-Warning: iPhones (as of 3S) can apparently only accept video up to 640x480. (Maybe? Double check.) If this is true, we may want to also export low-resolution versions and have a link to a different place to view the videos for lower end devices.

By default ffmpeg seems to use a number of threads equal to the number of cores you have minus 1. You can speed things up by specifying your actual number of cores. For example "-threads 2" forces 2 threads.
