Is it then so that the offset with in/outframe is in frames, so with 25 fps we have to calculate for 1 minute, 1500 frames...

But what if I have a kind of preshow, before a movie starts. I like the movie to start at 1hr, 0min,0sec.... and before that, at 55min,20sec orso i want to start a few clips and other things.....

Does Catalyst handles this automaticaly in the right way then, since you say that movie length is limited to around 43 minutes.....??????
