Akukho indlela ngayinye-Nth-frame noma eyodwa-kwesekunxele.

Isithombe esikhishwayo PNG siphuma kanjani ngesinqumo?

Izinto ezibonakalayo ze-pixel ezifanayo njengesizinda MKV — i-1080p video ikhiqiza amafreyimu angama-1920x1080 PNG, isizinda se-4K sikhiqiza amafreyimu angama-3840x2160 PNG. Buyisela ubukhulu ngemuva kokukhipha uma ufuna amathumbnail amancane (sinayo i-/image-resize/ tool).

Ingabe izithombe PNG zizogcina umbala MKV we-HDR?

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?

Kungani ama-PNG amafreyimu ami akhishwa amnyama?

Kuyinto evamile ukushaya kwe-motion blur kusuka kumthombo MKV — ikhamera ihamba lapho ifreyimu ithathwa khona. Zama ukukhetha ama-timestamps kusuka emibonweni ehlala njalo, noma khipha amafreyimu ambalwa azungeze futhi ukhethe ocacile kakhulu. Ipayipi alikhiqizi ucacile.

Ingabe lesi sisetshenziswa sisekela ukukhishwa kwefremu-yesimo-soshintsho-lohlelo?

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 isizinda MKV isiqubulo. Ushintsho lwefomethi alutholi ubufakazi — sifaka i-watermark, sifaka ukulandelana, futhi siphakamisa ilayisense ku-PNG okuqukethwe.
