Thanks Walter. That sounds like a good solution, but I have a new problem: if I set the still frame duration in 3 my imported still is 2 frames, if I set it in 5 is 2 frames, if I set it in 8 is 6 frames, so: no the order I give to FCP never match with the resoult I get. Why is this happening and how can I solve it.
Thanks both Walter and Chris.
