The guy exported a 1 hour video to a new encoding, which took 6 hours. Isn't that expected?

To put things in perspective, read about Adobe users complaining about the same:

My only non-OS experience with re-encoding is Apple iMovie, and man that's slow! Just 5 minutes took more than an hour.

If ffmpg can use threaded encoding, we for sure should enable that though :)
