"I noticed there is a lack of videos featuring recording ones self while dancing"
The above statement is WAY OFF THE MARK. I searched youtube and 299 vids this month posted with these search terms "second Life + dancing". If anything it's rampant. I usualy get agro about doing to many dancing vids but it's fun :-). Go to an interesting SIM at 2 am and listen to the stream and dance. Fun and relaxing.
I was impressed with the dancing. Is that a spacenav? If so you need to adjust the feathering on it from the default. Recording at 720P is twice the fps as 1080P although I was impressed by your lack of lag. Check oout some Burlesque Shows as they have exellent dance routines and amazing sets. I recommend Guerilla Burlesque at Idle Rogue, Ellie's Burlesque or the Beautiful Freaks. Kind of an Cirque du Soleil style and they know all the dances and do lot of synched dancing as well.
Great start above the norm actually
cheers
