First Light is only working on specific edits within an edited video file.
 

Hi David, I have an edited video I'm trying to tweak using First Light. The trouble is it's only working on a few specific shots within that edited video. Any idea why this is happening?

I have the latest Neo HD (Updated less than a week ago), and the file is a 25fps 1080P avi rendered from Vegas. I had disable resampling set for the whole video as it was a re-edit, although parts of the video had crops applied, so would have been recompressed.

The part of the video First Light does work on was originally a composite, a jpeg of a laptop with the footage composited onto the screen. But there are other parts within the video where I used the same method of compositing, but like most of the video, they're not being affected by any changes I make within First Light.
