Neat Video changes color in Adobe Premiere Pro CC 2019
H. Why does plugin Neat video change the color of the video clip? A purple color appears. This happens on video from the drone, which were filmed in the d-log and then DLog-M + to + Rec709 was applied to them, which was provided by the Dji off site. I contacted representatives of the company that produces this plugin, sent them a test file, described the problem and received an answer from them today.
Thank you for the test project and footage. We have checked the project and found that
the problem originates in Premiere itself. Here is how you can check that:
1. Set Mercury Engine to Software only in Preferences of Premiere;
2. Set Sequence Settings->Maximum Bit Depth, Maximum Render Quality;
3. Add Posterize Time (Premiere effect) to that clip in your project (do not add Neat Video).
Now try to enable/disable the Posterize Time effect and observe the colors changing the same way
they did when you added Neat Video.
You can see the same problem when Mercury Engine is set to use CUDA. But in this case
you need to add Posterize Time before/above Lumetri.
If you compare the Software only vs CUDA modes of Premiere's Mercury Engine, then
you can also notice that the decoding quality (the way Premiere reads the input video file)
is worse in the software mode as well.
Both issues seem to be caused by problems in Premiere itself, probably due to bugs.
A possible workaround would be to render out the color corrections to an intermediate video clip
and then use that clip in a new project where the noise reduction would be applied.
Another option is to contact Adobe and ask them to fix those problems of Premiere.
That could work but would take a lot of time.

I checked and really, after applying the effect of Posterize Time, the same problem occurs.
even use only the Lumetri panel, without using the drone’s lut DLog-M+to+Rec709, the problem with the purple color continues to be present.

I'm having the same issue. Seems to be an Adobe Premiere Pro problem. Please fix it!

Still no fix here?! Had the same issues with Neat Video..
Now a few weeks later I have a similiar issue with Premiere without any Plugins. I have a dynamic link AE File. Rec709/16bit color in After Effects.
Now: The Footage shows this magenta color shift again in Premiere. But only with Mercury Engine CUDA enabled. If Software only the colors from the dynamic link File are the same as the original Footage. Both Clips have exactly the same lumetri settings of course!

I'm getting exactly the same issue. The only way Ive found to resolve it is to color correct towards green/yellow, not ideal!

Well it seems like even after 6 months Adobe hasn't fixed the problem because I'm running into the same issues right now...
Alexey have you found a solution for this or how did you proceed?
Best regards Dido
I also found out that if you turn off the CUDA, then digital and violet noise also appears on the video, even if you do not use noise.
