The extractor recognises 3 distinct Ndr URL shapes, which is why the link already sitting in your address bar normally works without you hunting for a share button. Whatever it resolves to comes back with its container intact. Ndr also carries live output, and a stream still in progress has no final file to give you yet. Ndr is handled by the media route, which reads the site's own rendition list before choosing anything. Ndr publishes real audio renditions, so an audio request there is a copy rather than a re-encode.
The address bar works too. Prefix any Ndr URL with tikt.com/:
tikt.com/https://www.example.com/path/to/media
From the Ndr link to a saved file
1. Copy the Ndr 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 Ndr 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 Ndr 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.
