Hi!

I wanted to rip a tv serie, which has problems due to bad conversion NTSC -> PAL.
I tested some adjustments (Telecide, interlaced, "blended fields") but i was not successful

Video characteristics:
PAL
25fps
Interlaced
and one defect: “blended fields”

Exemples Yatta help (fellow creature to the problem of the video)

Out:
http://img188.echo.cx/img188/6721/yattaexempleinterlacedok5es.jpg

Here are some seconds of captured video
video source:
Codec config: PicVideo (http://www.jpg.com) MJPEG 3 (quality 19), Subsampling : 4:2:2
PAL
720x576
25.000 fps (variavel as capture)

Download Capture file(40mb): http://s50.yousendit.com/d.aspx?id=1PISRJYN8GC7F222ZU13WVYD6R
Attention the file will be available for 6 days

I use filters in AVISynth 2.55.
I need help to correct the problems of the video source.

See a thread named "Restore24 revisited" by scharfis_brain. You can find it by using the search.

Btw, wrong forum;)

You could try this script

avisource("")
assumetff() #or bff()
bob() #or use dgbob()
selectevery(2,1) #or selectevery(2,0)

This is only useful if the blended field are mostly on either the top/bottom field. I use this script for CH4's "The Simpsons" and is much faster then restore24

Edit: I've just tried Fdecimate with rather good results.

@vtcosta:

I'm testing a
blend removal filter (http://forum.doom9.org/showthread.php?s=&threadid=94091) in the Development forum; would you mind if I used your MJPEG clip for a test case?

no, you're free to use my MJPEG clip for testing and if you could fix the "field blended" issue I'd be glad. not even if we have to convert to 24 fps or 29 fps and the for 25 fps.

With those configurations, I'll also need to fix the audio to synchronize with the fps, won't I?
