iPhone 15 Pro Max ProRes HD 60fps broken on iPhone 15 Pro Max

I've been trying to play around with ProRes today, and I discovered that ProRes HD 60fps seems to be "broken" on my iPhone 15 Pro Max (running iOS 17.1.1). It only shows a blurred picture of what the camera was previously showing in another video mode.

If I change it to ProRes 4K 30fps, or HD 30fps, it works. It doesn't matter if it's HDR, SDR or Log. Regular (non-ProRes) video modes work. I already tried to reboot, of course, and I even tried attaching external storage: no difference. Using the front camera it also works.

I don't remember if this worked on an earlier iOS version or not, as I don't really need ProRes. So I'm not sure I wanna go through the trouble of restoring the iPhone to see if that fixes it. It's still annoying to know it doesn't work.

Does anyone else have this issue?

Thank you for trying it out. That's so weird.

I did some more tests: if I toggle "action mode" on, it works. As soon as I turn it off, it doesn't work anymore. I really wonder what's up with that...

I found the issue: if under Settings -> Camera -> Record Video I set "Enhanced stabilization" to On, it works. If I turn it Off, it doesn't work anymore.

Yep! You sir have seemingly found a bug I think, lol.
Seeing the same behaviour when turning off Enhance Stabilisation…
