Discovery #2. Performing a “lab test” with a very simple generated video, 12 clear features. (I probably could attach.)
Tracking all the way through the footage, 5 tracks stop part way through. Of course “Solve Camera” fails, because there aren’t 8 tracks on first and last frame.
I manually adjust the failing tracks at the interruption points. Playing the clip shows all tracks moving correctly.
“Solve Camera” again gives console errors (“No camera for <every-single-frame>”). This is odd, since the camera hasn’t moved or changed since the first solve attempt. “Track” => “Clear Solution” and retrying does not help. Exiting and restarting Blender doesn’t help. Something must have been cached which I can’t clear, or error messages are misleading.
Same behavior on 2.83.3 and 2.81a which I was originally using.
