I'm having AAE problems. It was working fine then started doing this all of a sudden. My clip is 59.94fps the comp setttings frame rate is set at 59.94. When I preview it plays in slow mo. If I then go and change the comp settings to 29.97 the the preview looks correct. Have you ever heard of this or know how to fix it? I have restared and issue did not fix it self.
Check your ram render settings (the panel that shows right on the default template) and see what framerate its set to. Also you might be limited if you use spacebar instead of the 0 key on the numpad to render.
