How are you using Hybrids Vapoursynth filters 
Are you using them blindly?
You should always check the effect of filters.
In the 'Filtering->Vapoursynth', in the right lower corner, is the normal Vapoursynth Preview button, if you press it Hybrid will open a vsViewer Window which will show what the current Vapoursynth filter settings will do.
If you enable 'Compare View' and press the Vapoursynth Preview icon, the vsViewer Window will show the input and output of the filtering.'
If you enable 'Synth auto refresh' each change will cause the Preview to refresh. (read the tool tips)
You can also enhance/adjust the Preview by using the settings under Filtering->Vapoursynth->Misc->Preview (I especially recommend checking the 'Split Compare View' options, when using 'Compare view'.)
If that Preview does not work, properly, neither will the encoding.

Ps.: If you see a button, check the tool-tip info. Especially at the beginning, you should play around with settings and read the tool-tips.
