How to scale tracking import. Help Please!

Hi good day. I am new to this great forum and blender community.

I have several days looking for how to solve this problem.

I am looking for a hero to help me:

I have imported a tracking into blender from Boujou.

When imported, the tracking looks this size:

It looks very small, and when trying to add 3D objects it is somewhat complicated.

I would like to know:

How do I get to normal size?

Beforehand thank you very much.

Add a empty to the center of the grid. Parent the Camera and the tracking markers to the empty and scale the empty and see if that works.
