I am trying to run a Python program that generates visuals from an audio file. I'm a bit of a beginner here, so I've just been reverse-engineering issues and incompatibilities that have come up along the way.
Now, I am faced with an error. The program runs successfully but when it attempts to write/save the output video file, it gives me multiple tracebacks and a a 'TypeError' at the very end:
Traceback (most recent call last):

TypeError: must be real number, not NoneType
My understanding is that each of the listed files and lines within them are giving the same error? Or does the TypeError at the end only apply to the most recent (lowest) file reference?
Would love to figure out how to resolve this. Somewhere in these file(s) a number is being referenced incorrectly, it seems.
Thanks so much for any help!!
I tried diving into the most recent (lowest) file called 'ffmpegwriter.py' and I went to the referenced line. To me, '%.02f' looked like it might have been formatted incorrectly, so I tried adding a 0 before the decimal, but same error.
Not sure where to look...
