How to Turn Instagram Live Videos into TikTok Clips

To convert Instagram Live videos into TikTok-ready clips, you need to trim, caption, and size your content for TikTok’s vertical format. Vidulk’s AI Clipper automates this, making the process fast and easy.

Instagram Live to TikTok Clips - Turn Lives into Vertical

Step 1: Download Your Instagram Live Video

After your Instagram Live ends, download the full video from your Instagram account. This gives you a vertical-format source file, but it may be long, unedited, and shaky.

Step 2: Understand TikTok’s Clip Requirements

Length: TikTok allows uploads up to 60 minutes, but short, punchy clips (15 - 60 seconds) usually perform best.
Aspect Ratio: 9:16 vertical is recommended. TikTok also supports 1:1 and 16:9, but vertical fills the screen.
Resolution: 1080x1920 pixels is standard for 9:16 clips.
Captions: TikTok offers auto-captions, but editing or adding your own before upload helps accuracy.

Step 3: Manually Edit or Use Vidulk’s AI Clipper

Manual Workflow: Use editing software to trim the best moments, crop to 9:16 if needed, and add captions. Export at 1080x1920 for best results.
With Vidulk: Upload your downloaded Instagram Live to Vidulk’s free AI Clipper (iOS or Android). The AI finds highlight moments, generates short vertical clips, and adds accurate captions sized for TikTok. You can review and export the clips directly to your phone.

Step 4: Upload to TikTok

Transfer your finished vertical clips to TikTok. On the TikTok edit screen, you can toggle auto-captions, apply final filters, and add hashtags before posting. Always preview your video to ensure it meets TikTok’s specs and looks sharp.

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.
