View Full Version : What filter for Gamma correction?

I have FrameServed w/Tmpg (which allows Gamma correction), AviSynth (if there is a Gamma correction filter...where is it?) and Assorted VirtualDub filters (same as with AviSynth).

Tmpg is a good Frameserver, though the luma tends to be a bit higher than AviSynth and not quite as sharp. AviSynth has more options, represents the chroma and luma accurately enough but no gamma correction.

One more thing, is there a tutorial on how to use VirtualDub filters directly in AviSynth?

Try levels, uses the same settings as the Vdub filter for convience.

Levels
Levels(input_low,gamma,input_high,output_low,output_high,clip)

checkout the avisynth language reference for more info on this and other commands. http://www.math.berkeley.edu/~benrg/avisynth-reference.html#Levels
