I have been processing holiday pix and I thought I was about to finish the project when I found the last 16 minute slideshow (#10) made in FCP has a problem after I have exported to QuickTime. Although the project looks fine in FCP it doesn't after I have created a QT movie. The problem occurs anywhere I have dragged a transition from the effects tab to an edit point in the timeline. If I use a 3 second transition between two clips , the first clip goes black for one frame around 40 frames from the end of that clip . This creates a brief "flash " of black each time there is a transition whilst watching the movie. The first 9 films processed fine and I have checked to see the settings I am using are the same. I have re-built the movie in FCP; downloaded the last Pro Run Update; re-started the computer etc , etc over the past two days. It seems the problem is with QuickTime and I am wondering whether I have processed Film #10 after installing the recent Upgrade (7.1.6) and that the cause may lie there. I suppose one way of getting around the problem is to go into QT Pro and delete the offending clip from each affected transition. Anywhere I have used the pen tool to create a fade there is not a problem. I have run permissions in Disk Utility and also Cocktail to clear caches and run cron-scripts. I have 63 GB free space on my external HD where the project is stored. Any clues guys before I go even balder? Thanks, Ian Tucker
