BD Rebuilder: how to handle grain, insert filter?

[Hobojobo]

I am trying to backup some older movies: Amercican Werewolf etc, Firefly,the TV series (not old, but...)
How can I reduce the grain using BD Rebuilder.
Is there a way to tell BD Rebuilder to handle this.
Or let BD_RB me use my own script?

If that is the case, how should it look like?
Any suggestions?

You can insert your own avisynth filters in BD-RB:
Menu Settings => Setup => Tick 'Use AVS filters during encoding'
A window opens where you can put in your avisynth filter script.

Thank you, Sharc.
I overlooked that line in the setup.

I'm not into avisynth-scripting:

What would be a script to recduce light noise?
(Nothing to do with BD-RB, i know) :rolleyes:

Have a look at this function, is very very comprehensive and has plenty of options to fiddle with but has some very good defaults to make life easier

Basically it analyses the noise present and tries to remove just the noise, weather its to much grain or other noise by scanning a couple of frames and working out the difference and removing just that

Be warmed though that is is very complex so very slow as it calls a lot of filters to do the job, to the people that use these filters ir write them time is not really an issue, but the final output is

I have used these type of filters/functions before and anything better than 5-6FPs is good, some of the really complex functions that calls other functions and filters can struggle to manage 1-2FPS but the final output video is vastly differemt to the source. So much so that it might as well be a new video

Thank you for your link.What a powerful script.:confused:
It is a bit too much to begin with.

I thought of:

mergechroma(blur(x))

or similar.
