Do the frame rates match? Did you check this in another browser/ on another computer? could also be a simple performance issue.
Yes I did try it in other browsers and still see the same thing... Weird... I have looked online and read docs, etc and haven't found anything on this yet.
Can you provide the AE source project or the XFL and for reference the SWF you produced somewhere? Seeing what's in there might help to track the problem down.
Here's a test file that I have been using to try and figure out why when I open the .xfl file in Flash that some of the frames are missing...
Attached you will find a screen capture of what I am seeing in each of these.
The AE file is 3 layers that are jpg files and the overlap that you see below is a dissolve from one to the other. The other file showing the timeline in flash shows the missing frames after the first dissolve occurs between layer 1 and 2.
I am sure there is something that I am not doing correctly - so any thought that you might have are greatly appreciated!
I found out what it was...
I had to reverse the layer order and after I exported to flash as an .XFL file - it worked...
That was the issue...
Thanks for you help and input earlier!
