I have no problem dragging still photos into the Timeline and they play very well upon Review; however, once I close the project and the program, things change. When I later reopen the program and the project, I generally find that the stills have dissappeared into blackness and won't play during Review. I have found that I can retrieve them by going to Video Options and clicking on Aspect File Color. I click on black and return to the Timeline. Upon Review the stills return and play very well again until the next time I reload Premiere. What's happening here?
