How to change option?

When I create a diaporama, some values are proposed by default. Of course I can adjust those values. In my case I accept the default values but while making my vidéo I want to modify for some pictures the value of duration of transition. I don t know where I can get and modify this value. Thanks by advance.

After you generate the slideshow, you can edit the transition length by dragging the side of the transition in the timeline.

Hello @brian,

Below a screenshot of my video :

The cursor is positioned at approx. 1:45. I select the picture (highlighted in red).
I want to put the transition value to zéro (see below, fourth value) and also the duration of the clip to 1second.

After the video is generated I can’t access again to these values. Can you help me ?
