Deoldify Vapoursynth filter

Nice. What to DeOldify and ddColor on their own look for this?
Used this clip from https://www.pexels.com/search/videos/flowers/.
=> for serious coloring, one probably should still stick with settings different value per scene (especially when the content type changes,..) or if possible provide deepEx with enough reference frames.

Cu Selur

For serious coloring the best approach is the following.

1) Start with a simple

clip = HAVC_main(clip=clip)

If one is happy with results the next steps are not necessary. 
If there are some scenes with the wrong colors it is possible to adjust them following these steps:

2) Switch to "custom" mode, enable DeepEx, select method HAVC, set the "Ref FrameDir" and enable "Reference frames only",
    Then set "SC thresh = 0.1". This will output a non usable video, but will produce also in the selected directory the reference frames used by DeepEx.

3) If one is lucky the frames that need to be adjusted are already included in the directory specified previously. Otherwise is necessary to manually add new reference frames.

3) supposing that only the reference frames that need to be adjusted are: ref_000890.png and ref_0021450.png.
    These frames can be substitute with images containing the same elements and having the same size but with the correct colors.
    Then it is necessary to put the adjusted frames in another folder (with the same frame number), for example: "new_ref_frames" 

4) Select the method: "HAVC + RF same as video", and Ref merge = "med" and set the "Ref FrameDir" to "new_ref_frames"   
    In this way DeepEx will use the same frames as in the step 2, but the frames contained in  "Ref FrameDir" will override the frames produced by HAVC.
    The output of the movie produced in this way should contain the correct colors.
