Same problem. Black Magic Hyperdeck Studio generates MOV files using DNxHD codec. I need to edit the video using Premiere Pro CS5 / Windows Vista 64. The files play fine using QuickTime Player.
I downloaded from Avid and executed the file that’s supposed to install the codec. This seems to work fine.
When I try to import the files into Premiere, the error message is “Unsupported format or damaged file.”
I’ve also tried importing the files into After Effects. The error message is “File cannot be opened, it may be in an unsupported format.
I’ve combed through the Adobe and Avid forums. This seems to be a familiar problem. The suggestions either don’t work or are incomprehensible to me.
