Open Mask Generator →What is a Camera Mask?
A camera mask is an image that hides parts of your webcam. It's how streamers get:
- Rounded corner webcams
- Circular facecams
- Custom shapes (hexagon, star, etc.)
- Decorative borders and frames
Method 1: Image Mask (Recommended)
- Create or download a mask image (black = visible, white = hidden)
- In OBS, right-click your webcam source
- Go to Filters → + → Image Mask/Blend
- Select your mask image
- Type: Alpha Mask (Alpha Channel)
💡 Mask Image Rules
Black areas stay visible, white areas become transparent. Use PNG format with transparency for best results.
Method 2: Overlay Frame
- Create a PNG frame with transparent center
- Add as Image source in OBS
- Position it over your webcam
This method adds decoration but doesn't crop the webcam itself.
Common Webcam Shapes
- Rounded Rectangle - Most popular, subtle and clean
- Circle - Classic look, great for corner placement
- Hexagon - Unique, tech/gaming aesthetic
- Pill Shape - Modern, YouTube-style
Best Webcam Sizes for Streaming
| Placement | Recommended Size |
|---|---|
| Corner (1080p stream) | 320×240 to 480×360 |
| Full screen | 1920×1080 |
| Just Chatting | 960×540 or larger |
FAQ
Does a camera mask affect performance?
No, image masks use minimal resources. It's just hiding pixels.
Can I animate the mask?
Yes! Use a video file instead of an image for animated borders.

Open Mask Generator →Advanced Techniques: Animated Borders
A static border is good. An animated border is memorable. Here are three ways to add animation to your webcam frame in OBS:
- Animated PNG (APNG) border: Create a looping frame animation in Photoshop or After Effects, export as MP4 or GIF, then add it as a Media Source in OBS positioned over your webcam. This gives you glowing, breathing, or rotating border effects.
- Shader plugin borders: The OBS ShaderFilter Plus plugin allows you to apply GLSL shaders to sources. A glow shader on your border frame can create a pulsing neon border effect with zero video files.
- Chroma key frame: Some streamers use a physical LED ring light behind them to create a colored halo effect that naturally outlines their webcam — no editing required.
Webcam Border Style Guide: Which Shape for Your Content
| Stream Type | Recommended Shape | Why |
|---|---|---|
| FPS / Battle Royale | Hexagon / Circle | Dynamic, tactical look |
| Just Chatting | Rounded Rectangle (large) | Professional, close-up-friendly |
| Music / Art | Circle or Pill | Soft, creative aesthetic |
| IRL / Vlog | No mask (full rectangle) | Natural, unframed look |
| Speed Runs | Small circle (corner) | Minimal screen real estate used |
Frequently Asked Questions
Does a camera border/mask reduce video quality?
No. OBS image masks work at the compositor level — they hide pixels without re-encoding them. Your recording and stream quality are completely unaffected. Performance impact is negligible (less than 1% GPU usage for a static mask).
Do I need a plugin to use a camera border in OBS?
No. OBS Studio has a built-in "Image Mask/Blend" filter that applies any PNG mask to any source. Download your mask from our free generator and apply it through Filters — no plugins needed.
Can I use a camera border on Streamlabs OBS?
Yes. Streamlabs OBS supports the same Image Mask/Blend filter as OBS Studio. The process is identical: right-click your webcam source, go to Filters, add Image Mask/Blend, and browse to your PNG mask file.
