UltraVid

UltraVid is a tool for downloading TikTok videos at the highest available quality, without watermarks. It handles the reverse-engineering of TikTok's video delivery pipeline to extract clean source files.

Motivation

Content creators and editors frequently need clean source video from TikTok for compilations, analysis, or archiving. Existing tools were unreliable, ad-heavy, or produced low-quality output. I built UltraVid to be fast, clean, and consistently reliable.

How it works

• Takes a TikTok URL and resolves it to the underlying video asset
• Bypasses watermark injection by targeting the pre-watermark video stream
• Serves the highest bitrate version available from TikTok's CDN
• Simple web interface: paste a link, get a clean download

Technical details

The backend is a Python service that handles URL resolution and video extraction. Nginx sits in front as a reverse proxy and handles static file serving. The frontend is vanilla JavaScript with a minimal UI. The system is designed to be self-hosted and lightweight.
