Video plays at different speeds
Hello: I am inserting .mp4 video clips in storyline, one clip per slide. there are fifteen clips total, averaging between 1 minute to about 3.5 minutes each.
When I play a few times in preview, the video plays fine for the correct length of time. The slide advances automatically, which is what I want. The seekbar works fine.
But then, when I work on the course later, the video plays fine, but then there is extra time left on the seek bar before the slide advances. So, video stops playing, then there is about a minute left on the seekbar and the screen is black. After the black plays, the slide advances.
Then I have to delete the slide, create a new one, insert the video - then it plays fine again.
Any ideas? This has occurred several times with several different clips, Seems like they start having problems after a while. I am working off of my hard drive, not a network.
