Cannot add tracks for 2D Stabilization I'm unable to add Tracks For Location or Tracks For Rotation / Scale in v2.79. The + button is greyed out. Why would that be?



I opened my video file in the Movie Clip Editor, added a few markers, tracked them, ticked Display Stabilization and 2D Stabilization and Autoscale.

It was suggested in the comments that I should click first "solve". None of the video tutorials that I saw on YouTube indicated that I should so that, though. I ticked "Tripod" under "Solve" and then clicked "Solve Object Motion". It made no difference.
The only tracks created for camera can be used for stabilization.




Select markers and copy them Ctrl+C
Select (in N side properties panel): Objects -> Camera
Paste markers here Ctrl+V
Now you can use copied markers for stabilization
