Hi Kevin,
I do know that short cut. I think that I used it, but could be wrong. I rendered it by adding it to the render queue. It was set for Best settings and Lossless and 1920×1080.
I already put it back in my sequence, and have more than enough resolution to make it work. Next time I use it, I will go through these exact steps before I start to make sure that this doesn’t happen again. Thanks very much for your help…Ian
