I posted this on PP group without success. I am thinking maybe it is an AE problem. I have attached the Project file and a couple pics to demonstrate the banding. I have been going at this for a few days trying every variation that I can think of without success. Any input would be greatly appreciated.

First problem I encounter is the export from AE. I select AVI - Matrox Uncompressed + Alpha but the Alpha option is greyed out (jpg attached). Anyone else experiencing this?
Instead I export as Matrox Mpg-2 I-Frame + Alpha without problems.
In PP I have source media on track 1 and AE lower third scrolling text on Track 2 (above track 1). Everything looks prestine on PP program monitor and on external production monitor. Export timeline and severe banding occurs.
I have attempted exporting AE file in a number of different file types without any difference. I have also attempted exporting PP sequence in a number of different files types without success.
Just rendered it out as Microsoft AVI, codec set to NONE. Banding still there.
I can see where the render might add some subtle compression banding but what I am experiencing is well beyond that as you can see from the JPG's that I have attached.
It is a 90min program with many instances of this effect. Bringing everything into AE just to get a clean render and then back into PP is going to kill me for time. Then once the alterations come in it is going to get rediculous.
Is this what the norm is for AE alpha? Or am I dealing with a unique problem?
