Hi all, new here, but I have a very specific problem.
I capture video from an ultrasound device at work. The ultrasound measures a wave form that is displayed across the screen, this is then put through some software that measures the size / area of the waveform.
The problem. Our old ultrasound displayed the wave form sweeping from furthest right on the screen so that the newest signal was always on the furthest right of the screen and everything to the left was previous signals. This was fine as it allows us to set a region on the right for the software to measure the wave.
Our new machine sweeps the waveform across the screen, thus new waveforms can appear anywhere on the screen, this makes it impossible to set a region for the software to measure. Im hoping this makes sense, but in a simple sense, the old machiine 'streamed' measures in from the right, the new machines loops measures across the screen.
What I would like to do is to re-edit or re-capture (Im not sure what the technical name would be) by setting a area say 300px by 100px and then have it capture in one place on the screen for one frame, then capture X pixels to the left in the next frame, then again X pixels to the left in the 3rd frame and so on. In my simplistic mind I 'think' this will result in a small box of video where new waves will always appear. I also have to preserve frame no. as the wave measures have to match up with other measures of the video.
I keep swapping between thinking this is incredibly difficult and actually sounds quite simple... famous last words!
If anyone has any ideas it would be very much appreciated! I have no experience in programming capture software, but I can work most things out if given a starting point and some instructions.
Thanks for reading
