A one-second video is seldom going to show more than a single photograph. Sure, there's a little motion, but the quality is worse and if you want to stop and take a look you have to pause the video. I'd stick with taking one photo a day.

I know there are counterexamples. But for those things, you'd probably want to take a longer video anyway. What kind of events is a 1-second video the best way to capture, anyway?
