I'm sure this must be something I have just overlooked or misunderstood, but I cannot for figure out why I can't solve camera motion in this situation.

I have 8 tracked points, with seemingly very smooth motion, yet when attempting to solve camera motion it refuses giving the "At least 8 common tracks are needed on both key-frames for reconstruction". My keyframes are at frames 0 and 67, the same as was set for solving. Yet I still get nothing each time.

Here is a short clip of the situation for additional context.

You can see that the 8 points track from 0 to 67 then stop, yet that range for solving does not work.

Thanks in advance for the help.
