    Here is a sample https://www.sendspace.com/file/1bdci9

    I've run just straight Gradfun3() and it reduces it a decent bit, but wondering if there is anything else that can kill it even more.

    Re-using the filter is not illegal.

    For e.g. Sharpening the image with the Sharpen() filter with 2.0 as param, trick is that the highest value is 1.0 so..

    V=source..

    V=Sharpen(V, 1.0)

    V=Sharpen(V, 1.0)

    V

    The same goes with any [Video/Audio] filter.

  3. To keep banding from coming back you need to encode with sufficient bitrate and/or with a 10 bit codec.

  4. I prefer f3kdb (https://f3kdb.readthedocs.org/en/latest/) over gradfun3 + jagabo is right debanding in Avisynth is one step to keep the dithering a higher bitrate or 10bit encoding is needed.
    Also, most Avisynth filters have parameters which allow to lower or increase the effect of the filter.

    Last I recall, gradfun2dbmod was a pretty good dithering filter for removing banding.
