how to record avi file in relative small size

i try to grab picture from usb camera and save to AVI file. but the file size are all relatively too big. I hope to use xvid filter that can support good quality and good compression. But for the AVI filter list can not list this filter. So i hope to ask how can i use this filter in the labview or what kind of other filter which have same function can meets my requirement. 

I once asked the same question and got some feedback. So hope this question can be solved.
