In one embodiment, an apparatus may include a processor circuit and a keyframe indexing module that is operative on the processor circuit to map sensor data from a first sensor to a set of video data, where the sensor data and video data correspond to an event. The keyframe indexing module may be further operative on the processor circuit to identify one or more key portions of the set of sensor data, index the one or more key portions to respective mapped one or more video frames of the video data, and generate a first keyframe index to identify the one or more video frames.
