When a particular alternative format for a particular content item is requested for the first time, Ally generates this on demand. In most cases, this completes within 1-2 minutes.
As soon as it has been generated, the alternative format is downloaded. Ally then also caches the result, so any additional requests for the same alternative format can be served and downloaded from cache immediately.
