Apparently humor in USA sitcoms is so complex that the audience needs help when to laugh.
So there’s an operator using a keyboard to add laughter, or there’s an man/woman instructing a life audience when to laugh/ooohhh/clap or whatever.
Make a short movie (20-30 seconds) and tell us when it’s so funny we’re supposed to laugh. Add some crescendo. Tell us to roll over laughing at the end.
Use your own laugh (record it on your phone) or use free samples online. Mix it and add some footage or images to it.
Use any tools you like – we’re not going to be prescriptive.
Ha ha ha ha ha …
