Tracked background doesn't fit after rendering

So I tried my hand at motion tracking and ran into a weird issue. I tracked my footage, set up my scene and rendered it. When I went to overlay the footage with the render though the background doesn’t fit anymore.

This is how it looks in blender in rendered view

But this is the rendered result

When I take the render alone and try to overlay it over the original footage with Premiere Pro I get the same result.

I’m really clueless how to fix this. Any ideas?

I’m on Windows 10, issue persists across blender 2.90.1 and 2.82.

[Blend file ]if anyone is interested.(
