Black flash after transitions

Using iMovie 6, sometimes there is a black flash at the end of a transition (working with photos). Doesn't happen on every transition and doesn't happen all the time. I work in an elementary school computer lab and it happens randomly on all 30 computers. (iMacs 10.5.8) I just put together a movie with about 30 photos using the same transition (cross dissolve) between each one and it flashes on about half of them. Any suggestions?

MacBook, Mac OS X (10.5.8)

I had the same problem but with white flashes. Somebody on this forum helped me solve it...

First remove the affected transition. Then highlight a different clip (not the beginning or ending clip betweeen which you want the transition). Then drag the desired transition from the pane between the two clips. The transition re-renders and most times this clears up the offending white or black flashes.

But then it stopped being a problem for some reason - maybe the last update of version 6?

Michel gives good advice. I would just add that extracting audio from the two clips before applying the transition is also a good idea in these cases.

Post back if you need instructions! 🙂
