The third and final option is to manually synchronize the video and data. This is done by loading in the video and then selecting a particular frame of video and a corresponding point on the data that matches, and then clicking "lock". This is done in the “Run Manager”, in the Data menu:
The synchronization controls are displayed once a video has been loaded in the “video setup” tab
Use a combination of the video play controls, together with the course and fine skip/jog controls to find a particular part of the video, and then click on any graph at the same point in the data – and then click “lock”.
The key to manually synchronizing the data and video is to find a point in the data and video that perfectly match. The simplest way to do this is to make sure that the data logger is within view of the video recorder, so if you start the video recorder first you can see exactly when the data logging starts. Alternatively you can identify in the video and data when the car first pulls away from a standing start, or the first braking point etc.
On this screen it is also possible to select the automatic synchronization options just as if they were used at the time of loading the video file.
Finally note that on this screen you can also see the offset time between the GoPro and the GPS time in the data file that Analysis has stored. In the screenshot above the offset of 4 hours, 46 minutes and 41 seconds is being applied.
