This script creates an operator that makes every other frame of a baked cloth simulation the same, so you can animate cloth on 2s. No keyframes are used- this directly modifies the baked cache.

Use operator object.interpolate_bake.

As always, I can verify this script works on 3.6.13 LTS. I don’t know if it works on newer versions and I have no plans to test that or do anything with the extensions fiasco. Use as is if you want, make changes if you need
