Selecting 2D source point in 3D camera tracker

Postby McLaniel on 12/3/2018, 1:35 pm

Hi everybody!

I hope you can help me on something. Im using Camera 3D Tracker on a clip, I have analyse it and in the category ''show track point'' I selected 2d source because those point fit more with the mouvement of the clip. The probleme is that, compared to 3D solved, I can't right click on those point to create a null from them. The only option they give me when I right click on them is to delete them. I wanna know how to use the track point in 2d source mode!

Thanks in advance ☺

You can create a 3D null, and get the screen-space coordinates thereof with this expression:

Code: Select all
L = thisComp.layer("layer-name-here");
L.toComp([0,0,0])
