However, recording Roblox videos can be challenging, especially if you're on a tight budget.

From adjusting your graphics settings to using free screen recording software, we'll cover everything you need to know to get started. So, let's jump in and learn how to record Roblox videos like a pro!

Use OBS to Record Roblox Gameplay

If you don’t have OBS installed on your PC, navigate to obsproject.com. You can download the installer for Windows, MacOS, or Linux. In our example, we will download the OBS installer for Windows. The download will take a minute, and your browser can help you find your downloaded files. After the installation is done, simply double-click this icon to open up OBS.

Create Scenes in OBS

To get started, make sure that you have a scene set up. A scene is composed of different sources. We will create a scene to record my computer screen. Click on the plus icon to create a new scene. You could also rename your existing scene.

Display Capture Source

Next, we will need to add a Display Capture source. Name it whatever makes sense for you.

Click on Ok, and leave the Capture Method option to Automatic if this option is available for you, and below select the correct display that should be captured. You also have the option to prevent OBS from recording your cursor, but I like to keep this option enabled. Next, when clicking on Ok, the source will be added, and you should be able to see your screen.

Properties for the OBS display capture source

Game Capture Source

You can add a Game Capture source, which will only record your Roblox window and not the entire screen. This can be beneficial when not playing in fullscreen mode. Ensure Roblox is running in the background and select to create a new Game Capture

Under Mode, select Capture specific window. Under Window, select the Roblox.exe window. When clicking Ok, you should see the Roblox window in your OBS preview.

Resize Sources

If you are using an abnormal screen resolution or if OBS is displaying a zoomed-in screen for other reasons, then you can resize and change the way OBS records your screen. Simply click and drag the handles on the sides to resize your image. You can also use the shortcut CTRL + F to zoom out and recenter your screen recording image quickly. When holding Shift while resizing, the image will recenter and adjust the image to the height of the recording canvas.

Video Capture Device

Add additional sources, such as a Webcam. Select Video Capture Device in the OBS sources drop-down menu to do so.

OBS Audio Mixer

Move your attention to the Audio Mixer panel. This will allow you to decide which audio sources will be picked up by OBS and ensure that none of the sources are too loud or too quiet. Your Desktop Audio is the sound from your PC. Your Mic / Auxiliary slider lets you change your microphone input volume. You might have other audio sliders below, such as your Video Capture Device, your webcam or another microphone.

When clicking the gear icon of your Microphone sound input, you can add filters that will allow you to improve your overall microphone quality by using a Noise Gate, Limiter or Compressor.

To quickly optimize your OBS recording settings, you should use the Auto-Configuration Wizard.

Under Tools, select the Auto-Configuration Wizard option, and you will be presented with three options. According to your preference, OBS will adapt your recording settings. In this example, we will Optimise OBS for recording and not streaming, so choose this option if it’s according to your preference.

Click on Next, and set the Base, or Canvas resolution to your native monitor resolution. Set your FPS option to Either 60 or 30, but prefer 60 when possible. This will allow OBS to choose the best option, depending on your CPU and GPU usage.

Record Roblox

To record your Roblox gameplay, select Start Recording, and Stop Recording again when you’re done. When navigating to File, you can choose Show Recordings, which will open up your default folder where OBS recordings will be saved.

Best OBS Settings to Record Roblox

To add shortcuts to start and stop recordings or change your default folder, open your Settings. Under Output, navigate to the Recording tab. You have the option to change your Recording Path. Click on Browse, and choose an existing or create a new folder in your file explorer to where your OBS recordings should be saved.

OBS Studio > Settings > Output > Recording

OBS Video Settings

Under Video, you can rescale your output resolution if you wish to do so. This can be helpful for users with a wide screen aspect ratio, for example. We prefer the Lanczos Downscale Filter, as it will provide the sharpest recorded video, but you might want to reduce it to Bicubic if you’re using a low-end PC.

OBS Hotkeys Settings

Under Hotkeys, you can set custom shortcuts to start and stop streaming, start and stop recording, pause your recording, and much more.

Advanced OBS Settings

Under Advanced, we suggest setting the Process Priority option to Above Normal. This will ensure that OBS will run fine if other resource-intensive applications are also running on your PC. After applying your changes, you can record your Roblox gameplay for free using OBS Studio.
