Nowcanal is handled by the media route, which reads the site's own rendition list before choosing anything. Nowcanal is one of the smaller integrations here, so the extractor keeps its handling deliberately general rather than assuming a page layout.
Either paste a Nowcanal link above, or put tikt.com/ in front of any Nowcanal URL in your address bar:
tikt.com/https://www.example.com/path/to/media
The whole process
1. Copy the Nowcanal 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 Nowcanal 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 Nowcanal 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.
