Requirements (macOS):

• brew install gource
• brew install ffmpeg
• iMovie (or similar video editing program)

Installation:

1. Create a folder named gource in your home directory and save all 3 above files in there.
2. Modify the gource config in setup.sh to match your project (this is currently setup for the 8.x-3.x branch of https://www.drupal.org/project/bootstrap)

Gource creation:

1. Navigate to your project and execute ~/gource/setup.sh (this step is important as it will install the gource configuration into the project's .git directory)
2. Then execute ~/gource/create.sh (will take a while depending on how big the repo is and how fast your computer is)

Once completed there should be a new file in your project root named gource.mp4.

Post-production:

1. Take gource.mp4 and import into iMovie (or similar video editing program).
2. Add another clip as an additional layer in the iMovie project that will act as the background layer.
3. Add a "Blue Screen" effect on the gource.mp4 clip (https://filmora.wondershare.com/imovie/imovie-green-screen-effect.html#part2 or https://blogs.cofc.edu/tlttutorials/2015/10/21/changing-your-videos-background-in-imovie/)
4. Continue editing to your heart's desire until you get the desired outcome.
