WEBM.to imapangidwa m'mphepete mwa chidebe chomwe chimatsegulidwa pa intaneti - VP9 kapena AV1 ndi Opus audio, chosinthidwa mwanjira iliyonse ndi tsamba lamakono lomwe silifunikira plug-in, lisensi kapena wosewera. Video ndi nkhani yomwe imayambitsa maulendo owonjezera omwe amawononga kwambiri - mafayilo ndi akulu ndipo aliyense wotsitsa amalipira maola ochepa. Kuyendetsa Kusintha JPEG pamodzi ndi ma conversions kumatanthauza kuti kutsitsa kokha kumakhudza ntchito yonse, osati kutsitsa kokha pa chida.
Kodi ndingachite chiyani ndi zotsatirazi pamene Kusintha JPEG yatha?
+
The Converter pa webusaitiyi amasinthana kanema pakati WebM, MP4, MKV, MOV ndi ena, kapena amatenga soundtrack kunja kwa zonse, popanda kulowa wina. Kutsatira njirayi kumakhudzana kwambiri ndi kanema kuposa komwe kuli: chilichonse chosinthanso ndi chiyambi china, choncho ochepa chabe omwe ali pakati pa chiyambi ndi fayilo yomwe mumafalitsa, ndizowoneka bwino.
Kodi Kusintha JPEG pano ndi chinthu chomwecho chomwe masamba a sibling amayendetsa?
+
Ma injini amagawana - mtundu wofanana wa ffmpeg ndi x264, x265 ndi libvpx, ogwira ntchito omwewo, ma limits omwewo. Zomwe WebM tsamba limawonjezera ndi kuwonekera pazinthu ndi codecs: zomwe zimasewera pamodzi, zomwe zimafunikira kubwezeretsa ndikuti zitha kusindikizidwa. Izi zimayambanso kuchokera ku facti imodzi ya mtundu womwe uwu ndi dzina la siteyi: WebM ndi VP9 kapena AV1 ndi Opus audio, zomwe masamba a decode mwachilengedwe koma zomwe ambiri a desktop olemba akhoza kusinthidwa pa kutumiza.
Kodi ndiyenera kukhala ndi akaunti, ndipo kodi zinthu zina zimasunga?
+
Sichingakhale akaunti, ndipo palibe chomwe chimaperekedwa: kanema wotsitsa umachotsa ntchito za ogwira ntchito pambuyo pomaliza ntchito, palibe chomwe chimawoneka ndipo palibe chomwe chimapezeka. Maakaunti aulere alipo pokhudzana ndi mbiri ndi kukula kwa batani, osati kulowa.
