penting

Elastic Transcoder memeriksa pengaturan yang Anda tentukan untuk memastikan bahwa mereka memenuhi persyaratan Elastic Transcoder dan untuk menentukan apakah mereka mematuhi standar yang berlaku. Jika pengaturan Anda tidak valid untuk Elastic Transcoder, Elastic Transcoder mengembalikan respons HTTP 400 (ValidationException) dan tidak membuat preset. Jika pengaturan berlaku untuk Elastic Transcoder tetapi tidak benar-benar sesuai dengan standar, Elastic Transcoder membuat preset dan mengembalikan pesan peringatan dalam respon. Ini membantu Anda menentukan apakah pengaturan Anda sesuai dengan standar sambil memberi Anda fleksibilitas yang lebih besar sehubungan dengan file yang dihasilkan Elastic Transcoder.
