The basic problem i'm having is that when i export from flash, I export as a png sequence with the amount of frames needed in after effects. Though when I import it into after effects the PNG sequence lasts only about half the amount of frames that it actually has! Both documents have the same FPS.
File --> Interpret Footage --> Main
THANK YOU!!!! It was at 30 FPS, I was spending hours importing a new PNG sequence 1 frame extra at a time trying to fix it!
Totally fixed the issue.
