Horizontal lines in captured video?

Hello and apologies if this has been aksed before.

I am capturing from my Sony DV cam thru Firewire port, the quality of the video seems to degrade. This is especially visible during quick pans or quick / sudden motion, where horizintal lines occur, especially in edges with strong contrasts.

Is there some fundamental problem, has anyone experienced this, and can it be avoided through settings? How do I optimize capture?

Using Vegas capture, VV3
System is P4 2,5, winXP pro

Thanks much in advance

Hi Ray,

Where do you see the lines... computer or external video?

You may be seeing interlace, which should look fine when output to video.

Hi

thanks for your posting!
I've tried a couple of things

The lines are
-> *not* in the original footage (playback from camera)
-> in the captured footage
-> in the preview window
-> *not* in rendered mp1
-> in all rendered mp2's (dvd, s-vcd)

Any ideas?

I think I might have the solution. I might have captured at a lower resolution than the rendered video, which might explain the lines (used to "stretch") in higher resolutions.

Hi colchis,

If you are viewing on the PC you are probably seeing interlace.

If you intend to display on video (TV, DVD) you might want to test outside of the PC. If you intend to display on the PC, you might try rendering "progressive" (in the custom video settings).
