You are negotiating with the first viewers
The systems are different, and they change. The part that stays useful: a post is shown to someone, they either give it time or they do not, and that behavior teaches the next decision. Followers are not a guarantee they will see it. Interest is.
So the work is boring on purpose. Clear topic, strong open, a reason to finish, and a pattern the next post can repeat. Hashtags, posting times, and "secret" settings are tie breakers. They do not rescue a video people leave.
