I know what you're thinking, and the answer is yes… I made that video with Soapbox!
Or maybe you weren't thinking that, and you have no idea what Soapbox is. If that's the case, check out our new webcam and screen recorder for Chrome, then come on back.
As soon as I started testing early versions of Soapbox, I was tempted to try an external webcam, rather than the built-in camera on my MacBook Pro, to improve image quality. I couldn't help myself—I'm a video nerd! I plugged in my Logitech c930e USB webcam and saw a modest quality improvement over the FaceTime HD camera.
It's a little black box that converts any HDMI signal to USB 3.0. Not only that—the AJA U-TAP doesn't require any software or drivers. It essentially enables you to use an HDMI signal as a webcam.
A webcam for video nerds
Using the AJA U-TAP, you can turn your favorite video camera into a webcam. In order for this to play nicely with Soapbox, your camera must transfer audio with the video signal over HDMI. Not only that, it must output a "clean HDMI" signal, free from on-screen displays.
Using the AJA U-TAP, you can turn your favorite video camera into a webcam.
These factors mean that some cameras won't work well with the Soapbox setup. For example, the Canon 5D Mark III has clean HDMI output, but the audio doesn't transmit over HDMI, which renders it unfortunately unusable.
As a result, our camera of choice for this setup is the Canon 5D Mark IV (the newest 5D in Canon’s lineup). It checks all of these boxes and adds another killer feature—autofocus with facial recognition. This makes it very easy to keep things in focus, even if you move about a bit during the recording.
We're still in the early stages of testing a multitude of other camera options, but I can confidently say that along with the 5D Mark IV, the entire series of Canon Cinema cameras (C100, C100 MKII, C300, etc) will work perfectly.
Here's how to turn a Canon 5D Mark IV into a webcam:
1. Plug Mini-HDMI into 5D.
2. Plug HDMI into AJA U-TAP.
3. Plug AJA U-TAP into USB.
4. Select the U-TAP as the audio and video device in Soapbox or whatever webcam recording tool you're using.
Some additional tips for this setup:
- On the 5D, shoot at 29.97 frames per second for smooth motion capture.
- You'll be using camera audio, so you could plug an external microphone into the camera, such as the Rode Video Mic.
- Consider using a basic tripod head on top of an apple box behind your laptop to make framing the shot easier.
- We use the 24mm f/1.4 lens based on the camera placement. It sure is a wide lens, but it actually best mimics the characteristics and focal length of your laptop's built-in webcam.

You might be tempted to save some money and pick up the Magewell HDMI to USB converter, instead of the AJA U-TAP, but I promise you'll be disappointed. We tested it out, and while it does enable you to view HDMI on your laptop, it struggles with motion stuttering and sync issues.

The AJA is worth the extra money in this case. It's held up to long periods of being plugged in, and it seems to be a reliable device so far in our testing! For the record, we have not been paid by anyone to make these claims, or given free product samples—this is just my genuine opinion regarding the best gear to use.
Using other cameras
Calling all cameras! I really wanted to find a budget point-and-shoot camera that would work with this setup, but so far I've struck out. We bought a few different sub $800 cameras to try out, but none of them checked off both boxes (transferred audio over HDMI and had a clean HDMI video output).
Do you know of other cameras that have clean HDMI out? Does audio follow the video over HDMI? Does it have facial tracking? If so, it might be an awesome candidate to use as a pro-quality webcam with Soapbox. Let us know in the comments!
