Free Xiaomi 17 Ultra LUT (Mi-Log to Rec.709)
Turns the Xiaomi 17 Ultra's Mi-Log / Rec.2020 footage into normal-looking Rec.709 video. One .cube LUT, free for any project, no email.
The zip holds the same LUT twice: a 65-point file for editing, and a 33-point file for monitoring on a camera or in an app, or for older apps that won't load the larger one.
Built from Xiaomi's published spec and checked against Xiaomi's own LUT.
