Alternatively, "20 RA" could be an encoder’s internal version tag: – of a specific VVC encoder binary.

Here is where the release gets interesting. 720p is considered "HD," but it is lower resolution than the standard 1080p or 4K found on modern discs.

This represents the successor to HEVC (H.265). It offers approximately 30–50% better data compression for the same perceptual quality, making it ideal for maintaining high fidelity in smaller file sizes.

Using the codec, the encoder has managed to crush the file size to a mere 1.2GB for a 90-minute film without introducing macro-blocking. At 720p, the bitrate sits incredibly low (~1800 kbps). Key observations:
