I'm trying to create a movie and then have a TTL signal be sent at a specific moment during the movie (e.g. when the filmed person says "welcome"). Is there any way I can embed a TTL in a movie? If not, perhaps I can create the movie so that I would want the TTL sent at a specific time (say at 10s after the movie begins). Is there any way a TTL can be sent after a specified period of time?

Thanks!
