How-To: How to Resize Your iPhone’s Webcam on Mac

If you have a Mac Ventura and a device that supports iOS 16, the iPhone camera can be used as a Mac webcam. It’s a very useful feature, but the problem is that it’s not easy to properly position the iPhone so that the screen is visible. The iPhone video screen cannot be cropped or enlarged or reduced while recording. Therefore, the user must use the screen seen from the iPhone’s rear camera or front camera as it is. However, the following two programs can solve this problem.

When not using FaceTime – OBS

Apple does not natively support virtual webcams. If you want to use a virtual webcam separately, you have to use an external program, the most popular is OBS(Open Broadcaster System). OBS, an open-source program and free to use, has built-in virtual camera software. Previously you had to tweak a few technical settings, but now the virtual camera software is just a click away.

In OBS, you can select your iPhone as the video source, just like FaceTime and other apps. Click the plus sign under Source, select Video Capture Device, then choose your iPhone from the Device pop-up menu. If everything works, you’ll see a preview of the iPhone view, just click OK.

You can now crop the screen size smaller than it appears by default by dragging the handle of the red rectangle. Now click Start Virtual Camera from the Controls menu (located in the lower-right corner of the screen by default). Then select the OBS virtual camera in Zoom or any other video conferencing or video app. OBS can add title, audio, window, etc. For details, refer to the official documentation and forum.

If you find the OBS program too difficult to master, it is a video presentation system that allows you to combine audio, video, slides, screens and other sources. Ehh(mmhmm). Uhmm outputs the video taken on the iPhone directly to the video conferencing software. You can use the basic function of enlarging or cropping the screen with the free service alone.

When using FaceTime – Camo

If you need to use Camera and FaceTime together, Reincubate has created camoLet’s use a program called Camo. It is the only virtual camera software that can fully integrate with macOS Video. Basically Camo creates a virtual camera compatible with Apple software. However, zooming and other adjustments require a paid license.

The Camo app is available for iPhone, iPad and Mac. Instead, you’ll need iOS 12 or higher and Mac OS 10.13 or higher. Windows 10 and 11 are also supported. The device you want to connect can connect to your Mac via USB or Wi-Fi. With an app called Camo Studio on MacOS, you can select your iPhone or iPad’s camera and then apply zoom, rotation, effects, watermarks or image adjustments. The output screen works in the form of a virtual camera.

Camo’s free version only supports screen sizes up to 720p, but doesn’t include zoom or other features. If you want to use Camo, try the free version first for testing purposes. A subscription to Camo costs $4.99/month or $39.99/year, or $79.99 for lifetime use. The paid license covers up to 2 computers and can remove the watermark.
