You're taking a relatively decent number of frames, but could be running them at a higher frames-per-second to make the final shots less juddery. There was some set bump/camera shake too - maybe tape/tack your set down if you aren't already doing so, and try not to nudge your camera when filming. A tripod really helps with that. Hope this helps!

Please do not post your film twice. I've merged this with the original post.

As for advice, jampot summed it up pretty well. A higher framerate and a camera that moves a bit less would be a good start.

Nice use of the edge of frame to create the illusion of Magneto lifting the car!
