It is possible to take a video of your rowing session and use the [raw-attachment:wiki:WikiStart:talos-rowing.jnlp offline Talos Rowing viewer] to view both the video and the Talos Rowing data side-by-side. 

== How to take the video ==
 1. make sure to turn on the '''session recording sync mark''' feature in your device settings
 1. start the video camera first - point it from close range directly at the Talos Rowing screen
 1. start session recording
 1. make sure the camera is turned on the device while the sync marks are displayed

    ''Note: If you turn the video camera off, pause it, or put it on stand-by mode, you must repeat the above steps again''.

== Editing the video ==
The video must be edited in order to ensure it is synchronized with the Talos Rowing session data file. This is done by deleting the beginning of the video file until the first frame showing the the '''session recording sync mark'''. On my Linux machine, for example, I used a video editing utility named '''avidemux''' to trim the AVI video file created by the video camera. 

== Merging the video with the Talos Rowing session data ==
The product of the following steps is a special OGG file containing both the video and the Talos Rowing session data. The file can be played directly using the [raw-attachment:wiki:WikiStart:talos-rowing.jnlp offline Talos Rowing viewer].
