Matinee Won't Use Specified Capture Resolution

Like the title says, I’m trying to export out a matinee movie but it refuses to use the capture resolution I specify.

I’m trying to create a 1920x1080 movie, but it always defaults to my screen’s resolution of 1680x1050. I’ve used both AVI and BMP sequence and both are the same. Interestingly, it WILL export a 1920x1080 BMP for the very first frame/image, but will export the 2nd frame and beyond as 1680x1050.

Are matinee sequences stuck on whatever resolution your monitor is?
