YouTube to Facebook Reels: paste a link, get the reels

Since June 2025, every video posted on Facebook is shared as a reel, and reels are how Facebook shows your videos to people who don't follow you. Your YouTube videos already have the moments; on Facebook they need to be vertical, short enough to watch through and captioned, since many people scroll with the sound off.

One video gives you many: up to one reel for every 2 minutes of video, so a 30-minute video gives up to 15 and an hour or more up to 30. That's a reel a day for a month from one upload.

Since March 2026, Meta has said it puts original content first in Facebook Feed and Reels and shows unoriginal content less. Content you filmed or produced is original, so reels cut from your own YouTube videos are exactly what Facebook wants more of, and the cheapest reels you'll ever make, since the filming is done.

Clips of someone else's video are another matter. Meta counts minor edits to another creator's content, like inserting captions or changing the speed, as unoriginal, and a campaign's permission lets you post a clip without making it original. If you clip for pay, add your own on-screen take or don't count on Facebook's reach. The details are in Facebook's unoriginal content policy.

• Vertical. Meta's tips say 9:16 helps a reel feel immersive. Every Clyper clip is 1080 × 1920.
• A story or a payoff. Meta says great reels have a beginning, middle and end, or a strong hook or payoff. Clyper cuts each clip from the line that hooks to the one that lands, and scores the hook.
• Captions on the video, for people watching without sound: every word, burned in, above the text Facebook shows at the bottom.
• At least 10 seconds if it's to earn. Shorter reels don't qualify for Content Monetization. Clyper's run 20 to 60 seconds, and you can extend either end by up to 15 seconds.
• A plain post caption. Meta says captions with no links, few capital letters and no more than 5 hashtags do best. Check yours with the character counter.

Every clip is 9:16 at 1080 × 1920, so it posts as it is everywhere. If you post reels on Instagram, you can share each to Facebook as you post it, or upload the file to each app yourself. See YouTube to Instagram Reels, YouTube to TikTok and how to cross-post short videos.

Watch time decides most of it: post the highest-scored reel first, give it a day, then post the next. Check why a reel isn't being distributed in your professional dashboard. Everything Meta has said about recommendations is in how to get more views on Facebook Reels, and what reels pay in how much Facebook pays.
