I have a layer of video that keeps diappearing from my final render. It doesn't disappear completly. Looks to be down to about 1% opacity. Only happens in my final quicktime render. Plays and looks fine in my comp and ram previews. All my other comps which are pretty much duplicates except swapping out 2 layers work just fine as well.
First image is my ram preview with the camera pushing past her. How it is supposed to look. Second is what actually renders out. It hits that frame right as the camera moves and she disappears. Layer order and z-position is not the issue. Any help is much appreciated.
Are you sure that you are previewing the Active Camera in the Comp?
If so then a screenshot of the entire timeline would be of much more use than these frame grabs.
I was previewing the active camera. Just to see if it would make a difference, I turned on motion blur and it worked. I've got no idea why that would effect that layer.
A screenshot of your timeline may give us a chance to help figure it out.
