I'm very new to blender and am currently having trouble with a motion tracking shot. I have tracked the camera of a scene, and placed a modelled gun onto a table. In Cycles and Eevee the tracking looks perfect and stable in the viewfinder, however, after rendering in Cycles (in EXR sequence) the movement is completely off. The gun moves in roughly the right direction but kind of floats around and makes some seemingly random movements that should not exist. Any help is appreciated!

I followed this tutorial: https://www.youtube.com/watch?v=ui0JUHE12k8&t=180s
