  1. How do I reduce / remove them? This type of artifact is common in old concert videos as far as I know.

    I tried WDeflicker and it would be a good way to at least reduce them a bit but it introduces dark lines just as Osmiridium warned - "If your values are too strong dark horizontal lines may appear in scenes with high contrast." Perhaps there is another way which I just can't think of? Thanks very much in advance to whoever replies!

  2. Try to use some processing in frequency domain - this interferer looks like perfect candidate for such approach.

    Looks like the lights are the cause of the lines.

  4. Looks like poor deinterlacing, or leftover combing artifacts.

    If you have already deinterlaced this, then try this. It usually helps with that for me.

  6. This is regular chroma interferer - perhaps camera was placed badly or some cable issue... filtering selectively this frequency in vertical direction should deliver clean picture...
