Media Encoder Standard definierar en uppsättning kodningsförinställningar som du kan använda när du skapar kodningsjobb. Du kan antingen använda en preset name för att ange i vilket format du vill koda mediefilen. Eller så kan du skapa egna JSON- eller XML-baserade förinställningar (med UTF-8- eller UTF-16-kodning. Sedan skickar du den anpassade förinställningen till kodaren. En lista över alla förinställda namn som stöds av kodaren Media Encoder Standard finns i Uppgiftsförinställningar för Media Encoder Standard.

Det här avsnittet visar förinställningen H264 Multiple Bitrate 4K Audio 5.1 i XML- och JSON-format.

Den här förinställningen ger en uppsättning med 12 GOP-justerade MP4-filer, från 2 000 kbit/s till 1 000 kbit/s och AAC 5,1-ljud. Detaljerad information om profil, bithastighet, samplingsfrekvens osv. för den här förinställningen finns i XML- eller JSON-koden som definieras nedan. Förklaringar av vad varje element innebär och giltiga värden för varje element finns i Media Encoder Standard schema.

Anteckning

Du bör få Premium reserverad enhetstyp med 4K-kodningar. Mer information finns i Skala kodning.

Anteckning

När du Width ändrar värdena och Height mellan lager kontrollerar du att proportionerna förblir konsekventa. Exempel: 1920x1080, 1280x720, 1080x576, 640x360. Du bör inte använda en blandning av proportioner, till exempel: 1280x720, 720x480, 640x360.
