Facebook Live to Facebook Reels Clips: How to Create Vertical

Step 1: Download Your Facebook Live Recording

After your Facebook Live ends, access Creator Studio or Meta Business Suite. Locate the video, choose 'Download', and save the file to your device. Facebook Live videos are usually in landscape (16:9) or sometimes vertical (9:16).

Step 2: Understand Facebook Reels Specs (2025-2026)

Recommended aspect ratio: 9:16 (vertical, full-screen)
Resolution: 1440x2560 (preferred), 1080x1920 also accepted
No length or format restrictions since June 2025 (landscape and square accepted, but vertical is best)
Captions: Optional but recommended; Facebook Reels ads do not support auto-captioning

Step 3: Clip, Resize, and Caption Your Video

Manually, you would need to:

Import your Facebook Live video into editing software
Select highlight moments
Crop or reframe each segment to 9:16 vertical
Add captions manually (for accessibility and engagement)
Export each clip at 1440x2560 or 1080x1920 resolution

Tips for Posting Facebook Live Clips as Reels
