Waiting for the clouds to depart I filled in the time with 45 minutes taking 121 frames for a short video. Individual photos are 20 secs, ISO 10,000, Canon 6D, Samyang 14mm f2.8. No noise reduction, 2 second interval between shots. The video was produced using the GPL freeware Virtual dub, 20 frames per second, and a little sharpness/brightness/contrast/curves applied.
The video is only standard def because I get one HD upload per week on my free vimeo account (and I blew it uploading a video that looked horrible because of the codec I initially used).

I am pretty happy with it, just wish it was a bit longer.
Thanks for looking.
