: The video resolution (1280 x 720 pixels), providing High Definition quality.
: The name of the "release group" (PSA Risks) known for creating highly compressed, high-quality encodes.
: Refers to the color depth; 10-bit encoding allows for over a billion colors, reducing "banding" in gradients (like skies or shadows) compared to standard 8-bit files.
: The video compression standard (High Efficiency Video Coding). It allows for high visual quality at significantly smaller file sizes than the older x264 standard.
