I've only ever processed OSC data when playing with WinJupos, so I'm presuming things would be different with a mono camera. I would think it would take into account each filter's data and calculate for the combined filters 4 min duration. Maybe you would have to enter the start and finish time for each filter's duration and WinJupos does the rest. I'm sure someone out there will have a better understanding of the procedure than me and explain it to you.
