Thanks Chris. That’s a good point so i checked it. the images are 640×480 pixels and the resolution is 72. when i load and edit the jpegs (without using PS or AE) in Avid and do a comparable move with Avid’s ‘picture-in-picture’ with HQ button clicked they look fine. when i don’t use the Avid HQ button on the jpegs i get similar aliasing effect as the AE rendered QT.
