Hi Neil,
Another method you might try is using Mocha AE. I brought the footage into Mocha, tracked it. Then eyeballed and quickly added some keyframes and it did a pretty good job, more time would get a better result. Saved it, created Masks from the Matte data. Then I created a shape layer, add a path, copy and pasted the mask data into the path and finally added a stroke.
There’s some drift in the lower left area and the middle level on the right side. That’s where you will probably need to add the most time to dial it in.
I uploaded my project file for reference.

Adding on to the above, your tracking is fine, you just have a very very large composition. if you zoom out the shot out to 100%, the stars stop jumping around. If you put this composition into your final comp, if it’s standard aspect and used as the background, it will look fine.

It’s happening because when you add or subtract text from the textbox, the text layer’s anchor point doesn’t move when the amount of text changes. So I updated the project, on the subtext’s anchor point, I added an expression:
r = sourceRectAtTime(time, false);
[
r.left + r.width/2,
r.top + r.height/2
]
This will recenter the anchor point no matter how much text you put in the SubBox.
I parented the SUBHEADING TEXT to the SUBHEADING BOX, the 0,0 the position. This way, if you have some ascenders or decenders, you can just offset the Y value of the position to make it more visually centered.
In the new example project, I offset it just so you could see the adjustment.

I rebuilt some of the expressions using width and height pad sliders, rather than a fixed margin on the box sizes. The anchor points for everything have to be centered.
To create the fixed gap, I added an expression to the position of the Subhead Box, using the sourceRectAtTime command to references the bottom of the Heading box. I added a gap slider to the subhead box, so you can adjust that width easier.
Lastly, I parented the Subheading text to the SUBHEADING BOX, 0,0 out the position and it’s stays with the SUBHEADING BOX.
If you are building a motion template, you might want to delete all the expression sliders and just enter fixed values if you don’t want people messing with them.
You can see everything in the example project.

Are the boxes being generated by the position of the text, using sourceRectAtTime ?

Do a multipass render and use the OpenEXR file format. In AE, apply the the 3D channel – EXtractoR effect to your Buffer pass, then you can access the different buffers. I made an example setup for you to examine.

Well, the final product looks nice, good job, sorry you didn’t get paid.

I don’t use blender, so I’m not sure what is causing the issue. As far as fixing it, I would just choke the matte, using one of the matte effects like “Simple Choker” or “Matte Choker”.

You could use the rd Comp Setter script. Set up each precomp, then when you make your final renders, use the script to change the size of all the precomps at one time. I use it all the time for changing frame rates, comp sizes, etc.

I’m a little flumoxed, because before I posted my answer, I tried to use the Num Key * and it didn’t work for me. I saw Chris’s replay, and I just started AE again, and tried again and it is working for me. It might that my first project was too complicated to playback in realtime, not sure. But Chris is right and you should be able to use his approach.
Sorry for the confusion.
