How to Turn YouTube Videos into Facebook Reels Clips

To convert a YouTube video into Facebook Reels clips, use Vidulk’s AI Clipper to generate short, vertical, captioned videos sized for Reels - no manual editing required.

YouTube Video to Facebook Reels Clips: How to Convert Easily

Step 1: Prepare Your YouTube Video

Ensure you have rights to the YouTube video you want to clip - use your own uploads or videos you’re licensed to repurpose. Copy the YouTube link or download the video file to your device for upload.

Step 2: Use Vidulk’s AI Clipper App

Open Vidulk (iOS or Android).
Paste the YouTube link or upload your video file.
The AI analyzes the content, finds 5 - 15 of the most engaging moments (for long videos like podcasts, lectures, or vlogs), and turns them into short clips.

Step 3: Format for Facebook Reels

Vidulk automatically converts clips to vertical 9:16 aspect ratio, as recommended for Facebook Reels (1440x2560 resolution preferred).
Clips are captioned by default - important since Facebook Reels ads do not support auto-captioning.
Facebook Reels no longer have strict length or format restrictions, but vertical, short clips work best for engagement.

Step 4: Export and Post to Facebook Reels

Export your finished clips from Vidulk.
Upload the vertical, captioned clips directly to Facebook Reels via the Facebook app or web interface.
Review your clip in the Facebook Reels preview to ensure captions display correctly and the video is framed as intended.

Vidulk's AI clipper (free to start, iOS + Android) finds the best moments in a long video and exports captioned vertical clips sized for the destination.
