I see ripples

[Ham]

VirtualDub information about the movie is attached.

Everytime I play this movie, I see these horizontally layered ripples that appear sporadically and in frequent intervals in the picture. The ripple's texture is like a ripple over water.

What is causing this, and is there any way to fix it?

Thanks.

Can you post picture(s) of those 'ripples'?

[Ham]

Sorry, you can't really see the distortion from the still captures, but they occur in areas of the video where there's a lot of fast motion.

Any ideas?

Could they be interlace lines? If so, they can be easily removed using a Deinterlacer.

[Ham]

Which program do you recommend for deinterlacing, and does it require recompressing the movie?

Thanks.

[Enchanter]

Virtualdub has its own Deinterlacer filter (or you can opt to download the more versatile Smart Deinterlacer filter from Donald Graft's site). And yes, you will need to re-compress the video when deinterlacing.

Cheers.
