If you're going frame by frame wouldn't the red light have to come on after the camera flash? I wouldn't expect it to come on during the flash.

Step through the Mason video. The red light comes on 8 frames after the first flash, and 5 frames after the second flash. That's not just "after", that's a *significant* delay. Also, it's been noted that each frame represents a fair amount of time. The timing system is dealing in thousandths of a second, so I would imagine that it IF the flash was the culprit, it is very possible that its results could appear in the same frame, if not the very next frame. 5 frames? Don't think so. Again, it also appears that there aren't any cameras involved in Brand's incident. Camera flashes may just be a coincidence.
None of it explains why the red light comes on BEFORE the pre-stage and stage lights go out in each instance.
A poster on DRR mentioned they had this problem frequently at their home track:

At my home track, this very same issue kept showing up in the right hand lane, DURING eliminations only. The track at first blamed it on the driver rolling forwards or backwards out of the beams. Then looked for cobwebs, ants, sun reflection etc. Then after much logical, thoughtful incise and concise gentlemanly discussions, accompanied by arm waving, four letter words, threats of violence, promises to never set foot on the grounds again, and other civilized, illegal actions, somehow an answer was found. it was discovered this only happened during eliminations, only in the right lane, it was random, not a common occurence. A lady that used to run the compu-link system for the track, suggested that they turn OFF auto start during eliminations, and see if the problem went away. IT DID!!

We had a different issue at the bracket finals at Rockingham a couple of years ago. We had numerous errant runs. I was announcing and noted the anomolies before racers even got to the tower to complain. We stopped and replaced one or more photocells on the starting line (that had just been replaced a week or two before). Had problems with the Stage beam hanging so bad it wouldn't go out at all. We turned off Stagelock, and had no more problems. Weird things happen. Maybe we think they shouldn't happen, and we maybe we think the solutions shouldn't be the solutions. Doesn't change the facts.
The most bizarre thing I've ever seen is having R/T's, all incremental times and mph matching other timeslips and making sense, but having the finish ET being off by about two tenths of a second, and the MOV likewise showing about two tenths despite the cars being separated by thousandths. It happened multiple times at the same event, with different cars. How or why it happened, I have no idea, but the only plausible explanation I could come up with was that somehow the finish line sensor "missed" the front wheel, and was triggered by the back tires. A car length was roughly the amount of ET that was "missing".
