[Review] Logitech HD Pro Webcam C920. Does it work on a Mac?

I've seen that many of my friends on Google+ who produce live video hangouts love using the Logitech HD Pro Webcam C920.

So I've been happy to recommend it and the previous model, the C910.

Some features of the C920 that are most appealing are:
- H.264 encoding
- Full HD 1080p recording
- Tripod Mount
People do get confused though from the Logitech requirements page for the C920 where it says:

C920 Technical Specifications:
OS Support (at release) - Windows XP x32 / x64, Windows Vista x32 / x64, Windows 7 x32 / x64
No mention of it working on a Mac, at all.

Then there's this:

Taking full advantage of the H.264 Logitech C920:
To take full advantage of the H.264 codec with your Logitech C920 webcam:

- If you're using UVC drivers instead of Logitech drivers, you'll need an app that supports UVC H.264 extension.
- If you're using Logitech drivers, you can take advantage of the H.264 codec using the DirectShow app in Windows.

NOTE: For H.264 preview, you'll need an H264 decoder. Microsoft bundles this with Windows 7.
Um, UVC drivers? What are they?

I'm on a Mac. We don't do drivers.


Looking further, I want to see if my favorite live streaming software, Telestream Wirecast, might support the C920 despite the system requirements above.

Wirecast 4.1.4 Release Notes [PDF]:
New! Support for Logitech C920. (Mac OS X & Windows)
Here's the Wirecast 4.2.2 Release Notes [PDF] if you are interested in the latest.

So let's take a look at the camera and see how it performs.

Yes, the C920 has a tripod mount. This is great!

The C920 connects to the Mac via a USB port. Despite the requirements on the box, the camera shows up on a Mac as Logitech Camera.


I tested it out first, as a still camera, with Photo Booth.

Here's the first photo:

Compare that to the FaceTime HD camera on the Thunderbolt display and MacBook Air.

Logitech HD Pro Webcam C920 Wins


- Video test
- Microphone test

My first test was with the C920 and it's on board microphone using Photo Both again, to record video.

Make sure you go into system settings first to set the microphone input to HD Pro Webcam C920.

Logitech HD Pro Webcam C920 Mac Video Test

I exported this video with Photo Booth as a quick test, and then uploaded it to YouTube. Video quality is great. Sound isn't quite in sync. I'll need to do more testing with QuickTime and Final Cut Pro X to test both HD and sound. Stay tuned.

When you upload a video file recorded with QuickTime Player, you get this message from YouTube:
For better results, adjust your Quicktime settings to prepare videos for internet streaming. For more information, visit our Help Center.
Over there all the export settings are listed out to make sure your audio and video are in sync.

QuickTime Player Video:
I ignored those instructions, recorded a new video with QuickTime Player Video, and uploaded the raw video file. It came out ok.

Take a look:

Click the settings button on the video and change the resolution to 1080p to see the best quality.

Another Test:

Recorded this video with the C920 using QuickTime Player, Audio Technica AT2020 USB mic, imported into FCP X, edited, exported with compressor, and uploaded to YouTube.

In FCP X the audio seemed a little out of sync, but when I exported for YOuTube, the audio seems fine.

This time I used the YouTube 1080p export settings, but still got a warning from YouTube. Looks and sounds good anyway.


Logitech HD Pro Webcam C920 Works on a Mac

I cross-posted a link this review over on Facebook and am getting lots of comments from people who use the C920 as their primary camera for web video. Take a look.

The C920 is not officially supported on the Mac by Logitech.

For settings, I'm told the Mac App, Webcam Settings By Mactaris, $7.99 in the Mac App Store, allows you to control the C920 Webcam Settings.

- Google+ Hangouts

  1. One thing I noticed straight away though. The Logitech C920 photo test seem to add much more detail to the photo. The other 2 cameras were not able to pick up the other person that the Logitech C920 photo test. You've sold me!


  2. Hey Steve,

    I just got one of these cameras, and the problem I'm having on my Mac is that it defaults to 640x480. I want more pixels and 16-9. I can't find a utility or control panel that will change this setting. ???

    1. Hi Jack,
      Which app are you using?

      1080p worked for me using QuickTime Player.

    2. On my Snow Leopard Mac Book Pro it will only record 1080 at about 5fps. Obviously not acceptable.

  3. So this camera will work for facetime also?

  4. Have you noticed that it does not seem to stay in focus on mac os x 10.8.2 on Google Hangouts? or Hangouts on air?

    1. I can test this, but I see online that someone with a focus problem had to exchange their camera.

    Thanks for your review! One question: does the face-tracking feature of this camera work on the Mac? Say with Skype?

    So... I'm using my Mac Mini as my HTPC with a Samsung Smart LED TV and was looking for a webcam compatible with Mac. I like your review and I think you may have just sold me on this product BUT... How is the video quality with Facetime? I only ask because that is my primary use since most of my contacts like to use Facetime (for obvious convience reasons) instead of using Skype. Thanks for your feedback!

  7. Hi Steve, long time no talk, great post. Looking at the 920 and I'm reading all sorts of conflicting reports about it working with Macs. I'm going to use it with Skype(often) Facetime(sometimes), tired of the two monitor setup where people see the side of my head when I'm looking at the big monitor and the cam on the MBP is off to the side.

    Does the Webcam Settings By Mactaris app unlock all, or some of the controls that appear to be non-functional with the camera out of the box on Mac?
    Just did a Skype call with someone using the $30 C310, looked fine to me. I could do with the 615 model as well but I'm in the mood to splurge and go for the 920.
    Any thoughts since you posted this? Thanks!

    My initial efforts at using the c920 on a mac.

    mac air 11" 1.6Ghz i5, mavericks,

    qt7pro, quality setting "device native", produces 8 seconds of 844x475 video at 1.18gb? 7+gb per minute? is that correct? looks great but seems a little steep on the size. changing the qt quality setting to "high" produces 640x480 video. And looks good for that resolution, and creates significantly smaller files sizes (understandably) but no HD. I can't find a way to try 720p recording in qt7pro.

    Hold on. if i use qt10 at "high" (not "maximum"), it gives me 720p at 10.92 mbit/s (compared to 998.7 mbit/sec in qt7pro at "device native"). Looks okay, NOT great, but okay. And at 1% of the size! And having the quality set to "maximum" in qt10 & qt7pro crashes qt after a couple of seconds. But it will render 1080p. key seems to be using qt10 at "high" quality to get 720. Otherwise I need a faster machine. I think....

    Thus far, a little confused and frustrated. I have googled extensively and find people reviewing this cam on macs and, as you did above, and are able to produce 1080p vids. And many others, like myself, who can't. I have concluded that it is a power issue (for processing, not electrical), but that seems strange if the encoding is taking place on the camera. One person was excited that he could use this cam and produce 1080p videos on his Macbook Air, but I can't find any followup of him succeeding in the year that has passed.

    Hate to ask, but I would be really interested, given that you are using a Macbook Air, that perhaps a step by step tutorial might be in order. Maybe my problem is Mavericks. Dunno. Not a newbie, or at least, never thought of myself as one when it came to macs until now. Or maybe you see something in my setup above that explains what I'm missing here.

  9. Old post , but I thought I'd add something. You mentioned the "Webcam Settins" app . In addition to the "Webcam Settings" app , the "iGlasses" app will control the C-920 on a Mac, allowing manual control over exposure/color/white balance/focus/digital zoom. I actually prefer "iGlasses" over "Webcam Settings".
