Video calling is ubiquitous. You can video call your friends, family, and colleagues, sharing your face and surroundings simultaneously. Being in the same location all time is boring, right? How about appearing with your regular face? Everyone knows what that looks like.

What if you could make a fake video call that switched out your face, the background, or other important features—would you fake call your family?

Here's how fake video calls work and how you can spot one.

What Is a Fake Video Call? How Are Fake Video Calls Made?

A fake video call can mean a couple of things.

For instance, you could create a fake video background in an attempt to trick people into believing you're on holiday. You could record a video of yourself staring at your monitor, then play it back during a meeting that you are not required to talk in.

There's the option of mirroring your webcam input to a YouTube video that does not feature you at all but could show an amusing cat video.

A fake video call could also use deepfake technology, using AI-powered video to switch out the faces and voices on display. You can find more information on deepfake tech later in the article.

How to Make a Fake Video Call Using ManyCam

How you approach making a fake video call depends on the platform. On a desktop computer or laptop, you have multiple software options to use a fake video, but your access to certain apps is limited. However, the WhatsApp desktop app now allows voice and video calling, so the following instructions also allow you to make a fake call using WhatsApp. Still, most fake video calls use freely available PC software.

For those apps you can use, ManyCam allows you to alter the appearance of your webcam extensively. For instance, you can use more than one webcam with Skype or other voice-calling apps or stream a completely different video that appears instead of your webcam.

Here's how you make a fake video call using ManyCam.

1. Configure ManyCam

First, you need to download, install, and configure ManyCam.

Download: ManyCam for Windows | macOS

Once your download completes, install ManyCam.

2. Create a ManyCam Preset & Choose Your Fake Video Source

You can use presets for your fake video call. Open ManyCam, then under Presets, select Preset 1. Underneath the Presets panel are the video source options. Select the video source you want to use, such as a webcam, IP camera, YouTube video, web source URL, and so on.

If you want to use a YouTube video, copy and paste the video URL into ManyCam. Do the same for whichever fake video source you choose.

3. Select ManyCam In Your Voice Calling App

You can make your video call once you configure the fake video source. But you must select the ManyCam webcam option in your video call app to display your fake video. The process is slightly different for each video calling app, but you'll find the ManyCam Virtual Webcam option in the camera or webcam options.

How to Select ManyCam in Skype

In the Skype desktop app, head to Settings > Audio & Video. In the Camera options, select the ManyCam Virtual Webcam. When you make your video call, the fake video in ManyCam will play instead of your regular webcam.

How to Select ManyCam in WhatsApp Desktop

After following the above instructions, open your WhatsApp Desktop app and locate the person you want to call. When the call dialog appears, select the three-dot icon, then select ManyCam Virtual Webcam from the dropdown menu. The video call will display the video playing in ManyCam to the person you're calling, and hilarity will ensue. And that is how you make a fake WhatsApp call with ManyCam.

How to Make a Fake Video Call Using OBS

OBS (Open Broadcaster Software) is a popular cross-platform, open-source video streaming tool. You can use OBS to stream to multiple platforms simultaneously, record media, and much more. In this case, you can use OBS to stream a fake video in place of your webcam.

The result is similar to ManyCam. However, as OBS is completely free, you can use the full range of video streaming and broadcasting options. Even though OBS has more tools on offer, the software isn't difficult to use.

Here's how you make a fake video call using OBS.

1. Configure OBS

First, you need to download and install OBS. Although it is a cross-platform tool, the following steps only work with OBS on Windows due to the plugin required to create a virtual webcam.

Download: OBS for Windows (Free)

2. Configure OBS-VirtualCam

OBS-VirtualCam is an open-source plugin for OBS. The plugin creates a virtual webcam option in OBS. Once you install the plugin, you can output media to the virtual webcam, then select the virtual webcam in your video call options.

While the VirtualCam plugin once required you to download and install it manually, as of OBS version 26.0.0 (launched in August 2020), virtual webcam functionality is now built into OBS directly. You can still install the plugin if you want, but it is no longer the most efficient way.

So, within OBS, head to Tools > VirtualCam and select Start. The virtual webcam option of "OBS-Camera" will now appear in your video calling apps, such as Skype or Facebook Messenger.

3. Select Your Fake Video Source in OBS

OBS has several options you can use for a fake video. You can use OBS to play a local video, display a browser window or online video, create a video stream from a third-party video player (such as VLC), and more.

You can see the range of options along the bottom of the main screen in OBS. Under Source, select the + icon, then choose the video input option for your fake video call.

  • If you already have a video you want to use, select Media Source, then browse to the file location on your computer.
  • Alternatively, you can play the fake video in a separate media player. Select Window Capture, then select the media player using the Window dropdown menu.
  • If you want to use an online video, select Browser, then input the website URL you want to display. Next, resize the browser window using Width and Height to fit the video size.

Whichever video configuration you choose, the result will play through the OBS-VirtualCam virtual webcam in your video calling app.

Can You Make Fake Video Calls Using a Smartphone?

Smartphone apps come with a different set of limitations regarding fake video calling.

Fake video apps for smartphones are a dime-a-dozen, but they don't do what you expect. If you search for "fake video calling apps" on Google Play, you'll find thousands of poorly coded apps that let you "chat" with a fake person rather than stream a fake video through a video calling app.

Spoofing a smartphone camera within an app isn't easy. Smartphone video calling apps (and other apps in general) don't allow such behavior for a simple reason: it presents a security risk. If one app can spoof and mimic the camera for a fun reason, another app will use the same process for nefarious reasons. So while you can make a fake call on WhatsApp Desktop, you cannot do the same using WhatsApp on your smartphone.

Alternatively, you'll find fake video call apps that appear to give you the option to make a deepfake (more on these below) to make a prank call but are actually just face-swap apps.

What Is a Deepfake?

On the more nefarious side, there are deepfakes. A deepfake video uses AI technology to create an extremely convincing video featuring the likeness of someone else. Deepfake tech continues to develop, and it is becoming increasingly difficult to spot the difference between a real video and an AI video. For example, check out the example that brought deepfake technology to light, mimicking Barack Obama:

The hands and gestures are Obama's, but the mouth (voiced by comedian Jordan Peele) is out of sync. Whereas just over one year later, The Dark Knight's Tale features Heath Ledger playing himself as Joker in The Dark Knight, but also in A Knight's Tale.

The Dark Knight's Tale is fake. But it does illustrate the tremendous advances in deepfake technology over the course of a year.

Around the same time, a deepfake featuring Facebook CEO Mark Zuckerberg was also illustrating the technology.

Again, it is clearly fake. Zuckerberg sounds completely different from the deepfake.

How AI Is Affecting Deepfakes and Fake Video Calls

But where deepfakes once required a tremendous amount of computing power, advances in deepfake technology and artificial intelligence processing have made the process much easier. Picking out high-quality deepfakes is becoming difficult, as evidenced in the video below.

In addition, AI voice generators are easily accessible and, with enough source material, can be trained to sound deceptively similar—enough to make AI voice generators a security threat.

How to Spot a Fake Video Call

Can you spot a fake video call? The answer lies in the quality of the fake video.

The development of deepfake technology is a prime example. Jordan Peele's deepfake video mimicking Barack Obama was clearly fake. But the quality of public-facing deepfake technology is much better than it was, and that's without considering the deepfake and AI technology that powerful organizations or governments will have access to. Regardless, protecting yourself from deepfakes is important.

At other times, you'll know a fake video call is false because of the contact information. Making a truly fake video call on WhatsApp Desktop is incredibly difficult because the contact information is on display during the connection. Similar limitations are present with other video calling apps that link to a phone number, such as making a fake video call with FaceTime.

There are, of course, tricks to skirt these issues—fake accounts, fake phone numbers, false names, pictures, and so on. But for the most part, would someone go to that length to create a fake video call to fool you?

For most people, tech support scams are a more pressing issue. Either that or the threat of phishing scams relating to the latest news cycle.

5 Ways to Spot a Fake Video Call

In short, there are a few tell-tale signs regarding a fake video call:

  • Video quality. The quality of the video is usually poor. If the fake video comes from an online source, check for watermarks or other signs the video is stolen.
  • Video sizing. Whoever is fake video calling you will resize a video to fit the webcam window or the app they're using. Resizing the video will distort the proportions of the video, so it looks out of shape (think extra long or extra wide face, and so on).
  • Contacts. Is the person calling you on your contacts list? If not, does the name mean anything to you? Alternatively, does the contact name appear as the name of an app?
  • Content. If the video call comes from someone you know, and their contact information is correct, what is the video content? Is the person allegedly calling you even in the video?
  • Loops & Cuts. Many fake videos will loop around to the start after a certain amount of time elapses. Alternatively, the video will stop abruptly at the end—but the video call won't finish.

Also, if someone is using a face-swapping app with video functionality, the faces are extremely unlikely to align correctly. For example, using a tool like Avatarify can bring an avatar to life for use in a fake video call, but the motion of the face won't be seamless.

Fake Video Calls Be Gone!

Now you know a few of the methods used to make fake video calls and which platforms they work best on, you're better prepared to spot and avoid them. Fake calls using software like ManyCam work, but unless you're using exceptional hardware, a fake video call is usually easy enough to spot.

Mobile apps like WhatsApp and FaceTime have built-in security mechanisms to prevent fake video calling and other scams. In reality, it comes down to just taking a moment to double-check the facts on offer, such as the phone number, video quality, and so on.

Furthermore, while making a fake call using an app or an online tool seems fun, using fake video calls to deceive or harm others could potentially have legal consequences, especially in cases of identity theft, fraud, or harassment.
