<p>Neither of these cameras offers video out. They are still cameras that can take limited movies, that you can then download using the USB port for bulk transfer.</p>
<p>It's really worth reading the manuals for your cameras - if you don't have them with your camera, they are available for free online.</p>

<p>The only way I have found to achieve this with a Canon, is to use the EOS utility to display the video on your monitor, then use a screen-capture app like CamTwist, to capture an area of your screen and turn it into a virtual camera. Not idea, as anything accidentally straying into that part of the screen will appear in your webcam output.</p>

<p>I tried the EOS utility and cam link USBs but nothing works for the two cameras that I own---canon 5D mark iii or Olympus OMD EM5. I understand that they are pretty old models. I was wondering if anyone figured out how to make it work?</p>
<p>Thanks!</p>
