>like is there a correlation between better lighting at the start of the video and less viewer drop off (there is, have good lighting at the start of the video haha)

This gives me the smell and sight of red flags in their methodology. It reeks of unsuspected hidden variables. Such as what is really going on is that focusing on lighting in the beginning of the video simply makes people put more thought into the into thereby having a hook that keeps people interested, rather than lighting having anything to do with it.

That means this is just a pseudoscience blog of throwing darts to me. Sure call me a curmudgeon or whatever.
