So I've got 3 tracks that I've motion tracked and done my work to, but for all 3 theres the same issue; The background video looks fine in the "Rendered" mode, but when I render, it appears to have double the intensity of the original video file.

For 2/3 clips I was able to, by some miracle/messing around with render layers/masks, fix the problem. This 3rd clip however, is not working at all. I want to know if this is a common issue and learn the root of the problem.

Thanks so much!

So for this clip, I was able to fix it by turning off and on all the render passes (Z, Combine, Vector)... strange that it worked since I didn't actually change anything at all. Must be a small bug, no matter since it's easy to fix!
