Hi Enrico,
Thanks for reaching out!
I understand you're running into an issue when trying to adjust the brightness and contrast of a video. Can you please elaborate on what you mean by the function not working correctly? I also want to point out that the changes will be visible immediately on the video stage, but you won’t see the changes if you preview the video until you click Save & Close.
If you can provide a screen recording of what you're seeing, or share your file with us, that would be greatly appreciated to help us troubleshoot! You can upload it here or privately in a support case, and we'll delete it from our systems once troubleshooting is complete.
