Work-in-progress document. These notes are loosely arranged and named. Take what you may. Thanks to @garciadelcast for contributing with his discoveries!
Here is a guide with personal notes to use FFmpeg and Imagemagick to automate all kinds of tricks in gif creation, video conversion, frame extraction, image processing, and more. These notes express a love for automating the automatable.

At April 8, 2019, the specification of Google Apps Script Project was changed. You can see this at Google Cloud Platform Projects. The official document says as follows.
Warning: Starting on or after April 8, 2019, the Google Cloud Platform Console won't be able to access the default GCP projects created for new Apps Script projects. Older, existing scripts may have default GCP projects that are still accessible, however. If you have a new script and require access to its GCP project from the Google Cloud Platform Console, you must use a standard GCP project.

| * This script expects the global variables 'refresh_token' and 'firebase_api_key' to be set. 'firebase_api_key' can be found | |
| * in the Firebase console under project settings then 'Web API Key'. | |
| * 'refresh_token' as to be gathered from watching the network requests to https://securetoken.googleapis.com/v1/token from | |
| * your Firebase app, look for the formdata values | |
| * | |
| * If all the data is found it makes a request to get a new token and sets a 'auth_jwt' environment variable and updates the | |
| * global 'refresh_token'. | |
| * | |
| * Requests that need authentication should have a header with a key of 'Authentication' and value of '{{auth_jwt}}' |
