How to Turn Your Kick Stream into LinkedIn Clips

To create LinkedIn-ready clips from your Kick stream, export your VOD or clip, convert to vertical format, and add captions. Vidulk’s AI clipper automates this process for you.

Kick stream to LinkedIn Clips: How to Create Vertical

Step 1: Export Your Kick Stream or Clip

Start by exporting your Kick stream as a video file. Kick allows you to download your past broadcasts (VODs) or specific clips. LinkedIn accepts video files up to 15 minutes long, but for best engagement, keep your clips short and focused.

Step 2: Reframe to Vertical Format for LinkedIn

LinkedIn supports a range of aspect ratios, including 9:16 (vertical), 4:5, 1:1 (square), and 16:9 (landscape). For mobile-friendly vertical clips, use 9:16 (1080x1920 pixels).
Use a video editor or automation tool to crop and resize your Kick footage to your chosen aspect ratio. Vidulk’s AI clipper can automatically convert horizontal streams to vertical clips sized for platforms like LinkedIn.

Step 3: Add Captions for Accessibility

Most LinkedIn viewers watch videos muted, so captions are essential for engagement and accessibility.
Vidulk’s AI clipper generates accurate, synced captions for each clip. Alternatively, you can enable auto-captions during LinkedIn upload (may take time to appear after posting).

Step 4: Automate the Workflow with Vidulk

Vidulk’s AI clipper (iOS and Android) streamlines the process:

Paste your Kick VOD or clip link into the app.
The AI finds the best moments and exports them as short, vertical clips with captions, sized for LinkedIn’s requirements.
Download the finished clip and upload directly to LinkedIn.
