While having no issues with swapping out/tracking larger displays, I am having a rough time getting steady corner pins for handheld mobile devices. Despite what appear to be rock solid tracks for two different handheld mobile devices, the inserted GUIs seem to be wobbly. Even microscopic movements by the hand holding the device seem to exaggerate the GUI movement. I have tried tracking almost everything visible in the scene, from the phone to stationary objects with no luck. I have spent two days going in circles for a 1.5 second shot. ANy thoughts?
Have you tried using adjust track? That should fix your wobble woes immediately. https://borisfx.com/videos/quick-tip-adjust-track/
Please let me know and I’ll be happy to help you further.
