Taking a video of clouds at Sunset is very much a pot luck, suck it and see, exercise. As I prefer to start a short while before Sunset there is no guarantee that any colour will appear. I got lucky with my second attempt.
Time lapse taken Wednesday night towards Sunset:
Shot using the LapseIt app on an iPod Touch 5.
One shot every two seconds.
Total 1837 frames processed at 24 fps.
Colours and contrast slightly enhanced in LapseIt and iMovie.
Doing the same thing on a DSLR means having hundreds of individual shots which have to be transferred to a PC or Mac to be made into a video with a suitable program. The LapseIt app for iPhone or iPod Touch does the whole process in one app with the advantage of being able to preview things before making the final video. It is possible to add music in the app but I find it easier to use iMovie on the Mac as I have a large selection of music to choose from on disk.
