Video stabilization in Clip Editor

I followed a tutorial on stabilization using the clip editor and tracking markers. It works up to a point as I follow along the tutorial. But when he scrubs his video, it is stabilized, and there is a reference frame (dotted line rectangle) of the original so you can see how it’s going. When I scrub, the video just plays as it was, with no stabilization and no dotted outline. If I track frame by frame, I do see the red and blue tracks, but that’s all.

There is a checkbox in the clip editor window that shows the current view locked to the active tracker, but it does not get used for stabilising. You just add the tracker to the 2D stabilise list.

This lock view is just to show you ow stable the track is compared to the image. Makes it easy to see drifting or sliding of the track.
