Media Encoder 25.1 colour is so broken! Blowing out the saturation/changing colour space!

[Desmond23864040y3ur]

Since updating, when I send an h.264 from Premiere to Media encoder it EXPLODES the colours. See reference pics. No idea why and I can't find anything that fixes it. Tried colour spaces, interpretation, all the normal stuff. it's just broken! Help??

Try turning off Hardware encoding in the Video tab of the export settings.

tried this and no beuno...

UPDATE: This is only happening to the footage filmed on my A7iv in Slog3Cine. I'm assuming it's an HLG issue or something similar but I can't find a toggle or check box that makes a difference. I've tested everything I can see, including in the media encoder settings.

SOLVED: I use the sony input lut instead of Adobe's native one. There is now a check box on the colour settings tool that says PRESERVE RGB. This needs to be checked if you're using this before sending anything to media encoder. Here's a screenshot, hope this helps anyone having the same issue!
