3d tracked line motions on real life footage (after effects),How to do it? reference video attached

The good news is that you have most of the basic tools you need already in After Effects (assuming you’ve CS6 or later) such as Mocha AE and AE’s 3D Track Camera. You have to track the footage in order to create the data needed to tie other elements to it. There are tons of tutorials and such out there and you’ll just have to weed through it to find what’s pertinent to you. There’s youtube of course but Boris FX (https://borisfx.com) bought Imagineer Systems (creators of Mocha) last year so check out the tutorials there as well as searching https://vimeo.com for older but still useful ones. Check the MochaAE forum as well: https://forum.borisfx.com/c/mochaae

The down side is you’ll still need some additional tools in order to create 3D geometry for your overlays. Those could range from a myriad of scripts or plug-ins for After Effects itself, to full blown 3D animation programs. In any case, there needs to be some means of exchanging data (null positions & 3D camera data mostly) between the two and not every package has that.

In short, there’s no simple & quick answer so just keep persistant.

Thanks..Really hope if i could use help of some plugin that i can tie with after effects to get the results,than diving in trying to learn the scripts.
