After we cracked video recording and social sharing for our initial launch of Slapstick, we threw our creative and tech teams at a feature we'd never seen in augmented reality: Post Capture.

Post Capture makes the Slapstick app more flexible, versatile, and user-friendly. Typical AR apps require users to add AR content before recording their video or snapping a selfie. Our Post Capture feature allows editing AR in content that has already been recorded and saved.

We accomplish this by storing the AR environment (i.e. planes and point clouds), as well as the motion and position of the phone's camera while the user records their video. This information is saved to a custom file type that’s recalled when the user enters the Post Capture mode. The app rebuilds the environment so that stickers can be placed in the correlating 3-D space. As the user scrubs through their video, the in-app camera is moved along the saved camera path, which adds the camera motion in the video to their newly-added stickers. Once the user is happy with their edit, the app records a new video that splices together the new stickers and the previous video.
