Recording of the running graph

Hi, 
I would like to record the output of the running graph to the file.
The input source I use is a video camera, so it is important to record the
whole video shown in the output window, not only save the graph.  How can
I do this? I couldn't find any "writing to a file" option in the output
module. Are you planning to add this kind of function to Gephex in the
near future? If not, what kind of changes and where in the software I
shoud do I order to record the video?

Thanks,
Liisa Helle
