Sounds like the jaggies. I would get them from my standard definition camcorder while panning to fast. Am presuming yours is a standard def camcorder. What program are you using? Explain your settings on import? Explain your settings on export? Most of this comes from your camcorder not able to record fast enough so you have to slow down on panning to reduce this. I have a sony sr100, which is a great camcorder, but doesn't record fast movement very well. Moved to a sony sr11 and reduced most of this. Still have to watch my pans. You can try to deinterlace. Helps reduce it but doesn't remove all of it. Its mostly the camcorder. Check out camcorderinfo.com for very good reviews and info on better ways to shoot video.
