Integrating video feeds and wagering-game content

A wagering game system and its operations are described herein. In some examples, the operations can include receiving a video feed of a casino wagering game presented live via a first device. The video feed depicts at least one first symbol from a set of wagering game symbols used for outcomes of the casino wagering game. The operations can further include, after receiving the video feed, compositing a computer-generated image with the video feed to generate a composited video feed. The image represents at least one second symbol from the set of wagering game symbols. The operations can further include providing the composited video feed for presentation of the casino wagering game via a second device separate from the first device.
