Streaks is handled by the media route, which reads the site's own rendition list before choosing anything. Streaks is one of the smaller integrations here, so the extractor keeps its handling deliberately general rather than assuming a page layout.
Either paste a Streaks link above, or put tikt.com/ in front of any Streaks URL in your address bar:
tikt.com/https://www.example.com/path/to/media
What you actually have to do
1. Copy the Streaks link
Use the address bar or the platform's own share button — both give a URL the extractor recognises. Point it at the single item you want, not the page around it.
2. Let it read the renditions
Paste the URL above. The extractor asks Streaks which renditions exist for that item and picks the best progressive one rather than assuming a quality.
3. Save what comes back
The file arrives in the container Streaks served it in, and the extractor does not rebuild it — so what you end up with is what the uploader encoded, for better or worse.
