Chat GPT gave me this, so it’s probably mostly bs. 
Let me know what you think and if anything can be improved…
Edit: I took each of these for a spin and these actually seem like pretty reasonable settings! I’m sure there’s something that can be improved but I think this is a good starting point.
Edit: Removed “NTSC Color Saturation” and “NTSC Brightness” because we really don’t need to touch those.
| Parameter | Composite (baseline) | Composite (Notch Filter) | Best-Case Composite (Trinitron + good comb filter) | S-Video (separate Y/C) | RGB / Component (perfect) |
|---|---|---|---|---|---|
| NTSC Artifacting (0.00 → 5.00, 1.00 = composite baseline) | ~1.0 (visible dot crawl & shimmer) | ~0.7–0.8 (some crawl remains) | ~0.3–0.5 (strong comb filter kills most) | 0.0 (none) | 0.0 (none) |
| NTSC Fringing (0.00 → 5.00) | ~1.0 (false color edges) | ~0.7–0.8 (partially suppressed) | ~0.3–0.5 (greatly reduced) | 0.0 (none) | 0.0 (none) |
| NTSC Resolution Scaling (0.20 → 2.50, higher = sharper luma) | ~1.0 (soft, smeared) | ~1.1–1.2 (slightly sharper, but muted by notch) | ~1.3–1.5 (sharper, though not S-Video clean) | ~1.8–2.0 (sharp, stable) | 2.5 (max sharpness) |
| Chroma Scaling / Bleeding (2-phase) (0.50 → 4.00, higher = less bleed) | ~0.7–1.0 (lots of bleed) | ~1.5–2.0 (notch reduces some bleed) | ~2.5–3.0 (greatly reduced bleed) | ~3.8–4.0 (very clean) | 4.0 (no bleed) |
| Chroma Scaling / Bleeding (3-phase) (0.20 → 2.25, neutral = 1.0) | ~0.5–0.7 (heavy bleed) | ~0.8–1.0 (moderate bleed) | ~1.2–1.5 (reduced bleed) | ~1.8–2.0 (clean) | 2.25 (no bleed) |
