I have a few QT and AVI clips with alpha channels but I am not sure whether they need to be converted to something else prior to importing into a PI project. How about importing them into the emitter library for added permanence?
Thanks for the quick reply. I'd like to use the QT files as particles. In PI I created a background and in the layers panel on the left I right clicked on import but all I got was a position date dropdown and then a choose import from AE 5-8. I am currently using CS5 AE but didn't think I would need to go there. I just wanted to use Jose Burgos' Marlin download as a particle.
How to import and how to bring them even into the one project library I guess is what I need to know. I haven't used PI in some time but now I have a big project where I will be using it quite a bit using many of the particles in PI as well as rotoscoped frames from AE.
