The long jump rules were changed in 2021 to the jumper not crossing the vertical plane of the line on the board - using plasticine is not enough anymore, but the board should be checked by video. The available systems are pretty expensive, so i wondered if the Kinovea could be used for this:
A high quality smartphone or GoPro/clone with the highest possible resolution and 60+ fps connected by USB?
Kinovea is very handy when using the recording&playback screens, placing a virtual line to the board, recording the take-off and quickly swiping the clip to the playback, where one can zoom in at the details....and save the clip to be reviewed later if necessary.
The needed resolution is probably higher than HD (2K?) and fps 60-120?
Could this be achieved?
