Remember this thread where a timelapse was smoothed?
I might be able to add 1 intraframe between exposures, but that comes at a bandwidth price. I was going for the basic illusion of cloud development, taking frames 4 s apart, exposing each for 1/250 s, and running them at 16 fps. A 1 intraframe addition would bring that up to 1/32, which is closer to standard video. Or I could skip any interpolation and take shots every 2 s.
