Hi all:

My problem: I've dropped an mp4 video on the Timeline and it plays fine. After I cut the segment out that I want to keep and Produce
render it, the render comes up blank and nothing plays. The render/produce goes as it always has and it's rendered into an mp4.
It's been a little while shince I've done this but I have done it many times before with no problems.
Am I missing somehting?

I'm using PD 19

Thanks for replies
