In internet-scale systems complex delivery systems involving transformation and caching are not necessarily a win for performance insofar as once you give up a millisecond of latency you cannot get it back. You very much can get a win out of a CDN but somebody has to do aggressive tuning of absolutely everything.

It's not for performance but for not having to permanently store terabytes of differently encoded data.

You could possibly also pre-populate cache - all new media files get sent to encoder and cached preemptively, and if they are popular enough they just stay there till they are not.
