WebM kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani ifreyimu kusuka ku WebM ividiyo njenge TIFF izithombe?

Layisha i-WebM bese uvula izinketho. Ukukhishwa kwefreyimu kunezindlela ezimbili: Ifreyimu eyodwa igcina i-TIFF eyodwa kusuka ku-second ofaka (njengesibonelo 1, 5 noma 10.5), futhi Zonke ifreyimu zigcina ifreyimu ngayinye yevidiyo njengesithombe se-TIFF. Akukho indlela ngayinye-Nth-frame noma eyodwa-kwesekunxele. I-WebM iyingxenye eqinile ye-Matroska eshicilelwe yi-Google ngo-2010 ekhethekile ekubeni i-HTML5 ividiyo ifakwe ibhokisi elikhululekile. I-TIFF iyifomethi yefayela lesithombe ephawulwe kusukela ngo-1986, futhi iyifomethi yokuskena, ukushicilela kanye nokugcinwa kwefayela ezimbonini ezijwayelekile.

Ingabe izihloko ezingezansi zizovela kuma-TIFF amafreyimu engikhiphayo?

Akunakwenzeka uma beyi-subtitle track engokoqobo. WebM igcina izihloko ezingezansi njenge-stream yabo futhi umdlali uzobasusa phezu kwesithombe ngesikhathi sokudlala, ngakho ifremu eqoshiwe umguquli ubhala ngaphandle njenge-TIFF ine-pixels ehlanzekile ngaphansi. Izihloko ezingezansi eziboshwe kwividiyo ngaphambi kokuba ibe yi-WebM ziyinkinga ehlukile - lapho ziyingxenye yesithombe futhi ifremu ngayinye ekhishwayo igcina lezi.

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 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, ngezo zonke iframes ku-Frame Extraction option, kodwa bheka ukubala: iminithi eyodwa ye-30 fps video inikeza izithombe ezingu-1,800 TIFF. Uma uhlala uhlala, khetha i-Frame eyodwa bese ufaka isithupha ofuna.

Ingabe izithombe ezikhishwayo TIFF zizogcina umbala WebM olinganiselwe?

Ividiyo ye-HDR ayimaphulwe ngethoni: ifreyimu ngayinye iguqulwa kusuka ku-WebM njengoba ikhodwe, ngakho ifreyimu kusuka ku-HDR WebM ingabonakali iphazili noma ihlanzwe njenge-TIFF. Ividiyo ejwayelekile (SDR) igcina imibala yayo.

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 ithatha isikhathi esingakanani ukukhishwa kwefremu kusuka ku WebM kuya ku TIFF?

It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.

Ingabe ngizokhipha amafreyimu ezikhathini ezikhethekile ku WebM?

Omunye ngasikhathi sinye. Ifremu eyodwa ithatha isikhathi esisodwa emaminithini (njengesibonelo 83 ku-1:23) futhi igcina ifremu njenge-TIFF. Akukho indawo yohlu lwezikhathi, ngakho sebenzisa ukuguqulwa kabusha kosuku ngalunye olungeziwe.

Ingabe i-WebM yami yevidiyo ifihlakele ngesikhathi sokukhipha ifreyimu?

Yebo. Amafayela WebM alayishwe phezulu aphathwa kumaseva ethu okuguqula, akukho muntu obhekana nawo, futhi angeke ahlukaniswe. Ukulayishwa kanye nokuguqulwa kwe TIFF kususwa ngokuzenzakalela cishe amahora angu-24 ngemuva kokuguqulwa, okushiya isikhathi sokulanda imiphumela. Bona /privacy/ ukufinyelela kunqubomgomo egcwele.

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.
