Yesterday I realised I was looking particularly suave and debonair, so decided it would be the right time to point a camera at myself. Mmm…
If you want to try using a decent digital camera for videoconferencing, you normally either need:
something which will capture an HDMI output signal from your camera and feed it into your computer over USB, like the Elgato Cam Link,
or you need some software which can capture the live preview output and make it available to your operating system as if it were a locally-connected camera. On the Mac, I do this with a combination of Camera Live – which makes it avaliable as a ‘Syphon’ server – and CamTwist, which can take a variety of inputs, including Syphon, and blend them into a ‘virtual camera’ output. There are various tutorials online on how to do this. OBS is a similar popular app, but doesn’t yet support virtual camera output on the Mac.
Finally, for some versions of some Mac apps, you may need to remove the app’s signature (which identifies it with a certain set of permissions), to enable it to see virtual cameras as well as physical ones. At the time of writing, Zoom needs:
$ codesign --remove-signature /Applications/zoom.us.app/
P.S. Sadly, various other people have used the phrase ‘One man and his vlog’, so I can’t pinch it on any kind of long-term basis 🙂
