Hi Michael,
really appreciate your help, as I say I have very little experience in AE. I will describe my work flow and what I am trying to achieve.
I have created several video sequences in PPro and am trying to combine them in and AE comp.
Importing to AE basically dragging and dropping into AE project. starting with a white solid I add sequences and animate/resize/position etc as need be, at this time I have 1/solid, 1/text layer and 6/video sequences opening/overlapping and closing at intervals. Basically talking 10 minutes of sequences and condensing then into say 4 mins by resizing and overlapping.
The AE project seems to play smoothly although slow then I export by dragging and dropping back to the project panel in PPr it plays in source monitor but it refused to move to the time line.
hope this is understandable, regards jjb
