I wonder how this compares to purely vision-based systems which use nothing but the images themselves for stabilization. Here are some quite old results of stabilization using image-based 3d-reconstruction of the scene which I wrote more than 10years ago, compared with other stabilization programs of that time (Deshaker, Adobe After Effects, Youtube). With todays improved hardware and progress in 3d-algorithms you may not need any additional gyroscopic data.

So So useful <3 Stabilization = you have to zoom-in, loss of FOV. Depending on Action Cam and undistortion parameters, this can be different, sometimes too little, sometimes too much. Gyroflow allows you to dial it in. Lot's Stabilization in a particularly shaky spot and widest FOV everywhere else, smoothed between to be unnoticeable.

As a drone pilot I used this before davinci studio implemented something similar. I highly recommend.

How is this different from usual sensor stabilisation techniques? Is it because it can adjust for a wider range of motion?

I wanted to try this but sadly it seems my A7 iii doesn't record gyro data.

That this also helps so much with rolling shutter correction is wild! Epic.

Such a fine piece of software.
