How to Turn Kick Streams into Instagram Reels Clips

To share highlights from your Kick stream on Instagram Reels, you need to convert, reframe, and caption your video to fit Instagram's specs. Vidulk automates this process for you.

Kick Stream to Instagram Reels Clips: How to Convert

Step 1: Export Your Kick Stream or Clip

Start by exporting your Kick stream or selecting a specific Kick clip (10 - 180 seconds). Most creators download the VOD or use Kick’s clip feature. Ensure your file is in a standard video format like MP4 for compatibility.

Step 2: Convert to Vertical (9:16) Format

Instagram Reels works best with full-screen vertical (9:16) videos. If your stream was in landscape, you’ll need to crop or reframe the video. Vidulk’s AI clipper automatically detects and reframes the main action for vertical output, so you don’t have to edit manually.

Step 3: Add Captions for Muted Viewing

Most Reels viewers watch without sound. Captions boost engagement and accessibility.
Vidulk auto-generates captions and burns them into your clip.
You can also use Instagram’s in-app Captions sticker if you prefer to add captions after upload.

Step 4: Match Instagram Reels Specs

Length: Up to 20 minutes (as of August 2026; previously 3 minutes max).
Aspect ratio: 9:16 (recommended), 1080x1920 resolution standard.
Export from Vidulk in the correct format for direct upload to Instagram Reels.

Step 5: Automate with Vidulk

Vidulk’s AI clipper (iOS and Android) finds the most engaging moments from your Kick stream, reframes them to vertical, adds captions, and exports ready-to-post Reels clips in minutes. Just upload your Kick video, select Instagram Reels as your destination, and let Vidulk do the rest.
