Transitions are New Blue transitions ultimate 5 with studio 16 platinum , what else is not clear? Its simple , add pictures to timeline to make a picture movie , lets say 10 pictures spaced at 5 seconds, drag a transition to picture and add it. Now play movie . The transition is not working correctly when viewing until you re watch the video 5 times. Each time through playing it gets better. I've used older versions of this software for at least 10 years with out this issue . Anyone with a good knowledge of this software I think would understand and hopefully help.

I just installed new studio 16 platinum on my computer. if I make a movie with pictures and use transitions between each picture, the transitions are hanging up . Kind of flickerish, after playing through the movie maybe 4 or 5 times they will smooth out in the viewer. even the transitions in the transition box where you selct them hang up. You can select like media then go back to transitions and put curser on them then they are showing what they are in movement again .Help please

This is a video, using first settings it would never smooth out and as you can see second settings it will after 4 or 5 times playing through.

1st settings never smooth but second will after a few times playing through

look normal to me, it's temporary computing and memory issue.
