is the release group code for Amazon . In the warez/scene release taxonomy, a tag like AMZN signifies that the source of the video file is Amazon’s streaming infrastructure (Amazon Prime Video). This means the video was ripped directly from Amazon’s servers, ensuring the best possible bitrate, 4K or 1080p resolution, and Dolby audio before compression. An AMZN web-dl (Web Download) is often superior to a WEBRip (which might come from a screen recorder).
