Trying to capture what someone is experiencing when they’re head-first in a VR game has been an interesting problem to crack. By matching up live video and a digital environment with the help of a green screen setup though, you can essentially create a video that places you straight in the action—one that better communicates the immersion of a VR game than a simple first-person screen capture. Oculus recently revealed in a blog post that in the past months they’ve been working on bringing native mixed reality capture support to Oculus Rift, and it’s available today for developers to start creating mixed reality videos.
Oculus has recently published a guide to teach developers how to capture mixed reality with two important tools (besides a VR headset): a green screen and an external camera. The company says developers can create mixed reality content with either a stationary camera or a mobile camera that can be attached to a virtual, in-game object—letting you capture the scene from various vantage points and making the action even more immersive for non-VR viewers.
