Old VHS tapes often have horizontal lines/bands that slowly scroll up or down the video during playback. This video is already on DVD, so I am trying to remove the banding in post-processing.

The Tools I'm using include:
VirtualDub, AviSynth, Premiere Pro CC, Davinci Resolve.

Are there any techniques, plugins or scripts that can help remove this?

    Those are usually "hum bars" caused by the difference in rate between NTSC video vertical (59.97) and US AC power (60.0). It would be a great trick indeed to build a plugin to find and track those. I've never heard of such a thing and would be surprised to find one -- but I'm always being amazed by what people accomplish. Good luck

Neat Video has been working miracles on footage for us so far, you can give the trial a go! We've never tried it on this specific artifact (that I know of) but it does have features for restoration/archival type damage, and I highly recommend it.


If the video in question is in grayscale, you can always just remove the colour by reducing the colour saturation by 100%. You can do this in OBS by adding the Effect Filter "Color Correction" on the Video Capture Device.


Caused by not enough back pressure on the tape as it goes to the head try cleaning the head if that doesn't work the machine needs to be checked by a tech.
