Abstract: A loop recording system allows users to remotely save and share short recorded video, audio, or combination clips using portable devices equipped with cameras, microphones, and sensors. The loop recording system enables users of portable devices, such as smartphones, tablets, smart watches, etc., to record moments of interest during live events (hereinafter called “loops”, “recordings”, or “loop recordings”), while preventing unwanted data loss and conserving memory resources of the portable device. In exemplary embodiments, the loop recording system has loop recording intervals that can be defined by the user or can be predetermined, certain recordings can be automatically saved rather than overwritten, and/or the number of recordings that are saved may be programmable by the user or predetermined. The loop recording system can also prevent unwanted erasure of data, facilitating the tagging of loops, sharing of loops, and enhancing the loops using post processing means.
