Isnt compulsory for me to buy a camera to record the video for motion capture?
Can I use my laptop camera instead?
Thank you


Of course you can use your laptop camera, but as it is facing yourself, it will be very difficult to handle the controls....?
The price for a decent webcams has dropped significantly. I use a Streamplify webcam that gives FHD 1920x1080 at 60fps, for a price of 60 euros.
