How to Make 20-Second AI Reels in Flow

Hunting for a Reel idea you can actually produce tonight? This share walks through the moonlit dreamscape and autumn fantasy niche: AI-generated vertical footage you can post on Instagram, with monetization and affiliate work as the longer game.

Two 10-second clips become one 20-second video, and that is all the setup this needs.

Tutorial

1. Set up one social media account to post from. Ask ChatGPT for a name and the other profile details if you are stuck on what to call it.
2. Open Flow, pick 10s, then pick 9:16. The 10s setting fixes each clip's length, and 9:16 gives you the full-screen vertical frame Reels uses.
3. Generate the clip and wait for it to finish.
4. Edit at least 2 videos into one 20-second video. Two 10-second clips joined end to end get you there.

Wrapping Up

You now have a vertical 20-second AI video and a visual niche to hang it on. Post it as a Reel, then keep the moonlit and autumn look consistent across the next ones, since that consistency is what the source is counting on for the feed and for monetization and affiliate work later.
