Stringing Tiff files together

Horribly green, but learning…I have created tiff files of six pages of music. I’m trying to synchronize the files with the music (audio). I need to slow down the tiff files progression.

In properties, there is “duration” but it has no effect at all… Where am I blowing this??

Hoping someone has experience posting music as a video on social media. That’s my goal.

Many thanks

Just make a video of the tiff file progression.
Then slow down the made video to the music.

To adjust the duration of an image clip on the Timeline you must drag its right edge. The Duration field in Properties can only be edited when the image is in the Source player before adding it to the Timeline.
