Deoldify Vapoursynth filter

[Dan64]

I made some test with Around The World in 1896.

By using the "Darkness" filter with an extended range, it is possible to obtain an effect similar to "Lost in Time".
If you increase the range of dark/white to 0.4/0.8 you are able to change almost all the image because this range cover most of the luma in bright scenes.
Then by increasing the "darkness" to 0.6 it is possible to reduce the "vibrancy" of the colors (thanks to new method used for it).
The gradient mask will apply this effect gradually with the luma, obtaining an interesting effect.

In my opinion the image obtained with DDeoldify is even better.

I think that we are almost done, with this filter.
