Resize photo slideshow to match audio track

[grzltn]

Hi all, I am going nuts! Last year I made a funeral slideshow where I added a bunch of photos to a music track, set the transitions and I found a way to auto scale the slideshow to match the full duration of an audio track. Sadly I need to do another funeral but I cannot work out how I did it! I read the forum, reviewed a bunch of YouTubes but cannot find the elusive clue.
There are some 155+ photos and it is a work in porgress with them being added and deleted - I really do not want to edit the list to match the sound tracks … Some quick assistance would be appreciated as the funeral is in 4 days … ty in advance.
Warmest, Lex

• Add you audio track to the timeline
• Add your pictures to the playlist
• select all pictures in playlist
• Add selected to slideshow
• Play with the duration of each picture until tje slideshow duration match your audio track lenght

for a funeral a would think that a min. duration at min. 5 sec and transition at 2 sec, you don’t want the pace to be high, then it is better to reduce the number of pictures or increase the length of the audio track.

Example:
Audio track of 15 minutes (15m x 60s = 900s)
900 seconds / 155 pictures = 5.8s + 2.0s (Transition duration) = 7.8s
