bad quality with dvgrab

Hello, I've just tired to import dv files from my Panasonic NV-GS 8 digital camcorder to my linux laptop via kino and via dvgrab ( which kino uses anyway). I get the clips but in a very poor quality ( the pictures gets striped when there is any motion). I tried the settings in kino but it didn't improve at all. Is there a way to improve the quality of dvgrab or use another program?

It's not DVGrab or Kino that is 'striping' the video. It's interlaced. You can feed it through mencoder to deint or any other deinterlacing application, but that's probably what the "striping" you are seeing is.

In the simpliest way possible of imaging it, dvgrab is just grabbing the 1's and 0's from your tape and structuring them with a file that is usable on a computer (for editing I'd suppose), so it's not doing anything that your camera didn't already do

As stated above the video you are using is interlaced, by deinterlacing it it will look normal on your computer screen again. You wont see this interlacing on a TV but you will on a computer monitor.

Thaks a lot. Everything works just fine.
Sometimes the simple things are the problem.
