Some quick answers:

1. The style is called Disco Funk.

2. I shot the video at HD resolution 1280x720. The youtube did its own conversion.

3. I think I just used the Windows Movie Maker and I "eyeballed" the start of the song as close as I could. Then scrolled to the end of the file to see whether the end is still synced. I do not have a lot of time to spend on T4 due to work, kids, etc. so I had to do one take, convert, etc.
