Actually i'm using AE at school, so i dont have any manual. And i guess its not a copy version (they dont use ripped stuff here, i guess).
I never used AE before, only Premiere. I also made a search in the program, always by something like "speed" or "duration" like in Premiere, but without finding anything. I couldnt find that also in the AE help.

The software is a bit different from Premiere, so im still struggling. Sorry if i've put a stupid topic.
