Possibly.
The thing is though for some scientific stuff, it'd be handy to take photos every 30 seconds or so, and then analyse them in "time sections". Sure you could probably just skip 30s at a time in the video, but the picture quality wouldn't be as good.
I'll have to have a look at some of the options this weekend and have a play with them
I guess I could always get a cheap intervalometer to use with the G12...
