One thing I have found with taking video of rowing is that a lot of the time it is difficult to judge exactly what difference to the boat speed changing technique/rates can make. You can review your strokcoach data back but its difficult to visualise what you were doing at the time so I wanted to find a way of overlaying the data ontop of the video so you can actually see both the rowing, and data from the strokecoach, at the same time.
After quite a lot of experimentation I managed to find a working combination which can result in videos like this:
iPhone (running the NK Speedcoach app) – To capture the data from rowing
Camera (see my previous post on possible cameras)
PC software – Dashware
– Your video editor of choice (to edit the Dashware output) – Mine is Powerdirector
1) Collect the data
Mount the camera and attach your iPhone running the NK app to the boat, personally I have an iDry which I have put velcro on the back to secure it to the boat, this means the phone is dry and safe and can be easily removed.
2) Transfer the data to the PC
Copy the video and iPhone data to your PC (i usually order the videos intheir own folders per date). To get the data off the iPhone go into the app, select history, select the workout that you are after, click the specific workout (I usually have recorded the workout as “just go”, click “export CSV” then you can download the data from the iPhone within itunes
3) Adding the gauges in Dashware
Before you start with Dashware you need to add the NK gauge and the profile for the iPhone data into dashware, these can be found here. Under Windows 7 the folders that they need to be added to are under “libraries” -> “Documents” -> “Dashware” -> Add the NK gauge to “Gauges” and the profile to “dataprofiles”
EDIT – Apparently the link now doesn’t work to the dashware forums 😦 the most recent Dashware actually includes rowing gauge and the dataprofile for TCX, so if you export the .tcx this should work natively with Dashware and the .tcx file exported from the app
EDIT 2 – Linked is the dataprofile that works with the .csv file that the speedcoach app exports, if you add that to the dashware dataprofiles folder then Dashware should work nice with the .csv files from the app
Load up Dashware and it will ask you to select a new video, select the video you have taken and wait for it to load. Once it is loaded click on the plus symbol in the data file and add your data file from the iphone you saved earlier, Dashware should automatically come up with the “speedcoach for iPhone” profile
Now all you have to do is change the gauges to the one you prefer (usually the NK gauge and possibly the map), synchronise the data with the video using the synchronisation tab and then file -> create video (note: not sure if its the same for everyone but I find the output video type Mpeg2 High quility, large file size to be the best and works bets with Powerdirector)
4) Editing/adding to the video
As mentioned, I use powerdirector just to trim the video down from the usual 1-2 hour videos to the important things, plus in the video editor you can add more information like a readout from GoogleEarth/other camera footage etc, as an example:
I have filmed myself running through this process so if it helps to watch it being done (and helps clarify points I have missed/any questions you may have)
Hope this helps! Best of luck creating your own videos!
