A 4K video lasting just 15 minutes results in a very large file size. For a high-quality, uncompressed 4K stream, 15 minutes could require of storage. Even with standard compression, a 4K video at 40 Mbps (typical for Blu-ray quality) would be roughly 4.5 GB for 15 minutes. The 7z format offers high compression ratios that can handle these sizes well. The .7z container likely contains one or more .mp4 video files. The .009 extension is part of a split archive, meaning all related parts ( .001 , .002 , etc.) are required for a successful extraction. Including the label -No PW- suggests a file without password protection. However, if encryption is needed, 7‑Zip can also produce AES‑256 encrypted archives.
When a file is split, the software appends a sequential numeric suffix to the extension. For example: Archive.7z.001 Archive.7z.002 Archive.7z.009 J SS Taso 015 4K 15mins -No PW- Mp4 7z 009

The first part of the code, "J SS Taso 015," has no clear public record, but each part strongly suggests it is a content identifier, likely a code for a specific video episode or segment:
