### Region

United States

### Example URLs

- Single video: https://vl.collab.inc/videos/553891

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

After examining the site in devtools, the video ID after /videos/ in the URL can be used in a GET request to `https://dashboard.collab.inc/api/public_video_library/<VIDEO_ID_HERE>` with what looks like no custom headers. This GET request returns some JSON, which includes a `hls_stream` key which points to a *watermarked* m3u8 video. The m3u8 links look like this: `https://collab-media-assets.s3-us-west-2.amazonaws.com/watermarked_hls/3fefae2f-3d21-4a6b-bb45-3899023ce0cb/5548610291_collab_clips_mpugc_getting_ducks_out_of_garage.m3u8`. Getting the un-watermarked hls stream link is simple: Replace `watermarked_hls` with `hls` in the URL so that the link reads as follows: `https://collab-media-assets.s3-us-west-2.amazonaws.com/hls/3fefae2f-3d21-4a6b-bb45-3899023ce0cb/5548610291_collab_clips_mpugc_getting_ducks_out_of_garage.m3u8`. Then, simply download the hls stream (like yt-dlp has been doing for millenia) and the video has been downloaded!

### 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
