Kort,
Compose you scene on a tripod (so it stays consistant)  My G6 has an interval minimum of 1 shot every minute (up to 100 total)   

For that IR time lapse I took approximately 30 images (30 minutes) and then created the gif.

30 secs may not be enough to get good motion (from clouds, sun)

It would if you're actually moving  an object I think (since you would be controling the movement)
