Remove halos in AviSynth/Virtual Dub

[Dr.Who]

Any help with this? (around the microphone stand, for example).

That's ghosting, not halos. DeHalo filters won't work. GhostBuster() might help.

I've never used them but there's ghostbuster and exorcist for VirtualDub. If you can find them.

Exorcist is not enough and I don't really understand how to use Ghostbuster. After I use exorcist there are some black lines near the mic stand which I think they are halos.

I tried using DeHalo_Alpha for AviSynth. But I'm not getting away from those marks. Any suggestions?

DeHalo filters won't work since you don't have halos (over sharpening overshoots), you have ghosts (lower brightness copies of the original source overlaid slightly to the right). You can use Overlay() in subtract mode to reduce those. For example, this will reduce one of them:

Overlay(last, last.ColorYUV(gain_y=-245, cont_u=-245, cont_v=-245), 10, 0, mode="subtract") # remove the middle ghost
ColorYUV(gain_y=10, cont_u=10, cont_v=10) # restore lost brightness and color

But I see at least three ghosts. So you'll have to repeat that with different values to remove the other two.

Thanks for that! I have to figure out how to use it now, lol.
