Of all my years of using Adobe After Effects, I have never encountered this problem before. First of all, this is what it looks like when I'm normally editing in my composition.
Click the image to view in a higher resolution.
When I add this composition to the render que, with all my settings ready, I hit render.
But while it's rendering, I just get a red screen.
In case you're wondering, these are my basic rendering settings.
These are my output module settings.
And these are my composition settings.
