Need help with a video

Okay,I use camtasia..and i extract it into a .avi to post on youtube since they don't support camtect blah blah...if i use windows movie maker or camtasia editor and i add music titles or anything,it changes the type of file format..and I can't drag and drop from lime wire either..can anyone help me?

 

didnt we already answer this for u

 

What are you using to add titles? Imovie? or that windows program that works like crap and is a huge joke?

 

he uses camtasia which saves the files as .cam or some shit basically get adobe premier and hypercam

 

dude I know how to post them..I already posted about 6 vids..I need to know how to edit..when i edit them with windows movie maker or camtasia editor it turns them from .avi to different file..

 

dont use movie maker its crap seriously get premier cs3 or something.
