Topic: Logitech C920 - Cameras speed (fps) unstable when using two webcams
Hello Kinovea users,
Recently we started small project (so called ''Falcon eye'') for local Wikimedia (Serbia) and idea is to create kinograms (Diaporama) of various sport activities and sport movements. For this purpose we bought two Logitech C920 HD pro web cameras, we run Windows 7 64 bit operating system. At first use of cameras not possible at high resolution because of drives, when drivers are installed all went fine with one camera, recording runs smooth with resolution of 1024x768 at 30fps. Problem comes when we connect two cameras at the same time, we adjust both cameras at same resolution and fps (1024x768 at 30fps) but fps on both cameras ''goes up and down'', sometimes fps goes over 100 fps at one camera, when we record video (simultaneously record control) with Kinovea (beta 0.8.22) make sort of ''damaged'' video file, you can view it, this is not problem but in some moments video slows down, or speed up or you find some missing frames.
Do you have suggestion how to solve problem? Thanks in advance!
