How to Turn Instagram Live Videos into Facebook Reels Clips

To turn your Instagram Live into Facebook Reels clips, download the Live, trim key moments, resize for 9:16, and add captions. Vidulk’s AI Clipper can automate this process for you.

Instagram Live to Facebook Reels Clips: How to Create

Step 1: Download Your Instagram Live Video

After ending your Instagram Live, download the full video from your Instagram account. This file will usually be in a vertical (9:16) format, which is ideal for Reels. Save the video to your device for editing.

Step 2: Understand Facebook Reels Clip Requirements

Aspect Ratio: 9:16 (vertical) is recommended for full-screen display.
Resolution: 1440x2560 pixels is optimal, but 1080x1920 is also accepted.
Length: No strict max length since June 2025; any video posts as a Reel.
Captions: Optional but recommended for accessibility and engagement. Facebook Reels ads do not support auto-captioning, so add captions manually or with a tool.

Step 3: Clip, Trim, and Caption Key Moments

Instagram Lives are often lengthy and unedited. For engaging Reels, select highlights or moments that stand alone. Trim the video tightly to remove pauses or off-topic sections. Add captions to maximize retention, as many users watch without sound.

Step 4: Automate with Vidulk’s AI Clipper

Vidulk's AI Clipper (iOS and Android) streamlines this process:

Upload or paste your full Instagram Live video.
The AI analyzes and identifies the best moments to turn into short, shareable clips.
Exports vertical (9:16) clips sized for Facebook Reels (1080x1920 or 1440x2560), with captions auto-generated and burned in.
Review and export your clips, ready to upload to Facebook Reels.

Step 5: Export and Upload to Facebook Reels

Once your clips are ready, export them in the recommended format and resolution. Open Facebook, start a new Reel, and upload your optimized, captioned clip. Double-check for correct aspect ratio and caption visibility before publishing.

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.
