How to turn long videos into Facebook Reels

To turn long videos into Facebook Reels, cut complete moments to vertical 9:16, add burned-in captions, and post them from your Page. Facebook's Reels audience often skews older than Instagram's and responds to clear, practical and conversational clips, so pick moments for that audience rather than reposting whatever trended elsewhere.

Pick clips for the Facebook audience
Advice, explainers, stories and opinions that start a discussion tend to travel on Facebook because they get shared and commented on. Look for moments where a speaker makes a clear point people will want to agree or argue with.
Cut the clips with AutoClip
Upload the full recording, or paste a link to a video you own. AutoClip transcribes it, scores self-contained moments and returns a shortlist of clips, already captioned and reframed. Choose 9:16 for Reels. The run costs one Clip Minute per minute of source video, and re-running the same video within 7 days to try different settings is free.

Review before you export
Read each clip's first three seconds as a stranger would. If the hook lands late, trim the start; if a word is wrong, fix it in the transcript and the captions follow. Drop any clip that needs the rest of the episode to make sense.
Reuse your Instagram Reels, carefully
If you already post Reels on Instagram, Meta lets you share them to Facebook too. That's a fast start, but watch which clips actually get shared on Facebook and lean into that kind of moment instead of mirroring Instagram exactly.
Check the current length limit
Facebook's maximum Reel length has changed several times. Check it in the Reels composer before you export, and keep clips well under it either way.
Cut complete, discussion-worthy moments to 9:16 with captions and let Facebook's own engagement tell you which kind to make more of. AutoClip gives you the shortlist from one upload.
