BM6K Pro Gyro Drifts In Resolve Stabilization

From the time I got my BMPCC6KPRO, when using Camera Gyro stabilization in Resolve, the image drifts up and to the right for the first 4 seconds on EVERY clip. I tried calibrating the gyro with no success. I didn't realize this until I purchased a 100-300mm zoom lens, and the effect is much more pronounced.

This happens even if the camera is sitting still on a solid surface. But then I realized that it doesn't just happen at the beginning of the clip. If I split a clip in the middle and then do a gyro stabilization in Resolve, the drift will occur from the split point in the clip, drifting up and to the right from that point for about 4 seconds. That leads me to believe it's a Resolve issue, not with the gyro data. It's very strange, and it makes the gyro stabilization unusable with longer focal lengths because it crops in too much and the drift is very pronounced.

Does anyone else see this? There is a post in the Cinematography section that indicates a similar problem for a user, but they have more of a rotation issue than a drift.

On mine, the drift is always pretty much straight up for 4 seconds - exact same length of time on every clip. And then there is a slow drift to the right for a couple of seconds. It follows the exact same path every time.

Which specific version of Resolve and OS are you using?

Mac OS, M1 MacBook Pro

This was happening in Resolve 18 Studio. I upgraded to 18.5 Public Beta 3 today and the issue remains the same.

You can see what happens here. Unstabilized raw footage followed by stabilization applied.

I'm the user in the Cinematography forum and its very similar to what I experience, a drift in one direction from the starting point of the stabilization for aprox. the same duration as the OP and also looks very similar to the video he posted.

If I skip to some other part that is nice and steady, remove the stabilization and use this as a new starting point it drifts the same way.

The video above shows how it behaves on my system. I've also exaggerated the scrubbing part in the edit tab to portray the issue more clearly. Trimmed the clip and re-applied gyro.

Forgot to post specs:

Windows 10 22H2
Resolve 18.0.3 (cannot upgrade due to Black Sun Highlight Recovery).

Bump!

Thanks for confirming I'm not crazy. So this doesn't appear to be a camera hardware issue. It suggests there is a bug in the Resolve stabilization processing.

Same effect for me using 6K G2.

There is another bug that I don't think it has been fixed and cannot check until I update to the new versions.

75fps gyro clips from the Pocket4K stutter like crazy.
And it has been confirmed by Captain Hook (BMD employee) in the Cinematography forum.

Which means, this is a possibility its Resolve related and not camera related.

This reminds me to mention something. The same stabilization drift issue happens for me with clips from my BMPCC6KPro at all frame rates and all resolutions. It happens with all lenses (with more pronounced effect on longer lenses). Gotta be a Resolve bug.

The drift happens everywhere. The violent shake only with clips over 60fps.

Just a follow up... Blackmagic has acknowledged that this is a Resolve bug. They were able to duplicate the issue using their cameras. Now I guess we are just waiting on a bug fix in a future update.

It's refreshing to have a bug report acknowledged and customer support to follow up in the manner they did.

Until then, use Gyroflow.

Cool. Looking forward to use it when its fixed.

Great! I've seen drifts myself. It drifts for a second or two until it settles. My workaround has been to extend the clip two sec before I actually want to cut. Gyro stabilize, then after cut away those two sec once stabilization is done.

This really doesn't work for long focal lengths because the stabilization crops in way too far. But it can work on some clips.
