### Region

_No response_

### Example URLs

**NSFW** https://www.adultempire.com/4738510/tiffany-watsons-1st-dp-porn-videos.html

### Provide a description that is worded well enough to be understood

**I am not asking to support downloading the pay-walled videos** since that would be a violation of the copyright/DRM content (Up to my understandings).

However the page offers some trailers (like the one in the example URL I shared) that can be accessed without an account and up to my understanding should be downloadable without infringing copyright/DRM.

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
