horizontal lines after capture

[traveller]

Hi all,
I've just captured video using Huffyuv v2.1 (Marvel G400).
When I play this movie I see horizontal lines like frames have not correct order(?).
After uncompressing situation is the same.
I've tried to compress to mpeg2 with Ligos-the same.
Only when I'm using Panasonic encoder with option:
"Interlace Processing-Use Event Fields"
it works fine but Panasonic has not mpeg2 format.
What should be done with captured file to have normal movie which could be simply encoded to mpeg2 ?
Boy,it took me half a night so maybe it is any solution :-(

Great thx for any help

Gonna take a wild guess here, but if you're seeing this a lot in high-motion scenes, chances are you're looking at raw video data, and the horizontal lines effect is the byproduct of a TV feature called "fields." If you think of TV running at 60 frames per second, and think of how you would get those 60 frames to fit into 30 instead, you've got the idea.

I made a big post about it before <a href="http://forums.murc.ws/ubb/Forum2/HTML/003400.html">here</a>. One correction: the reason we have fields in the first place is because flashing bright pictures at people at 30 frames per second let them see gaps between the frames. Compare this to the dark movie theater, where we can get away with 24 fps. So we upped the frame rate by inventing fields.

Great thanx fluggo99 for explanation.
I've read everything you wrote and now I know what I'm writting about.
Only one thing to be clear-as film which was captured with Huffyuv has such "fast moving" effect,was "rescued" with Panasonic "Interlace Processing-Use Event Fields" option is any practical possibility to improve original file before conversion to mpeg2?

TIA

You mean, "How can I get rid of these horizontal lines?" or "Is the way I did it OK?" Several products have de-interlace filters, all should solve your problem. Panasonic's "Interlace Processing" sounds like one, so yes, that would be the correct way to get rid of them.
