I'm not getting audio from a ProRes Quicktime importing to Premiere or Media Encorder. Files do have audio when played with windows quicktime player or Sorenson Squeeze.
Premiere shows it has audio, just a flat line.
Premiere Pro 5.5
Windows 7
Quicktime player 7
ProRes file:
1920x1080 Squrare Pixel
