MPG kuya PNG Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngizokhipha kanjani amafreyimu kusuka ku MPG ividiyo njenge PNG izithombe?

Layisha i-MPG 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. MPG iyi-MPEG i-program stream efanayo ne-.mpeg — isibonisi sokubhala esithathu siyi-DOS-era truncation, hhayi i-format ehlukile.

Isithombe esikhishwayo PNG siphuma kanjani ngesinqumo?

Isinqumo esifanayo njenge-MPG ividiyo — 1080p ikhiqiza amafreyimu angu-1920×1080 PNG; 4K ikhiqiza amafreyimu angu-3840×2160 PNG. Sebenzisa /resize-image/ ngemuva kokukhishwa uma ufuna amathumbnails amancane noma ama-social-media-sized assets.

Ingabe ngizokhipha yonke ifreyimu kusuka kuhele MPG 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 MPG olinganiselwe?

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

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

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 eziqephuni ezikhethekile zesikhathi kwi-MPG 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-MPG yami yevidiyo imfihlo ngesikhathi sokukhishwa kwefreyimu?

Yebo. Amafayela MPG 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 emthonjeni (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 uhlaka — ngakho, sebenzisa /upscale/ ku-PNG okhishwayo ngemuva.

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-MPG isihloko somthombo. Ushintsho lwefomethi alukho ubufakazi — sifaka i-watermark, sifaka ukulandelela, futhi sicela alikho ilayisense ngaphezulu kwe-PNG okuqukethwe. Ividiyo yendawo yomphakathi ikhiqiza amafreyimu wendawo yomphakathi; isithombe sakho sihlala sakho.

MPG

I-MPG iyisandiso sefayela samafayela evidiyo e-MPEG-1 noma e-MPEG-2. Ngokuvamile isetshenziselwa ukudlalwa kwevidiyo nokusabalalisa.

PNG

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