Yes, I noticed it too. The reality is, that any color balancing algorithm uses some criterium to balance the colors. Mine is no different. The second reel has a lot of red/orange in almost every shot, and almost no green, meaning that the colors are pretty biased, and therefore unbalanced:

It’s very difficult to find shots with sufficient amounts of red, green, and blue to calibrate the algorithm. I’m trying to figure out a way around this, but this is a bit of a challenge. The current algorithm is less sensitive to this problem, but as these shots show, apparently still too sensitive.
