Deoldify Vapoursynth filter

[Dan64]

Deoldify: Preset Custom: Deoldify only, DDcolor or Simple working, but once enable DeepEx HAVC the preview just comes white color blank screen
Deoldify:  Preset Slow, Medium, Fast etc also working, but with DeepEx enabled HAVC the preview does work, but the image looks like a light sepia black and white with very faint color.

The DeepEx to work need the reference images, when you enable DeepEx you need to change also the value of SC thresh to 0.10 otherwise  the reference frames will not be generated.
The SC thresh don't have to be set only in the case has been selected "external RF", but in this case the reference frames need to be provided externally.
I don't know if Selur can do something in the GUI to enforce this behavior.
