See extraction rate is 0.5 (i.e. one frame every 2 seconds).

However, see the extracted frame times below.

They are all 0.1 seconds apart.

Note, the extracted time is not super important here BUT the GPS points are. It is vital we align extracted frames with the correct GPS point reported in the video.
