OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

event.requestContext.identity.cognitoIdentityId should be the user id
Cognito User Pools are for handling user registration, authentication, and account recovery
Cognito Identity Pools (or Cognito Federated Identities) are a way to authorize users to directly use the various AWS services in your account, such as S3, DynamoDB, and, most relevant for APIs, API Gateway
