Ask HN: Intro to programmatic video?

[strangecyan]

Does anyone have any resources around generating video programmatically and how it's used in the world? All specifics seem to be a closely guarded secret.

Examples would be TV News tickers, video that are clearly generated automatically from breaking news; sports broadcasting where dynamic information about the game is put on the feed or even stuff like the Facebook 'Friends Day' video where your information is put in a template?
