I'm using version 0.7.7.1 with Suse 11.2 64. I've created several profiles, with different durations.

It seems to me that the general settings for the durations are overriding the profile settings.

In the General settings i set the duration for imageclips to 32.
I create a new project and load a profile with a duration/framerate of 16.
I load the image-clips into the Project Tree, and the duration is 32 instead of 16 as specified in the profile.

Is there someone who has a solution? Thank you!

There is no duration in any profiles. The duration in the Project Tree is not important. You can adjust the duration easily by placing it on the timeline and resizing the rectangle.

Ok, thank you for your answer, that's clear. But what is the purpose of the framerate setting in a profile? I was thinking it was the same as the duration between clips.

Take a look at this one:
