What have a done:

1.Used DGindx to process the VOB file
2.Made a AVIsynth script using
Undot(), KernelDeInt(order=1,sharp=true) and LanczosResize(640,480)
3.Encoded the file using XviD 2 pass 2000Kb/s with options:
Motions search precision 4-Hight
VHQ-mode 3-medium search
and with other settings at default

And I ended up producing something that bad looking:(Video, ~10MB)

Did I do something wrong? Or is it Mpeg 4 codec cant cope with those flashing screen at such bitrate? (2000Kb/s) and most importantly, how can I improve the video quality?

Thanks

It's more than the flashing, it's also similar to the way you get heavy blocking of fog or fire. Large areas of similar color are already hard to encode, and when you combine it with rapid scene changes and huge amounts of motion, you're going to have problems. You've also got a much higher bitrate on the audio than you probably need.

You might try adjusting the keyframe boost/reduction. (I didn't look at your clip, but this comes to mind anyways)

The link to your file has expired. Can you reupload it? Also upload a sample of the source, which is more important.
