I have added an after effects project to my timeline, and that takes a lot of cpu resource to render.
What I want to do is to prerender only the nested subsequence containing that AE composition to aid the renderer in premiere, but that seems to be ignored, it still plays awfully slow.
I do not want a solution where I save the background to a video file manually because that will obviously affect the quality of the final video rendering.
This is the particle background that I created in AE with the aid of the tutorial on.
So I created a nested sequence of it and prerendered that one (selecting the clip and in the menu use sequence->render selection.
After half an hour, the three minute long clip has been rendered as you see above and the red bar at the top has turned green.
It also plays nicely.
The parent clip as you see shows that bar in red.
When I try to play the video in premiere, it seems like it does not make use of that prerendition of the nested sequence because it is awfully slow playback.
What did I do wrong?
