How to get rid of these lines?

[sascha.koerber]

Hello Friends,

my boss gave me some mpeg-movies on a dvd and asked me to re-arrange them to a presentation. the problem is, all of the movies are of an awfull quality and all of them show lines (see attached snapshot please!) all over the screen when theres rapid movement.

For i am a newbie in all that encoding stuff, i don't know how and if i can get rid of those disturbing lines. I reencoded some of the movies using TMPGEnc. In some of the videos the stripes are gone, in others not. What can i do? I would be grateful for any help and any advice where those stripes came from.

It's called interlacing - look it up in the glossary. You won't see these when you play it back on a normal TV, but you will on a PC because of the difference in display methods. If the final presentation is on a PC then you can deinterlace, however the usual result is a drop in quality to some degree. If they are being embedded in a powerpoint presentation od similar, you don't have much choice but to do this. If you can play them back independently then you would be better off using a player that deinterlaces on the fly - PowerDVD, VLC or Media Player Classic all do this.

Hello again,

thank you guns1inger/Abond. That answers all my questions. Burned the stuff to a DVD and reviewed them on a DVD-Player and - look - all stripes are gone. Well - one video still shows some bigger stripes, but i guess thats just because of the crappy rip from VHS. Will have to live with that then. Thanks at gun for the excellent and unterstandble answer at that point.

Did you crop and resize? That would cause "bigger stripes" if you didn't do it correctly. If you want to get rid of noise at the edges of the picture mask with black instead.
