I have finally been able to take the gyro out for a test spin with our Pocket 4K (firmware 7.9.1) . Works quite well, except for one weird thing.
2 clips of the same tree in the forest taken from the same place at aprox. the same level of shakiness. Same settings: BRAW Q0, 18mm (Sigma 18-35), Shutter 45. One 60/25 4K DCI and the other 75/25 4K 2.40:1 cropped.
Metadata sees both as 18mm (which is the right focal length).
In resolve upon applying camera gyro stabilization: - the 4K DCI one is very smooth as expected - the 2.40:1 gets an incredible aggressive stutter (almost constant shake. like an error)
This shake also appears on all 2.40:1 clips I've taken that day (shutter between 30 and 45, various exposures) while all the 4K DCI 60fps clips work as intended.
Is this user error, Davinci Bug or Camera Bug? (does the gyro stabilization work in crop mode?).
I get similar results shooting BRAW 4096 x 1720 @ 75/25 fps HFR: Insanely, crazy shakey footage (clip moves left/right very fast) after Gyro stabilization applied using latest DRS 18 and Pocket 4K firmware. Also happens with BRAW 75/24 fps HFR clips.
The same BRAW clips with Perspective stabilization applied play smoothly, as expected.
Other BRAW 4096 x 1720 HFR clips, such as 60/24 and 60/25 play as expected with Gyro stabilization applied.
I tested with a Panasonic 25mm f1.7 lens, and an Olympus 12-40mm f2.8 at 40mm.

Could it be that not enough samples are written for higher frame rates? Interestingly, Sony‘s gyro stabilisation doesn’t work for 120 fps recordings at all. It might be interesting to do a test with Gyroflow.
Now that the cat #19 is out of the bag, test it as much as you can and use the subforum.
Studio 18.6.6, MacOS 13.6.6, 2017 iMac, 32 GB, Radeon Pro 580 MacBook M1 Pro, 16 GPU cores, 32 GB RAM and iPhone 15 Pro Speed Editor, UltraStudio Monitor 3G
Also found a weird bug (still on 18.0.3 because of the black sun fix that is needed).
Whenever I apply gyro stabilization the clips are smooth but they all start with a weird slight rotation to the left at the very beginning. If I then scroll to a portion that is smooth and straight (thinking its user error), trim the clip to this new starting point in the edit tab, clear the tracking and re-apply stabilization from this new starting point it introduces that weird ass rotation to the left to the trimmed clip as well.
Mine is doing a similar thing, but not rotation. It moves in the same direction on all clips for the first 4 seconds or so. I just posted another thread about this, but I am new here and it's under moderation.
Here is sample footage (before and after stabiliation):
Sorry for the cross-posti, but head over to the Resolve board if you are experiencing this. The issue points to a Resolve software issue, not a hardware problem with the camera gyro.
