Picture is too dark, how to lighten up?

[JaLe]

I have installed latest GordianKnot 0.28.1

Original DVD's picture is little too dark and I want to lighten it some.

If I adjust Gain & Offset with DVD2AVI's luminance filter and then open that d2v file with GordiaKnot picture is just how I adjusted it. Now I make crop, resize, e.g. and save avs file.
When I open this avs file with VirtualDubMod picture is again too dark.

So, how I can make it ???

Do I need to do it with some AviSynth filter or VirtualDub filter or what?

Maybe the luminance-information in the d2v-file isn't regarded by avisynth?
You can use several avisynth-filters, for example "Tweak(Bright=anyvalueupto255)" or "LumaFilter(+10,1.1)" and some others...
The LumaFilter value is the one suggested in the readme of mpeg2dec3.dll, have to do some research how the parameters work, but tweak should do exactly what you want...

Oh, and welcome to the forum :D

No, mpeg2dec doesn't read these parameters, neither does it care about crop or resize. I'd use Tweak in a situation like this.

Thanks :cool:

LumaFilter does the job. I have to try Tweak also.
