Color change on encoding

[Lipomo]

So Hybrid guesses the color matrix based on the resolution.
You can set the color matrix value of the mkv container under "Config->MKV tagging->VUI->Matroska advanced video signaling".

Regarding color matrix info on media info, yes you're right, but that's just because I cut that sample with a software that removes them. I have the issue with the full video that have all matrix infos. 

Question : Since Hybrid guesses color matrix based on resolution, why did it changed colors since the video is 1920x1080 so BT.709 to BT.709 ?

And when I close Hybrid I have this message :
This happens if you tell Hybrid to:
a. overwrite the defaults on closing
b. report changes to the config
So, to me, it looks like you asked for this.

I checked all warnings, but I don't think I checked any option that overwrite settings. I always save them manually. 

Where is that option to save settings on close just to make sure it's disabled ?

Also, why does it say GBR while the source is BT.709 ? 


Here is the media info from the raw file :

Ps.: Depending on what filtering you applied, color changes can also happen due to filtering.

I though about that so I tried without any filtering and the issue remains.
