ToneMap settings greyed out, encoding with ToneMap enabled fails

[Selur]

Now the Vapoursynth tab appears, but is greyed out.

If you want to use Vapoursynth you need to set Filtering->Support (lower right corner) to 'Vapoursynth'.
For Hybrid to work properly with Vapoursynth you need the plugins listed here:
https://github.com/Selur/hybrid-vapoursy...ld-plugins
and vsViewer.

The Tonemap option now works fine though, settings are not greyed out anymore.

Okay.
