So, I'm going to plan on taking media in the next year of college and a youtuber. I currently am trying to figure out how to follow something in a video using the motion tracker. If you want to see an example of what I'm trying to achieve here it is.

As you can see I'm trying to track the person but its a little wonky - using motion tracking can help by copying the keyframes over to pan/crop so it can track the person easier zoomed in - is anyone able to help me with this?
