Converting from ProRes to DXV3 Causes Red Saturation Levels and Darkening Blacks

[RedGoAway]

Hello,

I've been asked to supply a file in the DXV3 format for a conference abroad. I'm converting a ProRes file to DXV3, however, the resulting image is really red and the black levels are being crushed, so details in the black areas are non-existent, despite the video scopes showing the blacks to be at zero.

I am using "Alley" to convert the file.

Does anyone have any idea what is going on?

Thank you very much for your help!

Can you share the prores file?
