Alphas out of alignment.

The alpha channels on MOVs i'm exporting from AE are all one pixel off once imported into Avid. You can see the pre-mult color one pixel above my objects. The bottom of my objects are also cut off by one pixel. How could i be importing something where the alpha channel is off?

Because you're not using the right kind of alpha channel? You're using premultiplied when you need straight, or vice-versa?

Tried both Straight & Pre-Mult. Same problem.

Just a thought: can this be related to some sort of quirky 3D camera? Perhaps this is a funky artifact of some motion blur done in post? These are both shots in the dark, but can hopefully get you going in the right direction...
