Many times you want video footage besides kinematic data. The video that you can get from Qualisys Oqus cameras might be super large in size and many times, as the cameras are mounted at height, yo may not capture the video from sideways (normally for gait analysis). Qualisys itself suggested Blackmagic Intensity Pro card to connect non-FireWire cameras. Using the card, you will connect the output of your camera (component, one yellow video and two read and white audio output) to the card and on the other side, you will connect the card to your computer with QTM installed on it. With a price of 200$, it does not seem to be a good option.
Here is a cheaper option:
You need:
1- One Audio-Video Grabber: Basically, it is the cheaper and simpler version of Blackmagic (£7).
2- Component cables of your video camera: Almost all cameras have this useless cables. With the introduction of HDMI, almost no one uses them anymore. If you want to have higher quality video with this method, you have to buy an HDMI adapter for AV Grabber as well (I did not test this).
Here is what you have to do:
1- I was using QTM 2.11 on a 64bits Windows 7. I connected the AV grabber to the computer and it started to recognize the USB. The driver was not successfully installed and I did not have any CD.
2- I downloaded EasyCap W7 Driver here (alternative link) and extracted the folder on my PC.
3- Right click on My Copmputer > Properties > Device Manager
4- In your Other devices, you see USB 2.0 Video Capture Controller, with no installed driver. Right click on it and select "Update Driver Software" and then "Browse my computer for driver software", then hit "Browse" and locate the folder you already extracted on your PC. Proceed forward and ignore the "Windows Security" warning by selecting "Install this driver software anyway".
5- After installing the driver, unplug the USB cable. Now turn on your video camera and adjust the output settings (select to transfer images to component output), connect the component cable to the camera and USB, and finally connect the USB to your computer.
6- Now open QTM and go to "Tools > Project Options > Input Devices" and select "USB2.0 ATV" from the right side with a green light saying that it is enabled.
You can now enjoy the cheap solution. You can use your video camera as a Skype camera as well.
