The MOS increase (≈ 1.2 points) exceeded the threshold commonly reported as just noticeable difference (JND) for streaming video, confirming that the technical gains were indeed perceived by the audience. The minority of participants who preferred SQ cited latency concerns, underscoring the need for adaptive bitrate ladders that can fallback to lower‑resolution streams on constrained networks.

| Step | Tool | Parameters | |------|------|------------| | Pre‑processing | FFmpeg 6.0 | Denoising (nlmeans), colour‑space conversion to BT.2020. | | Resolution Scaling | VapourSynth + RIFE 4.0 (AI‑based frame‑interpolation) | Upscaled to 3840 × 2160 (4K). | | Codec | libaom‑av1 (AV1) | Two‑pass, CRF 23 (first pass: stats, second pass: bitrate allocation). | | Audio | Opus 2.0 (48 kHz, 96 kbps) | Normalised to –23 LUFS. | | Container | MP4 (ISO‑BMFF) | Fast‑start flag for progressive streaming. | | Quality Check | VMAF 4.4 (HD and 4K profiles) | Calculated against ProRes reference. |

A secondary test set employed H.265/HEVC with a CRF of 25 to compare codec efficiency. vegamoviestovinlandsagas01complete1to extra quality

| Codec / Config | Avg. VMAF | ΔVMAF vs. SQ | Avg. PSNR (dB) | Avg. SSIM | |----------------|-----------|--------------|----------------|-----------| | SQ (Baseline) | 71.2 | — | 33.8 | 0.912 | | HEVC (CRF 25) | 77.9 | +6.7 | 36.4 | 0.937 | | AV1 (CRF 23, 2‑pass) | 83.5 | +12.3 | 38.7 | 0.954 | | AV1 (CRF 25, 1‑pass) | 80.1 | +8.9 | 37.5 | 0.945 |

Key Observation: The two‑pass AV1 configuration achieved the highest VMAF uplift (12.3 points) while maintaining a modest bitrate increase (from 3 Mbps to 7 Mbps). The MOS increase (≈ 1

Context:
In Assassin’s Creed Valhalla, the "Vinland Saga" is a story mode where players assume control of Leif Erikson, navigating Norse exploration, conflict, and diplomacy in 11th-century North America. It includes key historical figures (Harald Hardrada, Hvitserk) and challenges like managing alliances, resources, and battles. Harald Hardrada’s Arrival :
