The Ultimate Guide to the Rounded Corner Overlay Maker
The Rounded Corner Overlay Maker is a specialized tool for video editors and livestreamers. It generates custom, transparent PNG overlays with precise cutouts, allowing you to place perfectly rounded facecams or screen-captures over your gameplay or presentation footage without needing complex masks in OBS or Premiere Pro.
Who Will Use This?
- Twitch Streamers: Create custom overlay frames (with soft edges or continuous "squircle" curves) for your facecam that easily import into OBS Studio.
- Video Editors: Generate 16:9 or 9:16 layout templates with multiple transparent cutouts to easily composite reaction videos or picture-in-picture content in Premiere Pro or DaVinci Resolve.
- UI Designers: Quickly generate semi-transparent backdrop overlays to highlight specific UI elements in a presentation.
How to Create Your Custom Overlay
- Set Canvas Resolution: Choose your target video size (e.g., 1920x1080 for HD desktop or 1080x1920 for mobile/TikTok). This ensures your overlay fits your video editor timeline perfectly.
- Style the Overlay: Pick the color and opacity of the background (the area that will cover your video). For a subtle dimming effect, use black at 50% opacity.
- Add Cutout Boxes:
- Use the sliders to adjust the Width, Height, and X/Y position of the transparent hole where your facecam or secondary footage will show through.
- Adjust the Corner Radius to round off the edges.
- Use Border Softness to blur the edges of the cutout for a smooth, feathered transition into the video beneath.
- Click + Add Box to create multiple cutouts (perfect for split-screen layouts!).
- Upload a Test Background (Optional): Under PREVIEW CONTEXT, you can upload a screenshot of your gameplay. This image is strictly for preview purposes so you can align your boxes perfectly; it will not be included in the final download.
- Export: Click Export Overlay (PNG) to instantly save the transparent file to your computer.
Common Problems & Tips
- What is the "Continuous (Squircle)" style? Standard rounded corners look like a straight line that suddenly turns into a circle. A "Continuous" curve (popularized by Apple's iOS app icons) uses a mathematical bezier curve to make the transition between the straight edge and the corner completely seamless.
- My overlay is completely black in my video editor: If your video editor does not support PNG transparency by default (or if you accidentally converted the file to JPG), the transparent holes will render as black. Always ensure you are importing the original PNG file.
- I can't select my second box: Make sure you click the "Box 2" tab above the sliders to switch which cutout you are currently editing. The tab of the currently active box will be highlighted yellow.
Frequently Asked Questions
Will the preview background I uploaded be saved in the final image?
No! The preview background is automatically hidden when you click Export. You will only download the transparent overlay itself.
How do I use this in OBS Studio?
Add an "Image Source" to your OBS scene, select your exported PNG file, and make sure this Image layer is placed above your game capture and facecam layers in the OBS source list.
