Thank you this is what I was looking for. And I also am on a mac, and found this perfectly program called "Gawker".Cinema quality movies is at 24 fps , I would think a frame every 5 to 10 minutes would run smooth if your doin a video of a week or longer. Could possibly even stretch it out to ever30 minutes or hour. But if you want a long vid of a day in life , snap a shot every minute or 2.... you use software to combine photos to a time lapse video. Or you might have an expensive programable camera that has a time lapse feature..
