Installation
To configure gamma conversions, select the video final gamma in the gamma
out option, and activate the gamma conversion.
The gamma conversion can be fine tuned with the highlights, midtones,
shadows and exposure correction filters.
When converting to or from Rec.709 gamma, some conversions may render
upper levels out of range, this is mathematically correct, but the video may be
improved by keeping these levels, in this case you can select Rec.709
Tonemapped instead of Rec.709.
