	# Config variables
	SIMILARITY_THRESHOLD=25 # A slide change is assumed iff frames PSNR similarity falls below this value
	FRAME_PERIOD=30 # [Seconds] Duration between sampling times
	CONVERT_TO_PDF=0 # Set to 1 to make pdf. Might cause errors if imagemagick is not configured properly. See https://askubuntu.com/questions/1081895/trouble-with-batch-conversion-of-png-to-pdf-using-convert
