I am using After Effects CS 5.5 on Windows 7. When I use the mouse to click / drag / scroll through the timeline, one view updates in real time, this is great! If I open a second view, it only updates that view when I finish scrolling.
I would like to be able to scroll back and forth through the timeline, and have two different compositions update in real time (live update)?
Is this possible?
The long answer is: No. It's not even a performance issue, it's how AE evaluates time, since time is fluid and can be mangled in a million ways from time-remapping to expressions...
It's basic functionality, as Mulenium says. AE cannot play back multiple streams at the same time even if both are already in RAM and disk cache. Synchronized scrubbing, especially with OpenGL acceleration, would be a great feature request.
Mylenium, Rick, thanks so much for the quick responses, very much appreciated!
