Getting Your Webcam to Look Good in OBS Without Spending 45 Minutes on Filters

The Default OBS Webcam Looks Like a Security Camera Feed

You add your webcam to OBS, resize it, drag it to a corner, and that's what most streamers stop at. A plain rectangle. It works, technically, but it looks unfinished compared to streamers who have a clean circular webcam with a colored border and a soft glow behind it.

The gap between those two looks is smaller than you'd think, but getting there manually in OBS is genuinely tedious.

What Getting a Circular Webcam Normally Takes

If you've tried to make a circular webcam in OBS without any extra tools, you know the process. You need a circular mask image, usually a PNG with a white circle on a black background. You add an Image Mask/Blend filter to your webcam source. You hunt down or create a mask file that's the right size for your webcam resolution. You add the filter, point it at the image, and then discover your webcam is the wrong aspect ratio and the circle is actually an oval.

You then spend time adjusting crop filters, resizing the source, recalculating dimensions. If you want a border, that's another source, usually a circle image you drop behind the webcam. If you want a glow, that's another filter with opacity and blur settings to tune.

Total time if everything goes smoothly: around forty-five minutes. If something is off with your resolution or aspect ratio, longer.

Most streamers either give up and keep the rectangle or find a tutorial video and follow it step by step. Some of those tutorials are outdated and refer to filter options that have moved or changed in newer OBS versions.

What Cat and Mouse Does Instead

Cat and Mouse has a live styling panel built into the app. You pick a shape: circle, rounded rectangle, or portrait. You pick a border color using a color picker. You drag a slider to set glow intensity. Every change applies to your OBS webcam source in real time.

That's it. The whole process takes about two minutes, and you can change any of it mid-stream if you want to try something different.

The app handles all the filter configuration on the OBS side automatically. You don't touch OBS filters directly. You adjust the sliders and see the result.

Why This Matters Beyond Aesthetics

A polished webcam look signals that you've put thought into your stream. It's one of those small things that viewers register without necessarily articulating it. A circular webcam with a clean border reads as intentional. A raw rectangle reads as default.

For new streamers building an audience, getting the visual presentation right early matters. You're competing for attention with streamers who have been at it for years and have refined setups. Closing that visual gap doesn't require expensive gear or hours of setup time.

Changing Your Look Mid-Stream

One thing that's actually useful about Cat and Mouse's styling panel is that changes apply live. If you want to switch from a circle to a rounded rectangle during a stream, or change your border color to match a different scene, you can do that without interrupting the broadcast.

In OBS, changing a filter mid-stream means clicking into the filters panel, finding the right filter, adjusting values, and hoping nothing looks broken on stream while you're doing it. In Cat and Mouse, you drag a slider or click a shape and it updates immediately.

The Primary Feature Is Still the Dodging

The styling panel is a secondary feature. The main reason Cat and Mouse exists is to move your webcam out of the way when your cursor gets close, automatically, without you doing anything.

But the styling panel is why you might find yourself opening the app even on days when you're not thinking about the dodging behavior. It's just a faster way to manage how your webcam looks.

Cat and Mouse is three dollars a month and runs on Windows. You can find it at catnmouse.app. If you've ever spent an afternoon fighting OBS filters trying to get a clean circular webcam, you'll know immediately whether it's worth it.
