Implement encoding ideas in VirtualDub

[stormy1777]

Hi there,

I got a few suggestions from thread: https://forum.doom9.org/showthread.php?p=1861051

relating to reducing noise in mostly dark scene.. trying to figure how to exactly implement this in VirtualDub2:

Suggestions are:

1) 'crush the blacks' or 'denoise'; are there VirtualDub's built-ins/filters that can do that?

2) It was suggested the clip is probably 'full range' (I've no clue exactly what that means, it is taken using a DSLR, in color, without any further modifications) based on this in Media info:

Color: Full

How does one set the 'levels' on it?

3) How does one "set your psy:rd to 0.0:0.0"; found this x264 settings page:

http://www.chaneru.com/Roku/HLS/X264_Settings.htm#psy-rd

but no idea how to do that in VD2.. is that on the x264 "extra parameters" ?

a still image from the video for reference is:

the full context of suggestions is in original thread...

Thanks for any tips...

OK, for #3, indeed in Extra command line (Ctrl-P -> configure the x264 encoder), just added

--psy-rd 0.0:0.0

that seem to work and reduced the filesize significantly!!

Sorry, have no time right now to pick entire context, quick ideas:
1. crush black/manipulate levels: internal "levels" in rgb mode, or my "6-axis..", or some 3rd party filter (there are few notable, like "curves"). All in rgb mode.

2. How does one set the 'levels' on it?: normally you should do nothing special, but depends what you do. When you apply rgb filter, it will receive proper colors. One thing to remember is "levels" with option "do not work in rgb" will translate colors as if they are limited range (this destroys full range colors).

Ok, thanks Shekh ; original thread came back with specific avisynth code that helped resolve this.

Thanks for mentioning 'levels' & '6-axis color correction' internal filters by name - I will surly try these next time around...

Now I remember why I love working directly with VD's filters, b/c there's a direct PREVIEW that shows the effect on that frame right then and there :)

Thanks!!
