Want to change your webcam shape? Are you bored of using the same 4:3 or 16:9 cam boxes? Ever wondered how some streamers use cool shapes for their camera — like circles, triangles or vertical rectangles? What about webcam frames with rounded corners, or cutouts and indents along the borders?

Well, it’s easier than you might think — and it’s all done using a filter called webcam masks, or “image masks”. All you need to get started is a webcam source, plus OBS or Streamlabs Desktop.

In this tutorial guide, we’re going to show you:

  • What are webcam masks?

  • How to create masks with Photoshop (optional)

  • How to use basic masks in OBS and Streamlabs

  • Tips and tricks for using advanced mask designs

Don’t have Photoshop? No worries. We’ve created a free pack of 21 webcam masks for you to download and try out on your stream:

What are webcam masks?

Webcam masks are filters within OBS and Streamlabs that allow you to hide parts of your camera source. By masking your webcam, you can choose which areas you want visible to your audience — and which you want to be invisible. This allows you to create cool shapes and cut-outs along your camframe’s borders.

For example, let’s say we want our webcam to have rounded corners. We would create (or use) a mask that conceals the sharp, 90-degree corners of your webcam. Everything inside the new, curved edges will display within your webcam feed. Everything outside will be hidden.

Sound tricky? Don’t worry, it’s way easier than you may expect. We’ll show you step by step how to create and set up your camera mask. Image masks are a super-easy trick that every streamer should master. And they come with some special benefits:

  • They look amazing and will help your stream stand out from the crowd. The vast majority of broadcasters are still using the same 16:9 or 4:3 boxed webcams.

  • Many of the best overlay packages require image masks. You’ll need to know masking basics to use advanced webcam frames like these.

  • They’ll help your stream run faster! Any time you limit the scope of your webcam, you’ll help save on compression bandwidth. And that means less lag and more FPS.

  • Masks help to remove some of the dead space within a traditional webcam frame. This ensures that your viewers are focused on you — and not the wall behind you.

So how do you find image masks? Well, you can either create one of your own, or you can download one from our free pack of 21 streamer masks. If you’re a DIY streamer or designer, check out the next section to learn how to make your own masks within Photoshop. If not, skip ahead to the following section to learn how to set up your mask within OBS or Streamlabs.

How to make a webcam mask

Anyone with basic Photoshop skills can jump in and create webcam masks. While complex masks might take a bit more practice, the process is virtually the same no matter what shape you’re making:

  1. Open a new Photoshop project. If you don’t have Photoshop you can download a free 7-day trial here.

  2. Select your canvas. Are you using a 16:9 or 4:3 camera? Chances are, you’re probably using a 16:9 webcam — in which case you’d want to use dimensions of 1920 x 1080 pixels. If your camera is 4:3, choose a 1600 x 1200 pixel canvas.

  3. Set the background fill to black. By default, any part of your webcam in this black background layer will be filtered out (i.e., made invisible) by your mask.

  4. Create your image mask. Add a new foreground layer and set the fill color to white. This white area represents the part of your webcam that will be visible to viewers. The layer itself can be any form you’d like; experiment with different shapes and borders until you find one you like!

  5. Export your mask. Once you’re ready, we’d recommend saving as a JPG or PNG — your preference.

Just remember — everything in white will be shown; everything in black will be hidden. White, visible. Black, invisible. Make sense?

Now that you’ve got your new image mask in hand, let’s start setting it up.

Basic webcam mask setup

It’s easy to set up your webcam mask in Streamlabs or OBS. In fact, the process is nearly the same across both software — aside from a few small UI differences.

We’ll start with Streamlabs, and then show you where things might be different on OBS Studio.

Setting up webcam masks in Streamlabs (basic)

Here’s what setup looks like on Streamlabs Desktop:

  1. Add your webcam source, if you haven’t already. Go to the Sources tab, select +, then select Video Capture Device. Name it something recognizable (like “Webcam”), then select your camera device from the dropdown menu.

  2. Add a webcam filter. Under the Sources tab, right-click your new webcam source. From the menu select Filters, then select + in the next window to add a new filter. By default, the Filter Type should be set to Image Mask/Blend — so just select Done.

  3. Add your webcam mask. In the next window, select Browse next to the Path field, then navigate to your new image mask to open it. If you picked the right canvas size in Photoshop, your mask should fit nicely over your webcam source. Select Done.

  4. Optimize your camera layout. Now that your mask has been applied, you’ll be able to resize and reposition your webcam without affecting the image mask. When scaling down, always hold the CTRL key and drag inwards from the corner — so that your webcam retains its original aspect ratio.

It’s as simple as that! We’ll show you some advanced tips and tricks shortly, but first let’s cover OBS.

Setting up webcam masks in OBS (basic)

Webcam masks in OBS and StreamElements (OBS.Live) are nearly identical, with a few small differences:

  1. Add your webcam source by locating your Sources tab and selecting + icon. From the menu, select Video Capture Device, then name your webcam source. From the device dropdown menu, choose your camera and select OK.

  2. Add a webcam filter by right-clicking on your new camera source, then selecting Filters from the menu. In the next window you’ll see OBS has two different filter types: Audio Filters and Effect Filters. Select + under Effect Filters, select Image Mask/Blend and give your new filter a quick name.

  3. Add your webcam mask by selecting the Browse button next to the Path field. Navigate to your new image mask and open it. The mask should automatically appear as an overlay over your webcam. If it doesn’t fit correctly, go back into Photoshop and make sure you’re using the right image dimensions.

  4. Optimize your camera to fit your unique stream layout. Resize your webcam by holding the CTRL key and dragging the corner inwards. Reposition as needed by clicking and dragging. Your mask should remain unchanged, despite the transformations.

And there you have it! Once you’ve mastered these steps, you’ll be able to use most basic webcam masks — including the 21 free masks we’re going to give you later!

Advanced webcam mask setup

For many streamers, a basic understanding of webcam masks is enough to get by. However, if you’re using advanced stream overlays — like many of the ones you’ll find in our store — you’ll need to go a bit further. Complex mask designs like these take a few additional steps. Don’t worry, installation only takes a few minutes and we supply you with everything you’ll need.

Among the tips and tricks, we’ll teach you how to add a frame to your webcam mask — one of the most common and important tasks for a streamer. We’ll also show you how to create a webcam scene, which will house all your webcam elements and apply them across multiple scenes at once.

Setting up webcam masks in Streamlabs (advanced)

Once again, we’ll start out with Streamlabs Desktop:

  1. Create a new scene by clicking the + button in the Scenes tab. We recommend naming it “Webcam Scene”, or something similar.

  2. With your webcam scene selected, add your camera source by selecting + under the Sources tab and selecting Video Capture Device. Name it “Webcam”, select your device and select OK.

  3. Add your image mask by right-clicking the new webcam source, selecting Filters, then choosing Image Mask/Blend. Select Browse next to the path field, then locate and open your webcam mask. Next, select the dropdown menu next to Type — make sure Alpha Mask (Alpha Channel) is selected. Once done, close the window and return to the Streamlabs dashboard.

  4. While your webcam scene is still selected, add a webcam frame by creating a new source. Select Image and name it “Webcam Frame”. Next, open your webcam frame file, which should be in the same location as your mask. Your webcam frame should appear in the scene preview.

  5. Now you’ll want to optimize your webcam frame, since it will not initially fit the full size of your canvas. To enlarge it, simple right-click the frame, select Transform and choose Fit to Screen. Your webcam frame should now be aligned with your camera and mask. Once done, all your webcam elements should be successfully combined into a single scene.

  6. At this point, you may want to use your webcam scene as a source within other scenes — like your intermission or gameplay scene. To do this, select your destination scene under the Scenes tab, then press + in the Sources tab. In the next window, select Scene then choose your new Webcam Scene. Resize your camera (hold CTRL and drag in from the corner) and reposition to fit your unique layout.

Now your camera, image mask and webcam frame can all be used in any scene you’d like! Neat huh?

Setting up webcam masks in OBS (advanced)

There are a few small differences for OBS Studio, but overall the process is quite similar:

  1. To create a new scene, click the + button in the Scenes tab. Name it “Webcam Scene” for easy identification, then make sure to select it.

  2. Add your camera source by selecting + in the Sources tab. Select Video Capture Device and name it “Webcam”.

  3. Now, add your image mask. Right-click the webcam source and select Filters from the dropdown. In the next window, select + underneath the Effects Filters tab, then select Image Mask/Blend. Select Browse next to the Path field to select and open your mask file. Next, make sure Alpha Mask (Alpha Channel) is selected in the Type dropdown. Once ready, close the window and return to the OBS dashboard.

  4. To add a frame for your webcam, make sure your Webcam Scene is still selected, then click “+” in the Sources tab and choose “Image”. Now locate and open your webcam frame files, likely in the same folder as your mask.

  5. Readjust your webcam frame by right-clicking it, selecting “Transform” from the dropdown menu, and clicking “Fit to Screen”. Now all your webcam elements have been combined into a single scene.

  6. Want to add your new webcam to other scenes? Simply select the scene you want to add it to, then press “+” in the Sources tab. From the dropdown, select “Scene” then choose your Webcam Scene. From here you can scale your webcam down and reposition it as much as you’d like.

  2. Open your webcam frame: Pick the frame that matches the webcam mask you are using. For example, if you already applied the “Hexagon” image mask to your webcam, select the “Hexagon” frame. This will ensure your mask and frame align correctly. Click done.

  3. Add a color correction filter: Back in your Sources tab, right-click your new webcam frame source, then select “Filters” from the dropdown. In the next window, click the “+” icon, then select “Color Correction” from the “Filter Type” menu.

  4. Change your frame color: In this new window, locate the “Hue Shift” slider. Adjust the selector up and down until you find the right color match. You can ignore the other slider options for now. When ready, click “Done”.

Pretty easy, huh? Keep experimenting until you find the perfect mask + frame combination for your stream.
