How to Turn TikTok LIVE Replays into Snapchat Spotlight Clips

Convert your TikTok LIVE replays into Snapchat Spotlight-ready clips with the right sizing, captions, and automation using Vidulk’s AI Clipper.

TikTok LIVE to Snapchat Spotlight Clips: How to Convert

Download Your TikTok LIVE Replay

Start by downloading your TikTok LIVE replay from the LIVE center in the TikTok app. This gives you access to your full, vertical video, which is ideal for creating highlight clips.

Identify the Best Moments for Snapchat Spotlight

Look for engaging Q&A exchanges, strong reactions, or standout hot takes - these segments tend to perform best as short clips.
Keep in mind Snapchat Spotlight supports videos up to five minutes, but shorter, punchy clips often get more engagement.

Automate Clip Creation with Vidulk’s AI Clipper

Open Vidulk’s free app (iOS or Android) and upload your TikTok LIVE replay.
The AI automatically scans your video, identifies the best moments, and generates vertical clips sized for Snapchat Spotlight (9:16 aspect ratio, commonly 1080x1920 resolution).
Vidulk adds burned-in captions directly onto the video, since Snapchat Spotlight does not support SRT uploads or auto-captioning for organic posts.

Export and Upload to Snapchat Spotlight

Download your finished, captioned vertical clips from Vidulk.
Open Snapchat and use the Spotlight upload feature to add your video. Double-check that the video remains vertical and the captions are visible.
If you want to add or adjust captions further, use Snapchat’s in-app Creative Tools before publishing.

Tips for Maximizing Spotlight Performance

Keep clips concise and attention-grabbing within the first few seconds.
Ensure audio quality is clear, as Snap requires videos with sound.
Avoid using still images or horizontal content; Spotlight favors vertical video only.

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.
