Finalized the function of overlaying either an image or a segmented video from a second camera to the main camera, like on the last example video.
A comprehensive toolset has been developed to create and recall even comprehensive setups of kinovea, allowing post-processing the videos after each recording.
If you are interested, you may send me a PM under reiner(dot)hente(at)gmail(dot)com.
