I create my own short form content (Web Series, short films, skits). I am looking to launch a new series, but I am wondering about the best length for overall popularity and profit. I have done alright with 8 minute videos for action and five minute videos for comedy. I am in the pre-production stage for an action series, sitcom, and child led sitcom (Think Fred). What would be the best length times for each series? I am most interested in maximizing my earning potential and rank via audience retention.
