Thanks for the reply Steve. I DO want to IGNORE the alphs- it contains the sky. In 3D programs the sky is usually created in a dome fasion and the resulting files can either be knocked out for a different or better sky(skies take a while to render) or they the alpha can be ignored to keep the rendered sky in place. I have found the solution! In PPro you have to add the Video filter Alpha Adjust and click on Ignore Alpha in the effects control list. Wierd it does not work in the interpret fooyage command. A bug methinks!
Anyway- Alpha Adjust is the answer.
