A direct 1:1 rip of a Blu-ray (an ISO or BDMV folder) consumes 25GB to 50GB. allows you to shrink that to 4GB to 15GB with near-transparent quality. This is achieved through:

: This feature tracks how often parts of a frame are reused to predict future frames, allowing the encoder to allocate higher quality to segments that remain on screen longer, leading to better overall efficiency.
: This indicates the source of the video. Unlike "WebRip" or "HDTV," a BluRay source provides the highest possible bitrate and detail available to consumers, serving as the "master" for the digital copy.

, it means the video was sourced from a physical Blu-ray disc and compressed using the x264 encoder to create a high-quality digital backup. The Benefits of Using x264 for Blu-ray Rips A standard 1080p Blu-ray disc can hold up to 50GB of data. While this provides "lossless" quality, it is impractical for most home media servers. x264 is the go-to choice for compressing these files for several reasons: Universal Compatibility: Unlike newer formats like HEVC (x265) , x264 files play on virtually any device—including older smart TVs, game consoles, and web browsers—without needing to be "transcoded" (converted on the fly), which saves CPU power. Superior Quality-to-Size Ratio: Compared to older formats like Xvid, x264 provides much better image quality at the same bitrate. It allows a 30GB movie to be shrunk to 8GB–12GB while retaining enough detail that most viewers can't tell the difference. Advanced Compression Techniques: x264 uses sophisticated math to predict motion between frames, reducing the amount of data needed for static scenes while focusing detail where the human eye is most likely to notice it. x264 vs. x265: Which is Better? In recent years, a newer standard called
: x264 uses advanced algorithms like Adaptive Quantization (VAQ) and Psy-RD to maintain visual detail where the human eye is most likely to notice it (e.g., facial features) while more aggressively compressing background areas.
If you see a file labeled Movie.2024.1080p.BluRay.x264 , it has been re-encoded. It is bit-for-bit identical to the disc.
If you see a file named Movie.2024.1080p.BluRay.x264-SCENE.mkv , here is what each part tells you: : The resolution (1920x1080 pixels). BluRay : The source was a physical disc. x264 : The codec used to compress the video.
