So, I followed the tutorial (https://scaper.readthedocs.io/en/latest/examples.html#examples), but it gives me the following error: AttributeError: 'Scaper' object has no attribute 'reset_bg_spec'.
So I changed sc.reset_bg_spec() and sc.reset_fg_spec() to sc.reset_bg_event_spec() and sc.reset_fg_event_spec(), the script is running without problem.

@mia-mia-w thanks for this. I was wondering why it didn't work!
