How to Turn Instagram Live Videos Into Snapchat Spotlight Clips

To convert Instagram Live videos into Snapchat Spotlight clips, trim and caption vertical moments under 5 minutes, matching Snapchat’s specs. Vidulk’s AI Clipper automates this process for you.

Instagram Live to Snapchat Spotlight Clips: How to Convert

Step 1: Download and Prepare Your Instagram Live Video

After your Instagram Live ends, download the full replay from your Instagram app or archive. The video will already be in vertical (9:16) format, but these streams are often long and may include shaky or off-topic sections.

Download from your Instagram profile after the live ends.
Review the footage for the best moments.

Step 2: Use Vidulk to Automatically Clip, Trim, and Caption

Vidulk’s AI Clipper (available for iOS and Android) helps you quickly turn long Instagram Live videos into short, vertical clips ready for Snapchat Spotlight. Here’s how:

Upload or paste your Instagram Live video into Vidulk.
The AI scans the video, finds the most engaging moments, and creates short clips.
Clips are automatically trimmed, sized to 9:16 vertical, and can be exported with burned-in captions.

This saves you from manually scrubbing through hours of footage or editing captions frame by frame.

Step 3: Match Snapchat Spotlight Requirements

Snapchat Spotlight clips must meet specific requirements:

Length: Up to 5 minutes per video (as of August 2026).
Aspect Ratio: Strictly 9:16 vertical video.
Resolution: 1080x1920 pixels is widely recommended, though Snapchat hasn’t published official specs for organic Spotlight uploads.
Captions: Snapchat does not support SRT or auto-caption uploads for Spotlight. Use burned-in captions (as Vidulk provides) for accessibility and engagement.

Step 4: Export and Upload to Snapchat Spotlight

Once your clips are ready:

Export your finished video from Vidulk in MP4 format.
Transfer the video to your mobile device if needed.
Open Snapchat, tap the Spotlight icon, and upload your video.
Optionally, use Snapchat’s in-app Creative Tools to add stickers, text, or effects.

Always review your clip to ensure it meets Snapchat’s community guidelines and technical requirements before publishing.

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.
