Things to consider:
* VP9 is slower to encode than VP8, and a transition will require a lot of back-running of existing files. We *will* need to assign more video scalers, at least temporarily.

this shouldn't be a problem to coordinate, there's spare capacity in the appservers ATMĀ 

* I started writing a client-side bot to trigger new transcodes on old files. Prefer I should finish that, or prep a server side script that someone in ops will have to babysit?

Whichever is easiest I'd say, if people with access to it can stop/resume it as needed.

Also since some time we're tracking bytes/objects for groups of swift containers, e.g. "transcoded" in eqiad
