Can't set the position of an external webcam

Hello,

i tried to add a usb webcam in Arena (Version 1.7.0) to get a video with an overlay of the captured skeleton like it is possible with optitrack cameras used as scene cameras.

Unfortunately changing the settings of the new scene camera like X,Y,Z or the corresponding offset fields had no effect on the overlay which i see when i choose the webcam in the viewing pane while capturing.

Could anybody tell me what these settings affect and if it's only possible to get an exact overlay in arena when I use optitrack cameras?

Best regards,
Bjoern

Hi Bjoern,

In order for marker overlay in scene video to work, the scene video camera must be calibrated into the system along with the tracking cameras. Only OptiTrack cameras can be calibrated by ARENA. So, the functionality that you're looking for will require that you convert one of your tracking cameras to a scene camera, or purchase an additional V100:R2 to act as that camera.

Hi Seth

Thank you for your answer, we will order an additional optitrack camera during the next days.
