M4V kuya PNG Ukushintsha

Ngiyisusa kanjani ifreyimu kusuka ku M4V ividiyo njenge PNG izithombe?

Layisha i-M4V bese uvula izinketho. Ukukhishwa kwefremu kunezindlela ezimbili: Ifremu eyodwa igcina i-PNG eyodwa kusuka ku-second ofaka (njengesibonelo 1, 5 noma 10.5), futhi Zonke ifremu zigcina ifremu ngayinye yevidiyo njengesithombe se-PNG. Akukho indlela ngayinye-Nth-frame noma eyodwa-kwesekunxele.

Ngabe isithombe esikhishwayo PNG siphuma ngesinqumo esingakanani?

Ukulungiswa okufanayo njenge M4V ividiyo — umsuka we-1080p ukhiqiza amafreyimu we-1920×1080 PNG; umsuka we-4K ukhiqiza amafreyimu we-3840×2160 PNG. Buyisela ubukhulu ngemuva kokukhishwa uma ufuna amathumbnail amancane.

Ingabe ngizokhipha yonke ifreyimu kusuka kuhele M4V 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 M4V olinganiselwe?

Ividiyo ye-HDR ayitholwe nge-tone-mapped: ifreyimu ngayinye iguqulwa kusuka ku-M4V njengoba i-coded, ngakho ifreyimu kusuka ku-HDR M4V ingabonakali i-flat noma i-washed out njenge-PNG. Ividiyo ejwayelekile (SDR) igcina imibala yayo.

Ingabe ithatha isikhathi esingakanani ukukhishwa kwefremu kusuka ku M4V 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 ezikhathini ezikhethekile kwi M4V ividiyo?

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-M4V yami yevidiyo ifihlakele ngesikhathi sokukhipha ifreyimu?

Yebo. Amafayela M4V 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/ ukuphoqa okuphelele.

Kungani amafreyimu ami akhishwayo PNG amnyama?

Kuyinto evamile ukushaya umsindo ovela emthonjeni M4V (ikhamera ihamba lapho ifreyimu ithathwa). Zama ukukhetha ama-timestamps kusuka emibonweni ehlala njalo, noma khipha amafreyimu ambalwa azungeze futhi ukhethe ocacile. Ipayipi alikhiqizi ucacile.

Ingabe le thuluzi lixhasa ukukhishwa kwefremu eyodwa ngeshintsho lendawo yokubukela?

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 ngokuhweba?

Yebo, ngaphansi kwelayisense elawula umsuka M4V. Ushintsho lwefomethi alukho ubufakazi — sifaka akukho phawu lwamanzi futhi sicela akukho bufakazi belayisense ku PNG.

M4V

M4V yi Apple uhlobo MP4 ukuthi kungase kube FairPlay DRM, okuyinto okuthi ivimbela abanye abadlali kusukela ukuvula.

PNG

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