How to Use a Green Screen Virtual Set in OBS

OBS stands for Open Broadcaster Software and it is a fantastic option for video producers looking to create live video streams to Facebook, youtube and more. With the ability to perform real time chroma key / green screen effects and other live elements, it is one of the best options for live production. And best of all, it is 100% free!

OBS GREEN SCREEN: The Movie

For those that would rather watch a tutorial, here is a video version of our OBS green screen tutorial. It's packed full of catchy tunes, fancy text work and a special guest appearance by a very famous Jedi apprentice!

For those who prefer the written word, proceed to the blog post below.

STEP 1: Setup a Green Screen & Film Your Presenter

Hang your green screen behind your presenter/subject/jedi, setup your lights and position your camera. In our video tutorial, we used a webcam, but you can use either a webcam or another camera that you can use as a video input device on your computer.

When lighting your green screen, be sure to remove as many wrinkles as possible from your green screen materials and light the screen as evenly as possible. This will help the computer to remove just the green from your scene.

STEP 2: Start OBS Create a New Scene & Name It

Open the OBS software (available as a FREE download here: XXXXXXXXX) then create a new scene and name it.

STEP 3: Create a New Video Capture Device Source & Select Your Webcam / Video Source

In the bottom left hand corner of the screen, create a new video capture device/source and select your webcam or video source.

STEP 4: Double click your Webcam / Video Source to Configure the Video

To configure your video source, double click it in the source list. You can then adjust zoom, crop, focus, sharpness and apply a chrome key to remove the green screen in the scene.

STEP 5: Adjust Zoom, Focus, Sharpness, etc..

Adjust your zoom, focus and sharpness in the configure video source panel.

STEP 6: Scale and Position Your Presenter

Using the scale and position tools, scale and position your talent / presenter in the scene.

STEP 7: Add a Chroma Key Filter to Your Webcam / Video Source

Right click your webcam / video source and click filters

STEP 8: Add a Sharpen Effect to your Video if Desired

If your video seems a little soft/fuzzy, try adding a sharpen filter as well.

STEP 9: Add Chroma Key Effect to Remove Green Screen

Add a chroma key effect to remove the green screen in your scene.

Choose Chroma Key Type

Select either color type or custom color to sample your green screen for removal.

STEP 10: Drag & Drop A Virtual Set

Close the filter box after you are happy with your chroma key. Next, drag a virtual set from finder / windows explorer to your source list. OBS accepts mp4, jpeg, PNG and many other file types to be used as background sources.

STEP 11: Loop Virtual Set

If you are using a looping video for your background, double click the loop name to display the input properties. In the properties, you can set the clip to loop.

STEP 12: Re-Position Presenter in Scene

If needed, re-position your presenter in your scene.

STEP 13: Create Variations of The Scene

Now that you have your main scene setup, you can easily duplicate your scene and make changes to the backdrop and position of your presenter that you can then recall live during your stream.

STEP 14: How to Change Scene During a Production

To transition between scenes you have created, you can simply select the scene in the bottom left hand corner of the screen and OBS will automatically transition between the scenes.

Using this technique, you can use multiple virtual sets, angles and scenes to create a varied broadcast.

STEP 15: Adding A Monitor to the Scene

If you would like to add a tv monitor to your scene you can either add a scene that contains a monitor or just add the video feed and scale / position the video into your scene.

In our example, we have a monitor with a green screen in it, we will add a chroma key effect to the virtual set source and remove the green in the monitor to show the b-roll video on the layer below.

STEP 16: Adding B-Roll Video

Drag and drop video and/or images into your scene area from finder / windows file explorer.

STEP 17: Scale and Position B-Roll Video

Coffee tastes have changed so much that I remember around 2012. It's is after all the seed of a fruit. From then on, we began to work at a gradual pace, turning up the brightness a little, season after season. Today we can proudly craft a coffee with notes of lemon meringue, strawberry or passionfruit and find people on all sides of the counter are learning and developing their pallets.

You're Done!
