After switching from manual to autotracking, the autotracked data is unavailable

The jig that releases my dropped objects clutters the video and confuses autotracking, so I have to manually track the falling object until it clears the jig support. I then use cntrl+shift to set up a key frame, click the search button, and the autotracker works well to the last frame. But while the manually tracked data usually* plots and populates the table, the autotracked data is never appended to either the plot or the table.

This also occurs for the online version.

Is this "normal" behavior for Tracker? (I seem to remember both manual and autotracked points were recorded when I first started using the app.) Is there a way to get at the autotracked data?

The mp4 video files are typically 120 frames or less. I'm using Tracker 6.3.3 on a Windows 11 desktop.

Possible curveballs: While the video is 30 fps, I set the frame rate to 240 fps in the clip settings, which is the rate at which the dropped objects were originally recorded. I also set the Calibration Stick to something less than 1 m (though the online version refused to accept that).

*Sometimes the manually tracked data fails to plot or populate the table.

The data generated by the autotracked points can be displayed by clicking the Refresh button near the right end of the toolbar and choosing Refresh. This behavior was introduced only in the latest version (6.3.3) so I suggest you use the previous version by setting the preferred Tracker version to 6.3.2 in Tracker preferences.

There will be a new release (6.3.4) before the end of the month that fixes this :-)  Doug
