This is a pretty good size for storing videos. You could keep a good amount of video in full HD video and sound if your device supports it. I'm no film maker but I do on occasion capture video of my 2 year old doing funny things. I would say it would hold at least an hour of straight solid video. Now if you were going to film lengthy sports events or similar, I would look for no less than 64GB. But for the average film shooter, this is fine.
