What is this horrible effect on encoding?

[giggioman00]

Ok, I have a DVD ISO.
I'm trying to encode the content of the DVD for get the file at a lower size.
Anyway, everytime I finish to encode, I get this horrible effect:



This effect doesn't appear on the original video.
And this is not the only frame with this problem. All the video have this problem.
What is and How can I fix this problem?

Your video is probably hard telecined and needs an inverse telecine to restore the original film frames. It may also have blended fields that need to be removed too. Post a short sample that hasn't been re-encoded.

Looks like ordinary interlacing, and maybe a resize. The dimensions of that image are 836x464, which is not standard for DVD video.

Depending on what the source is exactly, you need to de-telecine or de-interlace the video, or keep it as is and encode to an interlaced format (without resizing).

The original video size is 720*480.
I'm trying to encode the video at the same resolution. I set 720*480 as destination and I set the anamorph.
But then the output file is encoded in 720*472. I don't know why. It's not the first time I encode 720*480 video from DVD with the same resolution and I never get this problem.

Anyway it's a vbit hard to upload a sample of the video without encoding... the file is 50 minutes and 3GB size...

Use a program like Mpg2Cut2 or DgIndex to mark a short section and extract it. What software are you using for your conversion? Handbrake's Detelecine filter may work.

I'm using xvid4psp

Ok, using a filter of xvid4psp now I fixed this problem... but now the audio is out of sync.
previously (in the ancode that had that problem) audio was OK...
why?

EDIT: Audio is ok.
Is the video speed that is incresed...
