From one line to a finished story video
A good premise is one line with a problem in it: a lighthouse that keeps being relit by no one. If you can write that, you have enough to start, and the rest is writing, voice and pictures.
Hushline writes the story from your line, picks the best of three drafts before spending anything on video, and films about 60 seconds of it. You can add a genre and a host to steer the tone.
Every Hushline video is made with AI: the story, voice, pictures and video are all generated. $29 for 5 videos, $69 for 15, $149 for 40.

Questions
What makes a good premise?
One character, one problem, one odd detail. "A nurse keeps finding the same call light on in an empty room" works. A whole plot summary is better pasted as a story.
How long is the video?
About 60 seconds, vertical, the shape TikTok, Reels and YouTube Shorts expect.
What does a video cost?
Hushline sells credit packs: $29 for 5 videos, $69 for 15 and $149 for 40. One credit makes one video. There is no subscription and nothing is unlimited.
