Yes, wavy lines or static can play havoc with the detection. If you have a noisy signal, the "blank" frames won't seem blank since they may have very dark pixels and a some very light pixels so the code won't pick them up. I tried to work around this one time by assuming the frame was blank if only X% was light while the rest was dark, but that caused false positives as well like for instance a nighttime scene of people driving in a car where most of the frame is dark but there are a few light spots. It's definitely an art but getting better over time I believe. -- Chris
