Hello,

I have created a diaporama of 228 pictures,
The delay of display is 5 sec so the length of the diaporama have to be about 19 minutes.
But it is not, the length is equal to 10 minutes.

Regards,

are you taking into account the time of the transitions between the photos?

Yes. The diaporama stops after the 120th picture.

I can confirm this. Will maybe have a look at it this weekend.

After hours of looking into this it should finally be fixed in svn rev. 4719. It was also not possible to set image, color and title clip durations higher than 15000 frames (in your case = 10 sec), but their size could be increased later in the timeline.
