How to Turn TikTok LIVE Replays into YouTube Shorts Clips

To convert a TikTok LIVE replay into YouTube Shorts clips, download your replay, select the best moments, and ensure your clips meet Shorts specs. Vidulk's AI clipper can automate this process for you.

TikTok LIVE to YouTube Shorts Clips: How to Convert

1. Download Your TikTok LIVE Replay

Start by downloading your TikTok LIVE replay from the LIVE center in your TikTok app. Only replays you own can be downloaded. Look for engaging segments such as Q&A, reactions, or trending hot takes - these often make the strongest Shorts.

2. Understand YouTube Shorts Specs (as of August 2026)

Maximum length: 3 minutes
Aspect ratio: Vertical (9:16) or Square (1:1)
Resolution: 1080x1920 (9:16 recommended)
Captions: YouTube auto-generates captions for supported languages; you can edit them in YouTube Studio
Any video wider than 1:1 (like 16:9) will be treated as long-form, not as a Short
