When downloading from Twitter, rather than redirecting to a clean .mp4, it just redirects to a 403 unauthorized page from video.twimg.com. ?tag=[2 digit number] is appended to the .mp4 file in the path. Removing it returns the clean .mp4 file for download on twimg.com again. Audio conversion and muted videos are unaffected, only videos with sound are affected by this.
reproduction steps
Paste any Tweet link that has a video attached
Download with auto
Get a 403 error, page simply reads "Unauthorized"
Remove ?tag= parameter from the URL
Get a clean .mp4 stream once more
