Just made a Clip I used in Microsoft support and when I played back the clip blinks on and off. I had edit a section or to of space nothing happened but to make run a little slower I ended the play time.
Strange it's working perfectly here, but in the Mac forum, it's blinking. Strange. But it is demonstrating a Problem I had for a long time. Where after my clip ends it automatically starts running another movie which I don't want.
