Deoldify Vapoursynth filter

[Dan64]

RF is the acronym of "reference frames" and yes it is equivalent to "exemplar frames".
I used this term because it is the term used in "Deep-Exemplar-based Video Colorization" 

You should rename the checkbox "DeOldify" at the left of "Coloring" panel in "HAVC" for the reasons already explained (the frame with the DeOldify parameter don't have to be renamed, it's Ok).

I suggest to move the "GPU ID" below Merge weight, so you have more space for DeepEx.

Having more space for DeepEx, you can create a dedicated "DeepEx" frame like "DeOldify" and "DDColor"

In this new frame you can add all the DeepEx parameters, including: method, render_speed, render_vivid, enable_resize, sc_framedir, only_ref_frames, dark, dark_p, smooth, smooth_p, colormap.

As you can note I added in DeepEx some of stabilization parameters, the reason is that when are used inside DeepEx these filters will be applied only on the reference frames and so are much faster.

If it is a problem the proper management of sc_framedir you can limit its usage by forcing the following convention:

if only_ref_frames is true
  sc_framedir = clip dir + "\RF_out"
if only_ref_frames is false and method > 0
  sc_framedir = clip dir + "\RF_in"

Once you have created this dedicated settings frame for "DeepEx" you can add also 'DeepExMethod', 'ScFrameDir' in the Preset section.

I know that this will complicate the GUI, take all the time you need, there's no rush.

Thanks,
Dan
