ToneMap settings greyed out, encoding with ToneMap enabled fails

[damian101]

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.

Setting Support to Vapoursynth did it 
Since Vapoursynth filters in Hybrid don't seem to get greyed out when not installed, it indeed seems to be a good idea to just install them all.
I assume vsViewer is needed for Filter view with Vapoursynth... Will try installing it sometime in the future.
