Emily Lakdawalla, who writes the great blog at the Planetary Society, posted an nice animation she created from 5 images she processed from Mars Express of moving clouds.
I was interested to see what After Effects could do with those 5 frames i.e. something longer with more detail in 1080p, so I used some Revision FX and Red Giant plugins to work with the frames.
Added some quick music and here is the result. Her post is here about her animation process with the original five frames.
