Stripes/lines in motion.

In the movie above you see some stripes/lines near the arms when the guy starts flailing/moving them. I would like to get rid of these without re -recording it if possible. Could someone please help me with this?

The source:
DV-PAL -format 720x576x24 25fps interlaced

The compression used:
It's a mpeg-1 compression using Video rendering quality "Good", frame rate 25, aspect ratio 1.0,i-frames 15, b-frames 2, Video buffer 0, Video quality "high", Insert sequence header before every GOP "checked", Write sequence end code "checked", Constant bit rate (bps) set to about 400 000, audio off. The rest default.

Is the info given here sufficient or should I try to explain further what it is that I would like to have done?

Sincerely, Fred.

Is it possible to do this or can't Vegas 5 mpg1 compressor handle these types of movies?

For some reason I cannot get it to play but not to worry. Two things.
1) The mpeg-1 encoder that ships with Vegas is far from the best. Get a copy of TMPGEnc, I think for mpeg-1 only it's still free but you might have to dig around their web site a bit to find that version. Even if you buy the full version with mpeg-2 it's pretty good value and it's more than just an encoder.

2) You're almost certainly starting with interlaced video which is being displayed on a progressive scan device so you'll get interlacing artifacts. Best solution fro web content is to shoot progressive scan but you'll need a camera like the DVX 100 or the GL2
If you don't have access to one the best solution I've found is to convert to progressive scan in Vegas, render out to new AVI and encode from that. In project properties change field order to None, try Deinterlacing methed as Blend. If you don't like that then try Intepolate. Interpolate will give you no motion blur BUT will knock your vertical res in half. If it's only for low to medium res web streaming I wouldn't loose too much sleep over it either way.
If you want very high quality at full res send to to someone with a S&W box that does motion compensation but be prepared for a sizable bill.

Hope this helps.

Thanks a lot Bob, that interpolate tip really made my day!
