Podcast episode to Facebook Reels Clips: How to Create

Step 1: Identify the Best Podcast Moments

Effective Facebook Reels clips from podcasts typically feature hot takes, engaging stories, laughs, or actionable tips. Aim for 30-60 second segments that grab attention quickly. If your podcast is audio-only, consider adding a simple visualizer or static background for video export.

Step 2: Format for Facebook Reels Specs

Aspect ratio: 9:16 vertical is recommended for full-screen viewing.
Resolution: 1440x2560 is optimal, but 1080x1920 is also acceptable.
Length: No strict limit as of June 2025, but shorter clips (30-60s) perform best for engagement.
Captions: Strongly recommended, as auto-captioning is not supported for Facebook Reels ads. Always include visible, accurate captions for accessibility and retention.
Guest name: Display on screen to add context and credibility.

Step 3: Automate with Vidulk’s AI Clipper

Vidulk’s free AI clipper app (iOS & Android) streamlines this workflow:

Paste your podcast video (or audio with a visualizer) into the app.
The AI automatically detects the most engaging moments, such as laughs, tips, or stories.
Vidulk exports short, vertical clips (9:16) with captions and optional guest name overlays, sized for Facebook Reels.
Export your ready-to-post clips directly to your device, with no manual editing required.

Step 4: Post to Facebook Reels

Upload your finished clips to Facebook. Since June 2025, all video formats post as Reels, but vertical 9:16 is still best for mobile viewers. Add descriptive titles and hashtags to maximize reach.

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.
