 In Broadcast there's 2 format in use Prores (Apple) and DNxHD (Avid).
 FFmpeg already support Alpha channel in Prores.mov files.
 How far are we to DNxHD support ?
 In my Understanding DNxHD never compress the Alpha Channel, is it a
 Stopper for the Encoder (or the decoder) ?

 Here is some test files, one is Prores with an alpha, the other is a DNxHD
