Hi,
The ODF export is now part of the software: File > Export to Spreadsheet.
(by the way, you may want to upgrade to 0.8.7 which was released a few hours ago
)
However, the line length is not exported in these yet. Currently, it only exports key images titles, path tracking points coordinates, and chronometers time values.
So, currently to export a stride length automatically, it's a little bit complicated. You would have to create a path tracking (right click a point and do "Track point") and then move the video forward, adjust the tracking until you get to the end of the stride, where you'd finish the tracking.
Then you export that to spreadsheet, and you can get the coordinates of start and end points, and do the maths in the spreadsheet to get the length.
[Technical note]
If you know XSLT (or someone else reading this thread) you may modify the actual stylesheet to make it export the line length. The stylesheets are stored in the /xslt directory in the Program Files, you don't need to rebuild the program to change them. They take a .KVA XML stream as input, and transform it in the corresponding files depending on the option choosen in the menu (ODF, Excel, XHTML, text).
If anyone is interested in contributing in this area, I can provide more details.

EDIT :
Line length has now been integrated into the Spreadsheet export as of version 0.8.8.
A sample export to XHTML can be seen here.
