Ghosts/Flickering in one stream

[beartums]

I am having a problem with the converion of one avi to mpeg-2 for dvd. While the AVI looks fine, the mpeg-2 stream seems to flicker or have slight ghosting during fast motion (of which there is a lot because it is a video of a martial arts test).

The unusual thing is that a video shot from a different angle does not have this problem. The second angle video was captured from VHS through a canopus advc100 (firewire). The first angle (ghosting in mpeg-2) was captured direct from a mini-dv cam (also firewire).

In the past I've done exactly the same thing (two angles, one from vhs and one from miniDv) and had not problem with the video quality. I find this very weird.

Also, I don't know if it matters, but the gis are considerably whiter in the first (ghosting) video because they are reflecting more sunlight. Whould it help to reduce the contrast on the avi file before encoding?

Any pointers would be appreciates.

thanks,

Couple of things:

Make sure you have the field order correct; bottom field first for DV.

Second; make sure you have the correct frame rate set; 25fps for PAL, 29.97fps for NTSC.

Which encoder? PAL or NTSC?

A screengrab would help. also .

Use a software DVD player with deinterlace OFF (or "Weave").

Thanks iantri,

It turns out that for some reason the vhs cap was happening "interlaced" and the dv cap was not (or the other way round). When I changed the TMPGEnc setting for the DV cap to "non-interlaced" everything looked fine. I don't know why or how, but the quality is back where is should be and I'm glad for that.

Thanks for the input.
