Does your webcam exceed the dimensions of your custom overlay? Do you need to crop out an area of your room? Sometimes you need to crop a webcam image in OBS Studio (Open Broadcaster Software) before you can stream on Twitch, Facebook Gaming, or YouTube Gaming.

Fortunately, you can use this simple method to quickly change the size of your video source with your mouse.

    This article will cover how you can crop or resize the source selected in OBS Studio so that you can create the content you wish.

    How to Crop Webcam Source on OBS Studio

    Whether you use a green screen or show your background, it is important to know how to crop your webcam in OBS. This way, you can ensure that your viewers are able to see the rest of your screen. This will allow you to show off more of the game you are playing.

    To crop your webcam image in OSB Studio, use the inbuilt crop feature by following these steps:

    Step 1

    If you haven’t already, add your webcam to OBS Studio by adding it as a source. Once you can see it in your preview window, you’ll be able to move on to the next step.

    Stop cropping when you are satisfied. While you can keep to the aspect ratio if you choose, you can make your webcam in OBS Studio any rectangular shape you wish when using the edit transform option.

Decorate Your Cropped Screen

Once you have cropped your webcam, you can remove the background with a chroma key screen or decorate it with stickers or overlays. Try to keep things on brand, matching your colors, themes, and the style of content you produce.
