Video transcoding is particularly suited to the cloud. This sort if unpredictable load - new titles will pop up at odd intervals - is ideal for striking the balance between speed to market (you don't want to delay releasing new titles) and cost (having extra capacity for transcoding on the off chance you need it is expensive).
Spool up hundreds of servers when they need to get a new title out, and buy them at cheapish rates is pretty much what the cloud was built for.
