The selection is available (cross dissolve front and back layers), but it is not effective. Does not work. Even the first selection "Dissolve front layer only" does not work....Any ideas????
EDIT: answer discovered...my picture were long (appr 2 minutes) and i need to reduce them down to 3.5 second each.
If you trim your layers to a reasonable time then use sequence layers and pick the offset things should work just fine.
