In the distance, people or pieces of structures in black and white

[Roy-Bertoli]

Hi Dan, I noticed that in all the films, whether using longcat-gguf or gguf-qwen, it always leaves some people or pieces of structures in black and white, especially in the distance. I don't know if it's possible to improve it. I thought it would be useful to point it out to improve this fantastic program. I'm including some photos from the last film that I colored with longcat-gguf, but these problems, as I said earlier, occur in all the films.

When using LongCat you must use 8 steps as shown in the images below

I attached my tests and LongCat images colorized with 8 steps for me are well colored. Only for qwen GGUF q4 I added the colorization with steps: 2, 4, 8. As you can see above 2 steps gguf-qwen-q4 introduces artifacts and with 2 steps the colorized images are not so good as the ones colorized with LongCat.

In the archive below you can find my results.

sorry, but I explained myself badly, LongCat colors the reference images well, unlike qwen gguf which leaves images in black and white, but the photos I posted are taken from the film colored with comnet2 not in the reference images which are all in color, when I color the film with comnet2 it happens sometimes that in the distance people or faces or things are not colored.

It is not really a CMNET2 problem (or at least not this kind of problem).
You can test yourself by using "Fix Colors" as shown in the image below

As you will see the image colored using CMNET2 is well colered (no B&W subjects). Maybe the problem is the low resolution of the frames used when the clip is colorized.

As a test, you can try to recolor only a small part of the clip including the frames not well colorized, using the render speed slow or slower as shown in the example below

so when i color the whole movie with comnet2 i have to change the render from auto to medium or slow, what do you recommend?

First try the test that I proposed in my previous post. If the problem is related to resolution you need to find the render speed that satisfies you. It always a compromise between render speed and quality.
