Not arguing semantics but it's telling that the amount is measured in terms of photography (stops). If it really only works for photos then whether one camera has 4 stops and the other 8 stops it's a moot point. I'm far more a results kinda guy not believing specs too much. In my experience I've never seen IS really do a lot for video, but I'm always ready to change my mind based on real results.It doesn't matter what the terminology is.
We can call them "stops" or "pops" or "jelly drops".
If a higher number of pops or jelly drops equals more stabilization of your frame then the technology is going to have an effect on stills or motion pictures. I see less stabilization in my videos with less of them.
