I just discovered a new version of the program for the first time in about, 9 years, and I'm wondering how I can activate them.

It is this version here: https://github.com/gispos/AvsPmod


There are two new features I see:

A "Snapshot" feature, that says "Make 1/Show 1" and "Make 2/Show 2". Not really sure what it does exactly.

I also see 2 new additions to the ConvertToRGB/Convert to YV12 filter. Two new options labeled "Rec.2020/PC.2020, but they won't activate. Any way I can find out information on this? I'm very excited to use a new version of this program after nearly a decade.
