| Filter | Purpose | Recommended Settings for Anime | |--------|---------|--------------------------------| | hqdn3d | Fast spatial‑temporal denoiser, removes grain without smearing edges. | hqdn3d=1.5:1.0:6:4 (luma‑temporal 1.5, chroma‑temporal 1.0, spatial 6/4). | | nlmeans | Non‑local means, great for stubborn blocky patches that survive hqdn3d . | nlmeans=s=3:p=7 (search radius 3, patch size 7). | | deblock | Reduces macro‑blocking after denoising, especially on low‑bitrate frames. | filter=strong:alpha=0.8:beta=0.8 . | | deband | Removes banding that looks like a mosaic in smooth gradients (sky, water). | range=20:iterations=2 . | | nnedi | Edge‑preserving up‑sampler; works better than simple bilinear for anime lines. | nnedi=weights=0.5 (default). | | scale=1920:1080:flags=lanczos | Final high‑quality resize after NNEDI. | lanczos gives sharpness without ringing. | | unsharp | Re‑introduces a touch of crispness after heavy denoise. | luma_amount=0.5 is subtle. |
