Random thoughts…
If you export an AAF file with media from Avid MC, you can open that in Premiere Pro CC and it will play just fine.
Not sure if that is helpful to you.
Another thing…if you have Avid MC 8 and not an old version, you can capture in Apple Pro Res MXF on a Mac instead of using the old Avid 1:1 Meridien codec. This will speed up exports to Apple Pro Res QuickTime, as it’s simply a rewrap and not a transcode.
You did not say whether you have an Avid DX Nitris/Mojo. If you have a third party card (AJA, Blackmagic), you could use Premiere to capture Apple ProRes QuickTime directly. You could also just use the deck control software for your card (AJA Control Room or Blackmagic Media Express).
