This is the encoding library used to compress the video. It is the industry standard for balancing file size with visual fidelity.

This tells you the source material. The file was "ripped" or encoded directly from a physical Blu-ray disc, which provides much higher bitrates and better image quality than standard streaming versions.

This denotes the resolution. 1920x1080 pixels is the standard for Full High Definition (FHD), ensuring the vastness of space looks crisp and detailed.

This is the most important part for 3D enthusiasts. In a "Half-SBS" format, the images for the left and right eyes are squashed horizontally and placed side-by-side in a single 1080p frame. When played on a 3D-capable TV or VR headset, the device stretches them back out to create a stereoscopic 3D effect.
