GPS data may be used to increase accuracy of GPS time of the image capture device. GPS time of the image capture device at a later moment in the capture duration may be used to determine the times of earlier captured video frames. ## Claims ### Claim 1 A system for utilizing Global Positioning System (GPS) timing, the system comprising: one or more physical processors configured by machine-readable instructions to: obtain video frames captured by an image capture device during a capture duration, the video frames captured at different moments in the capture duration;
