What is GPS Log?
GPS Log is a feature that allows location information and the movement speed to be recorded while recording movies when using the GPS function of the camera. The PlayMemories Home™ software installed in your camera allows you to import movies recorded with the GPS Log to a computer and view these files with a map showing the location information.
NOTE: The maximum number of 256 log files can be recorded per day. Log files are not recorded when the maximum number is reached, but you can continue to shoot images.
