The longest video we've taken is 31/2 minutes. Can't find anything in the manual that tells us the total length of video capability. We are impressed by the stability of the video image even while walking.
Hi Tracy. I think it depends on your memory card. The more expensive ones can do a half hour, I believe. I bought a minimal one (16 mb) and it holds ten minutes of video (so it says, I've never recorded anything longer than 5-6 mins).
