Optimize your webcam setup for mmhmm

Webcam video quality is one of the most important aspects of a high-quality presentation. Learn how to get the most out of your camera setup with these tips.

Built-in webcam


If your computer has a built-in webcam, that's great! You’re ready to use mmhmm.

External webcam


mmhmm works even better with an external HD webcam. External HD webcams provide higher image quality and greater control of your recording angle compared to built-in webcams.

Here are some external webcams we recommend using with mmhmm:



It may be possible to use your DSLR camera as an external webcam. DSLRs have the highest quality image sensors and allow for a greater variety of lenses which can produce a richer image and be more suitable for some types of broadcasts. The following DSLR manufacturers offer webcam software:

Note: If you're having trouble using Canon EOS Utility with mmhmm, try the following workaround (only applicable to Macs with Apple Silicon).

  2. Open Finder and go to Applications.
  3. Find and right-click the mmhmm app, then select Get Info.
  4. In the app info window, select the Open using Rosetta checkbox.


If you use a DSLR from a manufacturer that doesn't provide their own webcam software, you'll need a capture card such as the Elgato Cam Link 4K to process your camera's video feed. Check Elgato Cam Link 4K's compatibility with your DSLR.

Smartphone camera
