I assume you have a series of rendered frames. Hopefully not in the .iff format, although Fcheck can reformat them into other file extensions. I usually use targa (.tga) files. Anyway, if you have your frames, it should just be a matter of double clicking the premier's Bin and selecting the first frame and checking the image sequance button. It should import them in a sequance. It's been a while since I used Premier, but I beileve that's how it works.
