It took me a while but I worked it out....I save my frames as .iff...then AE>import>import multiple...then hit 1st one (.iff)...best guess or something...then I just drag and drop down to the render bar below...done.
Hope you find something good and that will work for you...I have only used AE a couple of times and know nothing about them mate...but its good enough for now...LOL
