There are three types of video camera available in Rec Room, which allow PC users to record short clips of their time in Rec Room. Currently these do not work on PSVR. Live cameras are only available in Paddleball, the other cameras are also available in the Rec Center and Paintball.
Video and Gif Cameras
When held, the video cameras display what they can see. To take a video, hold the trigger down, and observe a red dot and a red progress line on the video output. This shows how long you've been recording and how long you have left on this video. Videos taken on PC save to the directory "Documents/Rec Room". The gif camera records video in (animated) gif format, and the video camera records video in mp4 format. Currently there is no support for sound recording.
When held, this camera displays what it can see on the large jumbotron in the Paddleball hall. When dropped, the last held position of the camera is used. Apart from that, it works like the gif camera.
These cameras are limited to very short videos without audio. Most gameplay videos of Rec Room are captured from the Rec Room desktop window using, for example, the Windows 10 Game Bar , Open Broadcaster Software, or NVIDIA ShadowPlay. You can switch between multiple camera views for this window (including a third-person camera that is following you) using the Stream Mixer in the Advanced Tab of the Settings Menu of your Watch Menu.
