A recording device, such as a video camera, emits audio watermarks (e.g., audible tones, inaudible tones) and records audio watermarks emitted by other recording devices. The audio watermarks provide information (e.g., data) such as an identifier of the camera and the identity of the operate. Audio watermarks may further include time information such as a timestamp indicating the time that the audio watermark was emitted by the camera. Audio watermarks may be emitted and recorded at intervals while recording an incident. A processing system, such as a digital video and audio processing system, may receive video information and recorded watermarks from multiple recording devices. The processing system may use the audio watermarks recorded by each recording device to determine which recording devices were in the vicinity of an incident. The processing system may also use the audio watermarks to align (e.g., synchronize) the video recorded by the various recording devices. Alignment of recorded video may permit synchronized playback of the recorded video from the various recording devices. Alignment may further identify at what point during an incident a recording device began and terminated recording.

A method for generating optically machine readable code is provided. The method includes capturing an image with a user device, automatically generating, by the user device, an optically machine readable code comprising information about the image recorded during the capturing of the image, and associating the optically machine readable code and the image. A computer readable storage medium storing one or more programs and an apparatus are also provided.

Aspects of the present disclosure include a computer-implemented method for generating a data-enriched video feed. The method can include: pairing a camera feed of an aerial vehicle (AV) from a flight session with a telemetry feed of the AV from the flight session; converting a set of pixel coordinates within the camera feed into a first set of geospatial coordinates using the telemetry feed of the AV from the flight session; and rendering a data-enriched video feed including the at least one set of feature data, including a corresponding second set of geospatial coordinates, superimposed onto the first set of geospatial coordinates within the camera feed.
