Deoldify Vapoursynth filter

[Dan64]

Let me try asking this in a different way.  With DeepEx enabled.  DDcolor only.  SC thresh set at 0.10, SC min freq at 0 (disabled). Method HAVC (not using reference frames).
 
1. Lets say Scene Change is detected at Frame 100 and the next Scene Change detected at frame 200. Will the coloring of frame 100 thru 199 be based on Frame 100?  
2. Lets say SC min freq is set to 50.  Will the coloring of Frame 100 to 149 be based on Frame 100 and 150-199 be based on frame 150?

Answer:

1) Yes
2) It will be generated the following additional reference frames: 50, 150

I suspect that the the scene threshold starts very late, so the beginning frames don't get colorized. 

Dan64, what do you think I'm doing wrong, what settings would you have used for this?  I figure best way to learn is thru example.
Is this a case where reference frames are needed to be created?

TestExamples

Your example is very difficult to colorize, your guess that the reference frames are generated too late is correct.

If you need to verify the generated reference frames you can used the following settings (threshold lowered to 0.02):



there "ref_out" is the directory that will be used to export the reference frames. The generated video is not usable, this settings is useful only to extract the reference frames. Feel free to stop the encoding when will be generated enough reference frames.

With these settings you should find the frame: ref_000065.png



Copy this frame in another directory, for example "ref_int" and rename the file in: ref_000001.png

Now you can encode the movie using the following settings (threshold increased to 0.03):



In this way the file ref_000001.png will be added as reference frame n.1 and DeepEx will be able to start to colorize the next frames.
