tracking text with multiple tracking points?

Hello i am having issues using the tracker in fusion to track title text to sit on the screen.
what is happening is when i use either the "planar tracker" or "tracker" the text or image that I attach the track has a slight or even severe "wobble" to it. its not smooth.
what i think would help would be to add multiple tracking points, which when i do in the "tracker" it still doesn't work and the text just moves around the screen more.

any help getting smooth tracking without wobbling or more important adding multiple tracking points??

It is hard to be certain from the screenshot, but there should be two boxes around the point (the outer one might only be visible when pointing at it with the mouse): the smaller one shows the part of the image being tracked, and the outer one is the search area in which Fusion will try to find a copy of that image as it was in the prior frame, to try to move it. If there are other "matches" to the tracked area within the search box the tracker could be getting confused, so try to ensure the area being tracked is both high-contrast and sufficiently distinct from anything around it.

Having multiple trackers on different planes of the footage will usually give poor results.
Your tracker 4 is on the back plane, tracker 3 is on the front plane.
Also, you might try first stabilizing the footage.
Also, I see you have a planar tracker in there.
It can often give smoother results than a basic tracker.
Try using that (another planar transform), or a new planar tracker in the same plane where you want the text.
