I'm encoding an anime DVD to XviD, doing 2 pass, and when I watch it after it finishes, every time there is a scene change a white-ish blue-ish line appears along the very bottom of the file. I've never seen this before and i'm not sure what i'm doing wrong. My .avs file looks like this:
LoadPlugin("d:\rip\GORDIA~1\mpeg2dec.dll")
LoadPlugin("d:\rip\GORDIA~1\InverseTelecine.dll")
mpeg2source("D:\temp\episode01.d2v")
InverseTelecine(40,10,15)
crop(0,2,720,475)
BicubicResize(640,464,0,0.75)
The only filter i ran in virtualdub was the subtitler by Avery Lee. My XviD settings looked like this:
Global:
Motion Search Precision: 6 - Ultra High
Quantization Type: H.236
FourCC Used: XVID
Max I-frame interval: 300
Min I-frame interval: 1
Quantization:
Min I-frame quantizer: 2
Max I-fram quantizer: 31
Min P-frame quantizer: 2
Max P-frame quantizer: 31
Two Pass:
I-frame boost: 20%
Below i-frame distance: 10
I-frame bitrate reduction: 30%
High Bitrate Scenes: 25%
Low Bitrate Scenes: 10%
Bitrate payback delay: 250
Payback: with bias
The rest of the settings i didn't mess with. I'll include a picture if i can get it hosted somewhere. Any help is greatly appreciated.
Here's the picture:

Interesting. Can't say I have ever seen it before. But so other people might help you what Xvid build are you using? It appears to be a major fact you left out. |

Actually, I've seen the "garbled-lines-appearing-on-the-bottom-of-the-frame-at-nearly-every-scene-change" bug with some Anime DVDs, but in my case the line was always yellow-ish. To this day I don't know what causes it.
You might try posting this at Doom9, since there are a lot of experienced DVD rippers there.

I'm using XviD 27.11.2002.0020, the latest stable build. |

Okay, it's not XviD, because I examined the vob files and they have the same line along the bottom of the frame, so the problem is obviuosly in the ripping process. |

It might be a part of the data itself. A TV screen hides the borders of the image (as in: the image is larger than the visible part of the tube), so you would not see it there. |

This is called anologue anime. I don't know what exactly causes it but this comes from the cel scanning process most probably. Usually you also see that the picture is tilted slightly when a scene change occurs, and that it gets rightened over the following frames. It's just cause they weren't being careful with placing the sheets on the scanner. The cheaper the anime, the more obvious this is. Ranma is a series that SEVERELY exhibits these things.
