Xiaomi 17 Ultra VS 15 Ultra — I Shot 4TB of RAW Video to Find the Surprising Truth!

After shooting over 4 terabytes of RAW video on both the Xiaomi 17 Ultra and Xiaomi 15 Ultra, I discovered something I genuinely didn’t expect… For pro video and filmmaking, the new Xiaomi 17 Ultra isn’t the clear upgrade everyone assumes. In fact, in several critical areas, it may actually be a downgrade from last year’s 15 Ultra — at least straight out of the native camera app. But the story doesn’t end there. I found three incredible pro video related features on the Xiaomi 17 Ultra that are truly game changing for pro video in 2026. When you bypass Xiaomi’s heavy image processing and unlock the true sensor performance using ‪@MotionCam‬ Pro RAW video, the 17 Ultra suddenly becomes one of the most powerful pocket cinema cameras of 2026 — with massive gains in sustained recording performance, Direct Log capture, and future-ready codec potential. In this deep technical test, you’ll see: • Real-world RAW video comparisons between Xiaomi 17 Ultra and 15 Ultra • Native camera image quality, bitrate, color science, stabilization, and Log performance • The truth about DCG, LOFIC, Xiaomi Log, and ISP processing • Long-duration thermal and recording performance in MotionCam Pro • Whether the 17 Ultra is truly one of the best Android phone for filmmakers • And the bigger question: Has Xiaomi quietly abandoned pro video? RAW test clips are available for channel members if you want to inspect the footage yourself. ⚙️ RECOMMENDED GEAR & Xiaomi Log LUT download: 📌 Get EPIC LUTs for Apple Log & Samsung Log: https://epictutorials.com/collections... 🚀 Save 10% of Thermal Master cameras with code ''THERMALBF' at https://tidd.ly/3Miarjy 🎨 Get MotionCam Pro for Android & unlock true RAW video: https://play.google.com/store/apps/de... 💥 Download official Xiaomi Log LUT, DCTL, white-paper: https://drive.google.com/drive/folder...
