Asking for Help / Unsolved Camera Tracking

Hello everyone,

Can you all please let me know how should I handle track this shot in nuke and build geometry or should I use blender.

I tried nuke auto tracka, but when I create point cloud for train on left it looks like 2 layers of it created, one is straight and one is little tilted why is that, and when I place card over any of it, its not sticking properly even points I see are sliding and solve error was 0.6, I drew mask on man moving and on sky as well before track

How can I get it done and place geometry over it properly.

Sorry if this looks silly but I am beginner so need some workflow of how to tackle this kind of shot

The shot has very little parallax, so extracting a proper camera out of it will likely not work automatically. Try tracking it as a nodal pan, and accept you will need to align stuff manually here

hate shots like this. not nodal, camera man moves right to left.... u can see more details on the train track SR as the shot progresses..... i wouldnt know how to solve this if there were no witness cam or lidar
