How to Turn Facebook Live Recordings Into Instagram Reels Clips

To convert a Facebook Live recording into Instagram Reels clips, download your video, reformat it to 9:16 vertical, add captions, and export within Reels specs. Vidulk's AI clipper automates this process.

Facebook Live to Instagram Reels Clips: How to Convert

Step 1: Download Your Facebook Live Recording

After your Facebook Live session ends, download the video from Creator Studio or Meta Business Suite. The file will typically be in a 16:9 (horizontal) or sometimes 9:16 (vertical) aspect ratio. Make sure you have the highest quality version available for editing.

Step 2: Understand Instagram Reels Requirements

Aspect Ratio: 9:16 vertical (1080x1920 pixels recommended; Meta also accepts 1440x2560 for ads)
Max Length: Up to 20 minutes (as of August 2026, using the Reels camera); shorter clips are more engaging
Captions: Instagram can auto-generate captions in-app, but pre-burned captions are recommended for accessibility and engagement

Step 3: Clip, Reframe, and Caption Your Video

You can manually edit your Facebook Live recording using a video editor:

Cut out the best moments (aim for 15-90 seconds per clip for most engagement)
Reframe to 9:16 vertical. Crop or zoom in to focus on the main subject
Add captions, either manually or using a tool that supports burned-in subtitles

This process is time-consuming and requires some editing skills.

Step 4: Automate With Vidulk's AI Clipper

Vidulk (iOS & Android) streamlines this workflow. Paste your Facebook Live video into the app. Vidulk's AI automatically:

Finds the most engaging moments in your long video
Converts clips to vertical 9:16, centered on faces or action
Adds burned-in captions for accessibility
Exports clips sized for Instagram Reels (and other platforms)

This saves hours of manual work and ensures your content fits Instagram's specs.

Step 5: Upload to Instagram Reels

Transfer your exported clips to your phone if needed. Open Instagram, select the Reels tab, and upload your videos. You can add stickers, music, or use Instagram's caption sticker for extra accessibility. Double-check that your video displays correctly in 9:16 format and that captions are legible.

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.
