That sounds like a useful approach but isn’t something I have any experience with.  Can you go into more detail on how you prepared the file with the decimated vectors and then what the process is to plot it?

In the past, I have saved decimated vectors of the signal to a file and used that to recreate a long, static waterfall plot for debug of satellite passes.

I would like to save a waterfall plot (spectrograph) to a video file so that I can share it and cut out portions of interest for presentation.  Has anyone found a way to directly save the output to an MP4 or some other video format? 


I have been using a screen recorder but that takes a good time of time and the process ends up requiring 2 to 4 different programs by the time you record, edit and have your file ready for presentation.  It would be a time savings to save it directly.
