Hello

I have a video of a train drivers POV. I was wondering if we can use Kinovea to estimate the speed profile of the train as it moves over the track.

Any help/suggestions?

Thank you

I'm not sure if this would work but assuming there are landmarks on the rail tracks or pylons that are equally spaced, one way might be to use the counter tool and mark one beat each time the pylon gets out of view.

Right now the counter tool data doesn't get exported in the spreadsheet export… that's an oversight. You could do the same adding a full key frame at each landmark crossing event. Then in the spreadsheet you would need to multiply the frame index by the distance between the pylons and that should give you a distance/time series that you could do further calculations on.
