Download Fraps,trial or full version( you haz to buy it),use an editing program such as Sony Vegas,but again is not free,so try movie maker,watch some tutorials on youtube
and Voila you haz new video x3,it takes a lot of things to know
here is a list with TB commands that are useful when making a video
/opt uke 0
/opt hud 0
/opt bruise 0
/opt trails 0
And of course use FreeCam,search for freecam on the forum ( it is already included in TB) so no need to dl or buy.

If you need more help,you can PM I'll give you a more detailed list.
Also,I suggest you to START with Movie Maker because it is easy to learn,but the results aren't that great,and maybe then try to use Sony Vegas or After Effects because it's more complicated stuff you need to know,so use MovieM for learning the basics.Good luck!
