It can work, but I would not apply strong stabilization twice by default. HyperSmooth has already cropped/warped the image to remove motion. A second aggressive pass may crop more, amplify edge warping or create that “floating” look.

For residual movement, use the lightest post correction that solves the specific problem.

Also distinguish shake from intentional motion. On helmet and handlebar footage, some movement tells the viewer what the bike is doing. If you flatten everything completely, the video can feel detached from the ride.

I stabilize shots that are hard to watch, not every clip just because the button exists.

That is a good use case for VSDC's stabilization tool: as a selective cleanup pass, not an automatic second HyperSmooth. I would test a short section and compare crop, edge distortion and horizon behavior at 100% view.

If the problem is mostly a slowly tilting horizon rather than high-frequency shake, a manual rotation/keyframe correction can sometimes preserve more of the frame than another full stabilization pass.

Manual correction was actually better on two of the problem clips. The image itself was stable; the camera mount had slowly rotated a few degrees during the ride.

I had been asking stabilization to solve the wrong problem.
