Strange artifacts on DVD playback | ||
| polara64 posted 2009 Sep 11 11:01 | ||
Am trying to rip an unencrypted DVD of a band documentary. Am getting what looks like horizontal scan lines in picture when I play DVD or ISO of DVD in VLC & MPlayer. DVD plays normally (without scan lines) only in Cyberlink PowerDVD. Have tried ripping in Handbrake but getting scan lines. Any idea what is causing this and how to fix? Thanks.

| You have interlaced video. Use the deinterlacing option in your player(s). For example, in VLC, while playing, right click on the window and select Video -> Deinterlace -> Bob (or one of the others). | ||

| I think you called it! Deinterlace>Linear in VLC removes about 80% of it. But in Mplayer, Deinterlace>Yadif (double framerate) gets about 98% of the way to perfectly clear normal playback. Will work with this in handbrake. Weird, never had anything like this on a retail DVD before. Thanks for super-fast and helpful reply!! | ||

| MOST retail dvds are progressive scan, not interlaced | ||

| Some retail dvd do have interlace because they were done by cheap methods by cheap companies.If you are going to watch the dvd from your tv there is no need to de-interlace.De-interlacing will reduce your picture quality by getting rid of 1/2 the fields. | ||

This is true for movies and recent digitally shot material, but not for a lot of stuff shot on video through the 80's and 90's. | ||

| Problem solved. Used the Decomb method in Handbrake as outlined here - http://trac.handbrake.fr/wiki/DeinterlacingGuide |
