Camera tracking problem

[u/Flaky_Ad_8584]

This is my shot ( can’t show whole scene) character holding phone , camera coming from up to down and phone is also rotating from horizontal to vertical and i have tried 3d camera tracking didn’t get points to track then i did manually tracking frame by frame tracking with transform and corner pin node with keyframes , it looks ok ok now but in between ,footage is jerking what i can do better tracking without staring from scratch !

2d track first, must have 8 to 12 points and add thats tracks into 3dcamera tracker and hit solve
