Ask HN: Facebook Lookback implementation
Probably a noob question. But whats the best practice for Facebook, and others like JibJab for streaming dynamic videos based off templates? Is each view dynamically created? Is a video created upon the first request and cached for each subsequent playback?

The video doesn't change and it was pretty fast when I first viewed it. At Facebook scale I'd guess they have to generate the video in advance. Would love to hear from anyone who worked on this feature.
