Looking for some tracking help – probably quite basic!
Hi all,
So I have a property edit and need to create a highlight ‘outline’ over a block of apartments in a drone shot which orbits around the building. I’ve done this with no problems on previous shots, where the shot duration has been shorter and the shape doesn’t have to change much with its movement – some slight keyframe nudges here and there to correct any drifting.
This shot is longer and the camera movement more extreme, so the shape of the apartment in the space changes quite a bit over time. I’m using the 3D camera tracker, creating a solid and camera, precomping, then creating a shape layer that matches the shape of the building in the precomp and deleting the solid. However, there’s too much drift and the building shape changes too much to correct by keyframing.
How would you recommend I can approach this to get my 2D outline to lock on to the shape of the building and remain locked through the shot?
Thanks in advance!

Hey Bro! send me the uncompressed clip and i’ll send it solved for you + project files and a tutorial with my full method. In case you’re ready, Let’s do it

Thanks John, that’s really kind. Where should I send the clip?
-
drop a drive or a wetransfer link or if you wanna keep it extra private, send the link as a message to my profile
-
Thanks John, I’ll send you a WeTransfer link. Here’s a reference image in the meantime with the outline specs
-
I should also add there’s an 18 frame trim path drawing the outline on!
-
good, shoot the link when you’re ready to do this

ok Neil here’s the full tutorial with 2 working methods for this, hope you like it a little bit! 🔥

John, that’s amazing, thank you for your time and effort on this. I did try method one originally but didn’t like the results – it still felt a bit ‘wavy’ in places. I’ll give method 2 a go now and see how I get on!

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.
