Scene notes:

The denser the cloud, the less light the outside areas will allow the light to penetrate through, and this fact is displayed on these towering clouds at sunset. The slower speed is gentler to watch for those who may become motion sickness by watching playback closely. This is an issue for media buyers who have a different experience (after scrutinizing the clip on repeat) than those end-viewers who will only see the clip once. Time-lapse length (at 30 fps):52 seconds and 24 frames.
