I cannot find the solution to this and I can't understand how no one else is having this problem (at least I haven't seen any other posts on this).

I render most all of my alphas out as DNxHDs. The alpha channel is showing as black in Premiere instead of transparent.  I have played with the Modyfy>Interpret Footage to no avail. I have tried it on 4 different computers.

My alpha clips worked perfectly fine in CS5, but in CS6 the exact same project can't handle the alphas.

I need some help with this. I'm stuck even worse now since I can't go back to CS5 with my project since I've already worked in CS6. (Or is there a way to downgrade my project back to CS5?)

Any help would be greately appreciated. I'm supposed to render this out for a client today.

This is a known bug that we were unfortunately not able to address before shipping. For now if you would like a temporary workaround please open up:

 

C:\Users\{USER}\AppData\Roaming\Adobe\Common\MediaCoreQTCodecRulesCS6. xml
/Users/{USER}/Library/Application Support/Adobe/Common/MediaCoreQTCodecRulesCS6.xml 

 

Then find the four lines containing ’AVdn’ that say decode. Change the decodefourcc at the end of the line from ’2vuy’ to ’argb’.

Well, I just got to trying this out and unfortunately it doesn't do anything. It's doign the same thing. 

Here's the before and after pics of my XML file. I assuem I did it right. 

The other two pics are of the exact same AE render with the alpha.  The first one is using the QT/animation codec, the second is with the QT/DNxHD codec.  Both work on CS5, but only the animation codec works in CS6.

Any other suggestions?

Any news on this? I can't belive I'm the only one out there with this problem. I have installed CS6 on 3 computers to test out this problem and it happens on all 3.

When I apply the "fix" above, the problem goes away until after a computer restart.
