Video capture and encoding is CPU intensive and your system may have performance issues. The greatly enhanced optics, large image sensor, and depth of field provided by a DSLR camera contribute to a much better looking image. It would be great to capture an HD quality image from a large, sophisticated and expensive camera, but in my experience the resolution doesn’t matter as much as you might think. The resolution of the preview frames captured from your camera varies, but will likely be less than 720p (1280x720). gPhoto2’s movie capture mode captures a series of preview frames from your camera and outputs them as a motion JPEG video format. This guide uses the gPhoto2 application and associated libraries, which enables you to control your camera through terminal commands. You will not capture the full resolution of your camera’s image sensor. There are however a few important limitations to be aware of before you get started The configuration as detailed here works very well for most people. You can run from your camera’s battery, but run time will be limited Ideally some way to power your camera through a power supply.

Ability to connect your camera to your Linux-based PC through a USB cable.A camera supported by gPhoto, with Liveview capabilities.

It’s straightforward to get setup within Linux, this is the guide for how it’s done. The depth of field adjustment is what allows for a nice, smooth, blurred background. Using a DSLR provides a number of benefits over an off-the-shelf webcam, most notably higher image quality, ability to finely adjust the frame of an image (zoom, wide angle), and adjust the depth of field. If you desire a more professional looking image when video conferencing, it turns out that you can use a DSLR camera as your webcam.
