Visir is handled by the media route, which reads the site's own rendition list before choosing anything. Visir is one of the smaller integrations here, so the extractor keeps its handling deliberately general rather than assuming a page layout.
The address bar works too. Prefix any Visir URL with tikt.com/:
tikt.com/https://www.example.com/path/to/media
The order of operations
1. Copy the Visir 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 Visir 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 Visir 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.
