Most releases still use h264 (AVC) or h265 (HEVC). This file uses , officially known as VVC (Versatile Video Coding), finalized in 2020.
VVC is the successor to H.265 (HEVC). It was finalized in 2020 with the goal of being roughly 50% more efficient than its predecessor.
This deep dive breaks down exactly what this specific file string means, why the technology behind it matters, and how it represents the future of media consumption. Decoding the Filename: Piece by Piece
Video often steals the spotlight, but the audio track is equally important to the viewing experience. The filename lists USAC as its audio codec. USAC stands for Unified Speech and Audio Coding. It is an audio compression standard developed by the MPEG group, designed to handle both music and speech with remarkable efficiency at very low bitrates (typically between 12 and 64 kbit/s).
No silver bullet. The “20 RA” profile strips all metadata (no ReplayGain, no chapter markers in audio). VVC decoding remains computationally heavy – a low-power ARM device (e.g., Raspberry Pi 4) cannot decode 720p VVC in real time without stuttering. Additionally, some Shrek enthusiasts argue that the theatrical audio mix (AC-3 at 384 kbps) has a “warmer” low-end for the opening “All Star” sequence. USAC at 20 kbps sacrifices sub-80 Hz bass extension slightly. shrek 2001 720p bluray h266 vvc usac 20 ra
The dragon chase sequence and the Duloc tournament feature rapid camera panning and chaotic particle physics (fire, dust, debris). These sequences easily break weak compression passes, leading to macroblocking.
The keyword is far from random. It signals a deliberate, cutting-edge encode philosophy: respect the source resolution, leverage generational leaps in video compression, and treat audio with perceptually transparent, dialog-first efficiency. As bandwidth caps tighten and storage media remain finite, expect these descriptors to move from obscure forum posts to mainstream release standards. After all, if it works for Shrek’s swamp, it can work for anything.
Just as the video codec is futuristic, so is the audio. is the successor to AAC (Advanced Audio Coding).
In the vast, swampy ecosystem of digital media archiving, a peculiar yet powerful filename has begun circulating among codec enthusiasts, Plex power users, and data hoarders: Most releases still use h264 (AVC) or h265 (HEVC)

Indicates a vertical resolution of 720 lines (1280×720 pixels). This is considered an HD-ready resolution, modest by today’s 4K standards, but practical for testing or bandwidth-efficient storage.
Why would an encoder use USAC for a movie like Shrek , which features a full orchestral score by Harry Gregson-Williams alongside dialogue and sound effects? The answer is precision. USAC uses a hybrid approach: it employs a CELP (Code-Excited Linear Prediction) coding tool for speech segments and a MDCT -based transform coding tool for music and complex audio. It can dynamically switch between these tools in real-time based on the audio content. This allows the encoder to preserve the clarity of Eddie Murphy’s rapid-fire jokes as Donkey and the full dynamic range of the film’s soundtrack without wasting bits.

The fact that this file is encoded with H.266 VVC, a relatively newer video compression standard, suggests that it's a fairly modern encoding, aiming to provide a good balance between video quality and file size.
While Shrek is a digital render, the Blu-ray master retains a specific layer of fine detail and simulated lighting bloom that older codecs tend to turn into flat, muddy gradients.
Here is a deep dive into the technology powering this unique release and why it matters for the future of digital preservation. Deconstructing the Release Tag
This is the centerpiece of the entire filename. h266 and VVC (Versatile Video Coding) refer to the same thing: the most advanced international video compression standard in existence. Finalized in July 2020 by the Joint Video Experts Team (JVET), it was designed to be the successor to the widely used H.265 (HEVC).
