When filming video, how long should you shoot a scene? Longer than you think.
Count at least ten seconds for each shot. This makes sure you will have more than enough footage that if later you want to fill more space in the video with footage.
I like to think of it as getting a hair cut. A stylist can always do more the more hair they to work with.
Things will come up editing that you didn’t expect when filming. You’ll find you’ll always want more footage to fill a video, not less.
