....it's the color in the pictures I want to gradually reduce the saturation on until they are black and white before the transitions start, not fade in or out to a black or white screen like you are suggesting.
Sorry, but I wasn't suggesting that you use Fade to Black or Fade to White, just explaining what they do, given that you used the term "fade" in your first post. I assumed you may have been using the Fade to Black transition (which won't achieve what you want).
I suggested that you use Cross Dissolve, but I need to explain further how to achieve the effect you are looking for. First, you need to place a copy of the photo directly after the original. Make sure Ken Burns is turned off - use Fit. Now double-click on the copy to bring up the Clip Inspector. Click on Effects and select Black & White, then click Done. Drag a Cross Dissolve transition between the 2 clips (photos) and adjust the duration to your liking in the Inspector. Now you will see the effect your are looking for.
The key is to have an exact copy of the photo following the original, then change the copy to Black and White (or Sepia or any other effect), then insert the Cross Dissolve (or Cross Blur etc.) transition.
Hope that''s what you are looking for!
