Alter update rate for streaming GCS position

Hi all, hoping someone can point me in the right direction.

I’ve been trying to use Follow Mode with the Set ROI option to control my gimbal, but am finding it very “jumpy”. It appears from the log that the GCS position is only updated every second, which I’m relatively sure is why the video looks a bit stuttery.

I’m using QGC running on a Herelink v1.0 with a Cube Orange and Arducopter 4.5.7. I’ve dug through as many menus as I can find, and some config files too, with no luck on that.

If anyone can suggest a way to alter the update rate, or any other suggestions that would be brilliant?

AFAIK mobile GNSS receivers tend to work at 1Hz. There is some work on kinematic shaping for follow mode that sounds like it should help with that though I don’t know the details.
