesiboniso ngaphandle kosuku lokuqapha?

Akukho emthonjeni oyinhloko — sebenzisa "1 ngomzuzwana" njengenketho efana nokulinganiselwa, bese ukhetha ifreyimu yokushintsha isithombe. Umqotho wokuthola isithombe ukhona kwindlela yokuhamba; sicela usizo uma kuzovula umthonjeni othile womsebenzi.

Ingabe ngisebenzisa amafreyimu akhishwayo TIFF ngokuhweba?

Yebo, ngaphansi kwelayisense elawula umsuka WebM. Ushintsho lwefomethi alukho ubufakazi — sifaka i-watermark futhi sichaza ukuthi akukho layisense ku TIFF. I-copyright ilandela umsuka, hhayi umguquli.

WebM

I-WebM yenzelwe iwebhu, inikeza ukusakaza ividiyo ngaphandle kwemali yokukhokha ngama-codec e-VP8/VP9.

TIFF

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