Thanks for that – really helpful.
To follow on – do you know of a good way to smooth out little jumps in the video? The camera was high up, taking the time-lapse, and so got buffetted by the wind from time to time, and though it returned to the “normal” position, and most of the video is fine there are little jumps in the video where I guess the camera has taken one or two frames while it’s off by a fraction of a degree, making the video jump for a fraction of a second.
