Twitter Video Downloader -Without API Limit-

Hello Freelancers! We have an already built Twitter Video Downloader website (PHP script), but we recently ran into a problem after making the script online and many users are requesting the script. The problem is Twitter API is throwing an error "Rate Limit Exceeded" after a certain number of requests that's been made. The downloader is currently using Twitter API and we are not liking the fact that it is limited. We want a PHP script that grabs a Twitter Video (multiple formats) and doesn't rely on Twitter API *OR* doesn't have request limits.
