My Lumetri Presets suddenly stopped working and decolourised everything!

Report · Nov 25, 2025

Hi there,

Apologies if this is a repeat post but I have a couple of conditions and really struggle with information sometimes.

I have gone back into a program file I did in 2024 as I wanted to make some changes. Unfortunately, the Lumetri Presets that I used have stopped working and turned everything grey!

I don't know if an update knocked everything out? Can anyone help? I was using "Canon C500 Clean Punch NDR", I made some changes to my liking and then - it's just stopped working. I'm trying to avoid having to spend time doing colour grading again!

Can anyone help? (Please explain as if you're speaking to an old granpa cos honestly, that's not far from the truth...)

I can't tell if you're working in the earlier or current version ... details need to be very precise.

And the massive changes made in the color management options for the 25.x series builds unfortunately means that pre-25.x projects do need to be redone for color.

But that's actually pretty easy, typically it just means setting up the new color management panel for that clip and sequence to accomplish what happened before.

Post full details and I can help.
