Stabilization of complicated dolly move

[Tero Ahlfors]

It’s a private video so I can’t view it. Have you tried stabilizing it in smaller parts?

[David Beard]

My apologies. I changed it so it is now password accessible. Password is traced.

So what exactly do you want to stabilize? The only thing I’d stabilize is the dolly moves at the end of the clip and I got it pretty smooth with Warp Stabilizer set to stabilize position.

I would like to stablize the vertical bumps in the dolly move.

I agree with Dave. Not a great candidate for auto stabilization because the largest object in the frame is moving counter to the camera. Since Warp Stabilzer is a pixel effect, even if you tracked a version where you mask out the guy, you may not be able to apply it to the original footage.

With that said, it may be worth masking out the guy and trying a 3d camera track. I recall something like making the footage a 3d layer then using expressions to invert the 3d camera’s movement, and you can use the keyframes to ease motion (like your normal operator’s moves) back into the shot.

The Warp Stabilizer may help in another of the transformation modes.

If that fails then you can try and use a camera tracker to stabilize the shot. This requires a good camera solve though.

Once you have the solve you’d duplicate the solved camera, make the footage a 3D layer, parent it to the lower of the solved cameras and apply a smooth() expression to all of the top solved camera’s transform properties (position, rotation, etc.).

To keep the footage from ever leaving the frame you’d also need to either scale up the footage layer a bit or zoom in on the top (active) camera.

you can precomp it, add timewarp 50%, the timestretch the precomp 50%. This smooths out the bumps. I tested your clip and got good results.

Also, virtualdub’s deshaker works on dolly moves and it’s free!
Stabilizes horizontal/vertical panning, rotation and zooming.

another option is syntheyes that supports 3d keystoning correction while stabilizing.
