Tracker To Keep The Subject In The Center Of The Frame

Hello...
I have 4k footage that I crop in and focus on a subject as it moves.
My workflow is to zoom and position to frame and then keyframe all the subsequent zooms and positions.
I was thinking that it might be doable with a tracker.
The only issue is that the tracker usually keeps another object attached to the subject as it moves.
I kind of want to do the complete opposite.
Would this be possible?
Thanks...

You want to use a tracker to do the opposite of tracking? That makes no sense. If you explain what you're trying to do rather than what you're not trying to do, I think we may be inclined to offer suggestions.

Sounds like you want to use the stabilizer.

I do this a lot and use the Classic Stabilizer in point-track mode. It works very well, except for a *really* annoying pointer-position update bug if you're stepping single-frame through the tracking process.

It's on the color page.

This video might help with what you are wanting.

This might be exactly what I was looking for.

As Bruce suggested, above, you can also use the stabilizer on the color page - use the 'Classic Stabilizer' from the 3-dot menu and then select 'Point Tracker' from the drop-list. Leave only pan and tilt checked (top of panel). Add a tracking point (lower-left of panel) and move it to the point you wish to keep motionless. Track forward and back (double-arrows) and after the tracking is completed, click on the 'Stabilize' button. Since 'Zoom' (at the bottom of the panel) is checked by default, the image will zoom in to hide the exposed borders.

Tried this on a subject walking toward the camera, using her dominant eye as the tracking point - looked great. Using Fusion is slower, but I would definitely use it if the tracking plane was more complex than a single point.

Well, unfortunately, neither of those options worked, for me.
The issue is that they both seem to require whatever is selected to stay visible, the entire time.

In this instance, I'm rock climbing.
I tried a square around my body (the Fusion video idea) and it didn't track me at all.
Then, I tried my face.
The issue with that was my face turning away from the camera.
I tried some of the gear, hanging from my harness, and it stopped following that.

Now, what might work well is the new AI auto-framing function of 18.5 Studio.
I'm not hip on spending $300, but it could be worth it.

Thanks for the ideas, though...

Smart Reframe might do this.

Not sure what versions will have it available.

I find it interesting that I can test the Super Scale with a watermark, but the Smart Reframe option isn't even visible on the free version.

Not entirely true. You can stop the tracker at any point, select a new feature to track and then track ahead from there. You can also switch to frame mode in the tracker to make manual tweaks (adding keyframes) here and there.

Smart Reframe might do this.

I just wanted to update this.
I purchased Studio and have been using Smart Reframe.
It does exactly what I was wanting.
I take my 2160p portrait video, put it in a 1080p landscape timeline, frame myself as I want, and let it go.
It does a pretty good job.
