Autotracker search frame stuck
No Juan
1 Posts

When autotracking a ~500 frame 720p video (only 110 frames are being tracked) the search box gets stuck half way down the image. I can't move it further down the Y-axis even manually although I am free to move it above the line at which it stops. This is not a visual glitch becuase the auto tracker refuses to add points below the dotted line of the search frame. When recalculating the search box with a new key frame it still does not move below this invisible line. I have uploaded the tab file and video, restarting tracker and opening the tab file does not fix the issue so hopefully this will be reproducable.

Thanks

NoJuan

Edit: I am using Tracker 6.0.3

Hi NoJuan, somehow the trk file and video did not get attached. Can you try that again? I'd really like to try to reproduce and fix this!  Thanks. Doug

Seem to have entered my email wrong so this is a different account. (-_ლ)
Here is a .zip with the two files, it is larger than 2 MB so I can't upload it. Here is a link instead: https://drive.google.com/file/d/1QTrIELByGFjcatGPZ0W79eZ6qYlzjMRA/view?usp=sharing
