The present disclosure relates to systems and methods video recording and video replaying. The method may include obtaining video data from a video recording device. The method may also include generating an index item corresponding to the video data if the video data includes a key frame, wherein the index item includes an index position of the video recording device corresponding to the key frame, and an offset address used to determine an address where the key frame is stored. The method may further include storing an index table including at least the index item in a video.

Systems and methods for video replaying

The present disclosure relates to a system, method and non-transitory computer readable medium. The system includes: an input port configured to receive a first video from a camera; an output port configured to out a second video; one or more storage media including a set of instructions for modifying the first video; and one or more video processors in communication with the one or more storage media, each video processor including an internal cache memory. When executing the set of instructions, the one or more video processors: obtain the first video from the camera; obtain at least one operation parameter relating to the camera from the input port; generate a target image graphically illustrating an operation of the camera based on the at least one operation parameter; reconstruct the second video based on the target image and the first video; and send the second video to the output port.

Systems and methods for video processing

The present disclosure relates to systems and methods for replaying a video that includes positions of a video recording device. The method includes obtaining a target position of the video recording device corresponding to a target scene. The method further includes based on the target position, searching an index table associated with the video to determine a target index position of the video recording device, wherein the index table indexes a plurality of positions of the video recording device. The method further includes determining an offset address in the index table corresponding to the target index position. The method further includes obtaining a video clip including the target scene based on the offset address. The method still further includes replaying the target scene in the video clip.
