Movie editor at least 8 common tracks

Movie editor
when try solve/camera motion it says that at least 8 common track’s on both keyframes are needed for reconstruction i think i have much more so lets say have 200 frames 100 track’s per frame … how to check which are active where i can see that?

in short i want to know how many active track’s i have per frame
here is a link to video i made with desktop recorder
