How to Turn Podcast Episodes into LinkedIn Clips

To convert a podcast episode into LinkedIn clips, extract short, vertical, captioned moments sized for LinkedIn and automate the process using Vidulk’s AI Clipper.

Podcast Episode to LinkedIn Clips: How to Convert and Automate

Step 1: Choose Your Source and Identify Key Moments

Start with your podcast episode - either as a video file or audio plus a visualizer. The best LinkedIn clips highlight a hot take, a story, a laugh, or a practical tip. Aim for 30-60 seconds per clip, with the guest’s name visible on screen. This keeps your content engaging and easy to consume for LinkedIn users.

Step 2: Meet LinkedIn’s Video Specs

Length: Up to 15 minutes (30-60 seconds recommended for engagement)
Aspect Ratio: Any from 1:2.4 to 2.4:1 (vertical 9:16 and 4:5 work well)
Resolution: 256x144 up to 4096x2304 pixels (1080x1920 is ideal for 9:16 vertical)
Captions: LinkedIn can auto-generate captions, or you can upload your own for clarity and accessibility

Always ensure your clips are clear, well-lit, and have captions enabled.

Step 3: Use Vidulk’s AI Clipper for Fast, Automated Editing

Vidulk's AI Clipper (available on iOS and Android) streamlines this workflow. Paste your podcast video link or upload the file. The AI scans the episode, automatically detecting the best moments - such as highlights, tips, or laughs - and extracts them as short clips.

Clips are sized vertically and captioned for LinkedIn
Export options include vertical 9:16 and 4:5 to match LinkedIn’s accepted aspect ratios
Guest names and on-screen text can be retained for context

This automation saves time and ensures clips are ready for immediate upload to LinkedIn.

Step 4: Upload and Caption on LinkedIn

After exporting your clips from Vidulk, upload them to LinkedIn. Toggle on LinkedIn’s auto-caption feature for additional accessibility, or use the captions already baked into your video. Double-check video quality and aspect ratio before posting to ensure the best presentation.

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.
