The mac I used for this video is ancient so the quality isn't that good D:. Please watch it in full screen to see the process

Due to security changes in Catalina, you may have to manually allow access to vapoursynth before installing.

Open terminal and run the following command:

sudo spctl --master-disable

To enable gatekeeper again:

sudo spctl --master-enable
