MKV kuya PNG Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngizokhipha kanjani amafreyimu kusuka ku MKV ividiyo njenge PNG izithombe?

Layisha i-MKV bese uvula izinketho. Ukukhishwa kwefreyimu kunezindlela ezimbili: Ifreyimu eyodwa igcina i-PNG eyodwa kusuka ku-second ofaka (njengesibonelo 1, 5 noma 10.5), futhi Zonke ifreyimu zigcina ifreyimu ngayinye yevidiyo njengesithombe se-PNG. Akukho indlela ngayinye-Nth-frame noma eyodwa-kwesekunxele.

Isithombe esikhishwayo PNG siphuma kanjani ngesinqumo?

Isinqumo esifanayo njenge MKV ividiyo — 1080p umsuka ukhiqiza amafreyimu angama-1920×1080 PNG; 4K umsuka ukhiqiza amafreyimu angama-3840×2160 PNG. Buyisela ubukhulu ngemuva kokukhishwa uma ufuna amathumbnail amancane.

Ingabe ngizokhipha yonke ifreyimu kusuka kuhele MKV njenge PNG?

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

Ingabe izithombe PNG zizogcina umbala MKV olinganiselwe?

Ividiyo ye-HDR ayitholwe nge-tone-mapped: ifreyimu ngayinye iguqulwa kusuka ku-MKV njengoba i-coded, ngakho ifreyimu kusuka ku-HDR MKV ingabonakali i-flat noma i-washed out njenge-PNG. Ividiyo ejwayelekile (SDR) igcina imibala yayo.

Ithatha isikhathi esingakanani ukukhishwa kwefreyimu kusuka ku MKV kuya ku PNG?

Kuxhomekeka kubukhulu nesikhathi sohele. Amadokhumende amancane namasithombe avame ukulungiselelwa ngokushesha. Amavidiyo ade athatha isikhathi eside, ngoba amavidiyo aguqulwa aphinde akhode ifreyimu ngayinye.

Ingabe ngizokhipha amafreyimu eziqephuni ezikhethekile zesikhathi kwi-MKV video?

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

Ingabe i-MKV yami yevidiyo imfihlo ngesikhathi sokukhishwa kwefreyimu?

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

Kungani ama-PNG amafreyimu ami akhishwa amnyama?

Kuyinto evamile ukushaya isithombe kusuka kumthombo MKV (ikhamera ihamba lapho ifreyimu ithathwa khona). Zama ukukhetha ama-timestamps kusuka emibonweni ehlala njalo, noma ukhiphe amafreyimu ambalwa azungeze futhi ukhethe ocacile kakhulu. Ipayipi alikhiqizi ucacile.

Ingabe lesi sisetshenziswa sisekela ukukhishwa kwefremu eyodwa ngeshintsho lendawo?

Akuna. Umguquli awunakukhomba isiboniso futhi awunakho indlela yesikhathi esisodwa-ngesekunxele: igcina noma ifremu eyodwa ngesikhathi esilandelayo lapho ufaka khona noma ifremu ngayinye. Isithombe esisodwa sesithombe, khipha ifremu eyodwa ngesikhathi isiboniso sishintsha.

Ingabe ngisebenzisa amafreyimu akhishwayo PNG ngebhizinisi?

Yebo, ngaphansi kwelayisense elilawula i-MKV isihloko somthombo. Ushintsho lwefomethi alutholi icala — sifaka uphawu lwamanzi futhi sicela icala olungasebenzi kwi-PNG okuqukethwe.

MKV

I-MKV (Matroska) ingagcina amavidiyo angenamkhawulo, umsindo, kanye namathrekhi angezansi kufayela elilodwa, okulungele ama-movie.

PNG

Amafayela e-PNG asekela ukucaca futhi asebenzisa ukucindezela okungenakulahlekelwa, okwenza afaneleke kakhulu kuma-graphics, ama-logo, kanye nezithombe-skrini.
