I’m not sure if you have seen this documentation:
You will want a different workflow if you use Shotcut.
Here is what I suggest:
- Put all the images in the playlist
- Use the playlist to put the images in order (did you know you can “play” the playlist?) and remove images
- When you feel good about the number and order of images, select them all and launch the slideshow generator
- Choose the transition settings and duration
- Generate the slideshow
- What to change something? Delete the entire slideshow and go back to #2 above.
- Keep regenerating the slideshow until you are happy with the result
