What AI does at each step
- Idea to script
- A topic becomes a hook-first script written for a scrolling feed.
- Script to voice
- A clear voiceover that reads well on mute with captions.
- Voice to video
- Vertical b-roll and burned captions, cut to the narration.
- Cover
- Choose the Reel cover before it posts, separately for each feed.
Distribution
One cut, both feeds
- One vertical master posts to Instagram and Facebook.
- Each feed gets its own caption, hashtags, cover, and window.
- You write once and reach both.
Stay original
Keep it yours
- Set your brand voice so every Reel sounds like you.
- Draw scripts only from sources you trust.
- Review each Reel in one queue before it goes out.
Key Takeaways
What to remember
- Reels are Instagram and Facebook's vertical format.
- One master reaches both feeds, each with its own caption.
- Pick the cover deliberately; it is the first thing seen.
- Batch a week in an afternoon and let the schedule feed them.
FAQ
Questions people ask
- What is the best length for a Reel?
- Short. Most strong Reels run between 15 and 45 seconds, long enough for one clear idea and a loop.
- Does the Reel cover matter?
- Yes. Pick it deliberately; the cover is the first thing a scroller sees on your profile grid and in the feed.
- Can one Reel go to both Instagram and Facebook?
- Yes. The same vertical master posts to both, each with its own caption, cover, and posting window.
