Dzjang:

Glad you at least found a workaround that works!
No such luck for me.
I tried your settings as shown in your screen captures,
I tried Dean's settings, I tried multiple combinations of enabling and disabling check boxes,
all to no avail.

I agree with you on the matter of the Audio Settings.
If that is the answer (if it works ALWAYS), then it should be shown in the "Make Chord Sheet Video" window.
The process should also be noted in the Help file for making a video, and a new video instruction demo made.

Hope PGMusic does some more work on it.
Luckily, I still have access to BIAB 2020 and it works fine there.

Thanks!
