You'll need to experiment to find the right value for the variable 'alpha' in the script. This controls each frame's opacity: too high and it will be overexposed, too low and it will be dark. It's roughly in the range 5/n to 40/n where n is the number of frames in the video, but depends on the film's overall moodiness too. If you're going to run it on a feature film length video, I suggest making a low-resolution version (e.g. 144p) and fine-tuning alpha on that, since it will be significantly less frustrating.
