match moving

Hi everyone,I’m doing a research for a project to improve the way to do a match moving (until now, it’s just an idea), but I don’t have information about an specific topic, maybe one of you can help me. I need to know how exactly works the data of a matchmoving software.

When you have a file matchmoving file how it’s formatting?
I imagine it has position and rotation information in XYZ axis, but I’m not sure how exactly
I’m looking for any kind of information.

thanks in advance
