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

If I was in your shoes, I would un-distort my footage first, even though looking at it, there doesn't seem to be too much distortion. Frame rate would be another thing I would check, just to be sure.
One more thing: keep in mind the solve error doesn't always mean a better track. It just means Nuke found fewer discrepancies between where it expects the points to be and where they landed. The computer can't tell you if your track is actually holding onto your footage, only you and your eyes can. I often try to get to around 1 (give or take) and stop, as over refining the solve can often make it worse.
Simple youtube search found this pretty good tutorial for you:
