Here is a sample of how I am using the UserMedia object right now:

If you were to drop a ball in front of your phone's camera, you would see a substantial amount of motion blur at the standard 30 fps mode. If you enable the highest frame rate on your camera and record a "slow motion" video the resulting video frames have significantly less motion blur.
Ashley, would this be a feature request? Maybe the ability to request higher frame rates in the UserMedia -> Request Camera action?
