4. Practical AV1 encoding strategies for "extra quality"

• Use a high‑quality source: encode from the least‑processed master (10‑bit, full range, highest resolution).
• Preserve color fidelity: encode in 10‑bit color when target supports it; maintain correct color primaries and transfer.
• Two‑pass or multi‑pass: perform two‑pass encoding to allocate bits optimally across the file for consistent quality.
• Rate control: target higher average bitrates for 4K (example targets: for visually lossless 4K with AV1, 15–30 Mbps is common depending on motion and complexity; for high-detail cinema content, higher may be needed). Use VBR with constrained ceilings.
• Tune for perceptual quality: prefer encoder presets that favor quality over speed (e.g., slower presets in SVT‑AV1, rav1e, libaom‑av1). Enable psychovisual tools where available.
• Use adaptive quantization and content‑aware keyframe intervals: let complexity drive local quality and place keyframes at scene changes.
• Denoise before encoding: apply temporal denoising to reduce codec work on noise; preserve or add film grain in post if desired.
• Film grain synthesis: for movies, consider encoding without grain (lower bitrate), then add modeled grain at playback to preserve perceived texture.
• Tiles and threading: use tiles and multithreading to speed encoding without affecting quality; watch for decoder compatibility limits.
• Use compliant profiles and generate multiple renditions for ABR streaming (4K, 1440p, 1080p, 720p) encoded with quality‑balanced bitrates.

5. Measuring & validating quality

• Generate VMAF scores per rendition and set minimum thresholds per resolution (e.g., 4K target VMAF ≥ 95 for near‑lossless; practical targets vary).
• Run subjective A/B tests on sample audiences or internal reviewers for critical content to validate perceived improvements.
• Monitor rebuffering and startup time tradeoffs; perceptual quality matters only when playback is smooth.

1. Background: AV1 and why it matters

• AV1 is an open, royalty-free video codec designed for higher compression efficiency than H.264/HEVC/VVC for the same visual quality. It’s widely adopted by major streaming platforms and browser vendors.
• For "extra quality," AV1’s efficiency allows delivering higher perceptual quality at a given bitrate or the same quality at lower bitrates—useful for 4K/HD streaming and constrained networks.

3. The Illusion of "Extra Quality"

It is important to note that the "extra quality" label on these sites is often misleading. Unlike legitimate platforms that use advanced compression algorithms (like HEVC/H.265) to deliver true high definition smoothly, unregulated sites often just re-upload bloated files. A file labeled "1080p Extra Quality" might actually be an upscaled 720p video that takes up massive amounts of storage space on your device without actually looking better.
