Opening AVI-files shows black screen

Hello everone,

I use Tracker for processing AVI-files that can be quite large (up to 3 gb) and I used to be able to do that just fine (not sure which version it was, but around June/July 2021).

However, when I open an AVI-file in the latest version 6.0.3, the video screen just shows a black image and I can't do any tracking.

The older version 5.1.5 that is available on the website has a different problem: It can open AVI-files fine, but when trying to open a large video it shows an error message saying "Video could not be opened."

Is support for AVI-files gone or is it something I can fix? Or is there a way to download older versions of Tracker, so I can try those out?

Thanks and kind regards
J. W.

Jo, can you attach or otherwise send us a short AVI clip that fails to open?  Or is it only very long clips that fail? If you have a short one we can do some testing.  Thanks. Doug

I cut down one of our AVI-videos to just 6 frames and attached it here (packed into a .zip because I was not able to attach a .avi).

Tracker 6.0.6 opens the file but only shows a black image. Same as the large videos.

Tracker 5.1.5 opens the video just fine and shows the proper image. However it does not open large videos (> 2GB approximately).

Hope that helps!
