1. Download Hypercam 2 Unregistered Version (it's a free program) or another screen recorder of your choice. There are several good ones out there. If you have more questions about it, feel free to send me a PM and I'll give you a step-by-step explanation of how to use it.

2. You can lip sync by either typing in local or making a movie while in-game; I would go to a private map for this sort of thing. Just play around with it and see what works the best. For longer sounds while singing lyrics to a song, put more letters such as "youuuu" for a long "you." Understand? c:
3. You will most likely NOT be able to get the lip syncing perfect, but editing in WMM can fix that.
Hope this helps!
Again, don't hesitate to PM me if you need more help. I'll be glad to help you out in any way I can. ^^ Good luck!
