Bloomberg serves its media as FLV, and that is exactly what you keep. The container is passed through rather than rebuilt, so there is no generation loss between what Bloomberg stored and what ends up in your downloads folder. Bloomberg is handled by the media route, which reads the site's own rendition list before choosing anything. No credentials are involved anywhere in this path — neither yours nor ours.
Either paste a Bloomberg link above, or put tikt.com/ in front of any Bloomberg URL in your address bar:
tikt.com/https://www.example.com/path/to/media
What you actually have to do
1. Copy the Bloomberg 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 Bloomberg 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 Bloomberg 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.
