How to Convert Instagram Live Videos to YouTube Shorts Clips

To turn an Instagram Live replay into YouTube Shorts clips, download your live, trim the best parts, size for vertical, and add captions. Vidulk automates this workflow.

Instagram Live to YouTube Shorts Clips - How to Convert

Step 1: Download Your Instagram Live Replay

After your Instagram Live ends, download the replay from Instagram. This gives you a vertical (9:16) video file - ideal for Shorts, but often long and unedited.

Step 2: Understand YouTube Shorts Requirements

Length: Up to 3 minutes
Aspect Ratio: Vertical (9:16) or square (1:1)
Resolution: 1080x1920 for vertical
Captions: YouTube auto-generates captions, but you can upload or edit them

Any video outside these specs won’t be recognized as a Short.

Step 3: Edit and Clip for Highlights

Instagram Lives are usually long and may be shaky. Trim out dead space, intros, or technical glitches. Focus on engaging moments or Q&As. Keeping clips under 60 seconds can boost engagement, but Shorts allow up to 3 minutes.

Step 4: Automate Clipping and Captioning With Vidulk

Vidulk’s free AI clipper app (iOS & Android) streamlines this process. Upload your Instagram Live replay, and the AI scans for the most engaging moments. It exports vertical clips sized for YouTube Shorts (9:16, 1080x1920), with captions burned in - ready for upload. You can review, trim further, or adjust captions before exporting. This saves time and helps ensure your Shorts are punchy and accessible.

Step 5: Upload to YouTube Shorts

Upload your finished clips via the YouTube app or desktop. Double-check that your video is vertical or square and within the 3-minute limit. Add a catchy title, description, and relevant hashtags for better 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.
