    Hello,

    I do have (MPEG2, 50 mbit PAL) captures from digital betacam which were copied from an analogue source (umatic) with the wrong chroma phase.
    Now i have a lot of chroma lines accross my picture.

    Is there any software that can correct this?

    (Sorry, this maybe belongs in the restoration section.. i posted it wrong)

    AviSynth:

    Code:
    WhateverSource()
SeparateFields()
MergeChroma(last, Blur(0.0,1.0).Sharpen(0.0,0.7))
Weave()
# any other filtering...
    By the way, they're called Hanover bars. https://en.wikipedia.org/wiki/Hanover_bars

    Oh, and the above process needs to be performed at the capture frame size, 720x576, before any resizing.
