Dip to black uses transparant layer
For some reason when im using Dip to Black, like i have done many times before, at the end of a clip or the start (not as a transition between clips) it goes from black ( the time line with no video playing) to transparent before fading into the video as the screen shots below demonstrate.





This has never happened before and I don't believe ive changed any preferences either. It would be greatly appreciated if anyone could trouble shoot this. As a temporary fix ive used a black colour matt with a cross fade between clips but id much rather the dip to black effect to work normally.
Many Thanks,
Harvey
