NEED HELP WITH RENDERING

Hey users,

I recorded some cool frags in call of duty 4.

I recorded it with avidemo 200, and i use virtual dub to.

Then i rended the same with sony vegas again.

The time is 51 seconds but i still got 791 mb, and this doesnt be good.

I think i made some misstacks pls add me in xfire: xtz67

Or descibe how i have to render, like which codec i had to use and so on, i used the HUFFyuv codec, i dont get it with x264
