AVI is only a container metaphor. We don't know what
codec was used by your camera and/or your capture
process? We also don't know what kind of camera you
are talking about? Can we assume it is a real video camera
and not video from your phone or from a still digital camera?
Is it a DV camera? Did you use Firewire to capture, etc?

Sounds like a problem with interlace and field sequence.
Try reversing the field order.

If we assume that your AVI is from a DV camera,
and the MPG2 is something like what is used for
DVD discs, then by definition MPEG2 will look
worse than DV-AVI because it has a great deal of
video irretrievably compressed out of it.
