With Bypass Linear Light Conversion off, Exposure decoded and re-encoded with the piecewise sRGB curve. After Effects 2026 renders (sRGB working space, 32 bpc) of Offset 0.0005 / 0.002 / 0.02 / 0.1 on black measure 8 / 15 / 43 / 90, which a pure 2.2 power predicts (8.06 / 15.13 / 43.08 / 89.54) and the sRGB curve does not (1.65 / 6.59 / 38.68 / 89.04). The effect now uses its own 2.2 power curve on the CPU and in the GPU kernel; the shared colour functions and other effects are unchanged. As before, the conversion applies whatever the working space, also a linearised one. Negative values go through both curves mirrored (input was clamped at 0 before), so defaults are an identity for 32-bpc values and a negative Offset darkens past black without NaN. New test against the AE values; existing Exposure tests still hold. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Effects are the deepest single area of After Effects. This page separates the four questions that a single "306 of 306" hides: does each effect exist, does it run fast, does it look like After Effects', and does the preset library exist. The per-effect catalogue is the generated effects.md; the overall numbers are in target-app-parity.md.
Summary
| Question | Value | Kind |
|---|---|---|
| Effects present | 306 registered, 3,017 parameters; all of After Effects' effects by name (298 at the M9.11 count) plus Obsolete and our own | Measured: registry, effects.md. After Effects 26.5's Plug-ins/Effects holds 306 .plugin bundles in 231 entries (one bundle can hold several effects, so this is a cross-check, not a match) |
| Parameter names, order, popups, units, defaults | aligned in M9.12 | Agent-checked against After Effects' documentation, not against a live dump |
| On the GPU | 280 (92%) | Measured: registry flags; GPU vs CPU agreement tested per effect |
| 32-bit float, no clamping | 306 | Measured: registry flags |
| Rendered output matches After Effects | unmeasured | Only Tint is checked against After Effects renders (four solids, within 1/255). effectcraft_effects::fidelity::compare_frames exists for the corpus (fidelity/README.md); simulation effects are pinned by golden hashes of our own output (M13.27) |
| Animation presets | 54 original presets (8 text-animator, 23 Transitions, 23 Backgrounds) against After Effects' 621 .ffx presets |
Measured: crates/engine/presets/text_animators.json, crates/engine/presets/transitions.json, crates/engine/presets/backgrounds.json; the After Effects Presets folder |
| 26.x additions | Curl Noise (26.3) present (#463 open); effect colour labels (26.5) present in Effect Controls only, not in the Timeline; the rebuilt Effect Controls (26.5) missing | Release notes |
Breadth ≈ 85% (presets weigh in; the effects themselves are ≈ 100%). Ready ≈ 40%: until a corpus compares renders, each effect is assumed to differ somewhere, and users keep confirming it.
By category (from effects.md)
| Category | Effects | On the GPU | Known differences or bugs |
|---|---|---|---|
| 3D Channel | 8 | 8 | Cryptomatte selection can't be set in the UI and the GPU path is slow (#473; quoted names with commas fixed); multi-layer EXR decode shared (#474 open: f16 storage and cache sizing remain) |

| Channel | 13 | 13 | — |
| Color Correction | 40 | 40 | Tint, Tritone and Black & White (sliders and Tint) match After Effects 2026 renders (Rec. 601 luminance); Tint has Swap Colors (#963); ACES 2.0 / OCIO 2.5 (26.5); Apply Color LUT (#514) and 32-bpc blending (#494) are closed |

Third-party bundles in After Effects (Cineware, Mocha AE) are out of scope; Keylight is implemented under a generic name ("Key Light").
Estimate
≈ 70–130 h: a fidelity corpus case per effect at default and one non-default setting, compared with After Effects renders, and the fixes they turn up (40–80 h, most of it parallel, but every reference render needs After Effects on the owner's Mac); an original preset library covering After Effects' preset categories (Behaviors, Shapes, Synthetics, Text, Image effects remain; Backgrounds and Transitions exist) 15–35 h; the open effect bugs 10–20 h. Moving Fractal and the analysis effects to the GPU is performance, not parity.
