3D Camera track fail

I understand it's frustrating when things don't work. But expecting to be able to track a rotating red square with no texture, contrast, detail, or depth shows a lack of understanding about motion and camera tracking. So many things factor into a succesfull camera track. If your shot has a lot of motion that is seperate from the camera movement (people walking, cars driving, etc) it will be difficult to track. If your shot goes in and out of focus it will be difficult to track. If there is any zoom in or out, difficult to track (when you zoom in, objects appear to get closer to the camera but the camera is not actually moving, and this can confuse trackers). If there is no object or feature that stays in frame throughout the entire shot, difficult to track. If there is any lens distortion (common with wide drone lenses) or rolling shutter, difficult to track. Just to name a few. 

Things you can try:

• In Effect Controls, under 3D Camera Tracker>Advanced, try changing the Solve Method. Check all of them and see if any work. 
• Shot Type: If there is any zooming in or out in the shot, change shot type to variable zoom.
• Use lens correction on your shot to remove any "fisheye" type lens warping around the edges of the frame. If a tree looks slightly curved, it's because the lens distortion is warping the picture. This can make it impossible to reliably track the camera.
• You may not even need to track the camera. If you're doing a simple insert or object removal, just do a point track. Or use Mocha AE and do a planar track, which can be useful for drone shots but can also be frustrating until you understand how to use it. 

If you want to supply the drone shot you're trying to track, I can take a look at it and let you know if there's anything else you can try.

You can't successfully 3D Camera track a rotating solid as there is no depth data in the scene for the analysis to process. It's not a valid scenario for the feature.

As for your drone footage, how long is the shot and to what extent does the implicit "scene" in the footage change entirely?

If the scene content changes entirely, such that nothing in beginning of the shot is still in frame at some point, there will no longer be any image context for the analysis to process successfuly — the initally estabilshed 3D space will be gone entirely. This will be an issue with any 3D tracker you try.

You may need to break the footage down into separate scenes.

But with only the minimal details you provided, and no sample footage to demonstrate the issue, this is really only a guess.

Sorry to hear about the issue. Is it happening with a specific footage? Can you try with a different footage? If possible, can you share the media here so that I can try testing it? Feel free to DM me the download link if you prefer not to share it publicly. A rotating square does not have enough details/camera movement to track.

Looking forward to your response. Moving this thread from Bugs to Discussions for troubleshooting.
