Color change on encoding

[Lipomo]

Hi

First, I'm using the experimental version 2024-11-05. When I encode my FFV1 video, color matrix BT 709 (which seems to be detected by Hybrid), the resulting encodings have different colors, as if it was converted from BT 601 to BT 709.

Here is the video sample : Google drive

And when I close Hybrid I have this message :

<HybridData name="defaultContainer" value="mkv"/>
and
<HybridData name="defaultContainer" value="mp4"/>
differ.

<HybridData name="mkvColorMatrix" value="BT709"/>
and
<HybridData name="mkvColorMatrix" value="GBR"/>
differ.

<HybridData name="mkvColorRange" value="Broadcast Range"/>
and
<HybridData name="mkvColorRange" value="Unspecified"/>
differ.

<HybridData name="mkvColorTransferCharacteristics" value="Unspecified"/>
and
<HybridData name="mkvColorTransferCharacteristics" value="Reserved"/>
differ.

<HybridData name="mkvColourPrimaries" value="Unspecified"/>
and
<HybridData name="mkvColourPrimaries" value="Reserved"/>
differ.

<HybridData name="mkvMaxContentLight"/>
and
<HybridData name="mkvMaxContentLight" value="1000"/>
differ.

<HybridData name="mkvMaxLuminance" value="0"/>
and
<HybridData name="mkvMaxLuminance" value="1000"/>
differ.

<HybridData name="mkvMinLuminance" value="0"/>
and
<HybridData name="mkvMinLuminance" value="1e-04"/>
differ.

Note that i have reinstalled Hybrid from scratch.
