To record video or take photos of what you can see in the Oculus Quest headset, simply click the
button on the main menu bar, as highlighted by the red square in the image
below. Then select the appropriate item from the Sharing menu that opens.
To take a photo, select the item from the Sharing menu. A red dot will appear
within your field of view, and flash for a few moments, before taking a photo
on a timer.
To record video, select that item from the Sharing menu, and recording will
begin immediately. A red dot will again be visible to show that it is recording.
To stop recording, simply select that menu item again.
You can then either share these files through Facebook via the various sharing
options within the headset, or connect the Headset to a computer via the USB
cable used for charging.
