After 30 secods is trhe video


Also, using the replay, is there a way to pause the action? and still be able to use the camera controll. Like just pause the motion of the cars?

press shift U then use the "p" key to pause /unpause use shift F if you dont want the clutter

F2 and F3 slow or speed up the action too

SD.

Edit : just watched the vid (nice ) so you already know about F2/3 and shift U
