First of all I wish you a happy new year.
I had lovely holidays, went completely off the grid and had the opportunity to rest; I believe this replenished energy will be fully needed in this final stage.
I had to re-undo some work in order to go back to having opencv as a git submodule, and this raised some yet unresolved issue, surely they will prove easy enough to overcome. I worked a bit with a webcam, and there is not much difference from working with a recorded video.
Tomorrow, I will document myself on the shutter issue, and will decide with the group what to do depending on my findings.
