When I export a slideshow in MP4 format the saved file shows different images in Windows and Adobe Bridge and neither is the first image of the slideshow. Is there any way I can designate that the first image shows when viewing (not playing, just viewing in folder) the slideshow file? Or does it even matter when uploading to Youtube? I know Youtube selects an image to face the slideshow somewhat randomly and I wanted to try to designate an image to face the file on the computer and see if that would help with Youtube's selection.
Hope this question makes sense. I'm not sure I'm describing this correctly. If so, anyone have any suggestions or is it left totally random.
