Gamma (colors / contrast) too dark

[Kattekrab]

I play World of Tanks and I post my best replays on Youtube.

At the moment I use Fraps.  But I notice it puts a load on my system with stuttering gameplay and frame drops as a result.  That's why I want to try Dxtory.  It feels much more light weighted then Fraps, which is good.

But the colors or gamma is much darker then Fraps.

Both youtube movies are encoded with Handbrake with the same settings.  I tried Dxtory with it's default codec, Lagarith and MagicYUV and all the AVI's before encoding are dark.  So I think it's Dxtory and not the codec.

Is there something I can do to brighten the video's?  Handbrake doesn't support gamma adjustments.  Youtube has a filter to brighten the video, but probably with a quality loss.

Thanks for any advice!

It is specification.

Thanks for the feedback!
So this means that everybody who uses Dxtory and records World of Tanks has the same dark video?  You can't solve it by using another codec?
