Why does the 3d text move so much??? Please help

[andrej_4912]

I have recently started using ae and I wanted to make the 3d text stay on the bridge. I have tried redoing the detailed analysis multiple times and everytime it becomes the same. No matter which points i choose it still moves. When i place ground and plane then it stays where I would like it but as soon as i change the angle or move the xyz axiys a tiny bit it goes back to moving alot. Idk what to do anymore. It was shot on a dji drone if that makes any difference. The average pixel error is 0.9

It didn't help I think that the issue is that I was tilting the camera up and that could be throwing it off. Do you have any idea what I could do to fix it??

You need to set an origin and ground plane, ensuring they align with the surface. Then, add a camera and a solid to verify that the origin remains stable. You then need to find 3 points on the surface where you want the text to ride and add another solid to make sure that the solid sticks to the surface. Once that is done, you can add a Text layer, make it 3D, and then use the Shift + Parent command to attach it to the solid. 

I think the only thing wrong with your shot is that you did not pick the right tracking markers.
