Topic: speed measurment 8.26 km/h


Maybe a bug or maybe i mis understood.
i have a video and want to measure the speed of a shuttle.
when i set the speed to KM/h and follow trajectory it is still showing pixels/s
Do i do something wrong or is this a bug?

You need to add a calibration line somewhere in the video and tell its physical length, so the program knows the mapping between pixels and distance. Add a line and then right click and choose calibrate.

This will work only if the camera is standing still on a tripod.

You can also use the more advanced perspective calibration where you calibrate the dimensions of a rectangle.
