Problem: the built-in animation preset library had no Behaviors category (gap 7: 54 presets against After Effects' 621). Fix: 22 original Behaviors presets in crates/engine/presets/behaviors.json: Soft Wiggle, Shake, Float, Sway, Orbit, Figure Eight, Bouncing Ball, Drift Right, Drift Diagonal, Pendulum, Wobble, Spin Slow, Spin Fast, Pulse, Heartbeat, Breathe, Rubber Band, Jitter Scale, Blink, Strobe, Flicker, Fade Pulse. Each puts a time-based expression on one transform property or opacity (no effects), built on the property's own value so it keeps running for the layer's whole duration. Listed under * Animation Presets > Behaviors. Sidecar, ATTRIBUTION.md, gaps.md row 7 and parity docs updated. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

Effects parity
Last reviewed: 2026-10-12 · Last updated: 2026-10-12 · Change: minor (effect colour labels; earlier change: parameter count and closed issue references re-audited against

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 | No effect is compared with an After Effects render yet. 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 | 76 original presets (8 text-animator, 23 Transitions, 23 Backgrounds, 22 Behaviors) against After Effects' 621 .ffx presets |
Measured: crates/engine/presets/text_animators.json, crates/engine/presets/transitions.json, crates/engine/presets/backgrounds.json, crates/engine/presets/behaviors.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) |
| Audio | 13 | 0 | CPU by design (applied in the mixdown) |
| Blur & Sharpen | 16 | 15 | Gaussian Blur interaction and output to be measured first (fidelity/ae-2026-acceptance.md) |
| Channel | 13 | 13 | — |
| Color Correction | 40 | 40 | Tint has Swap Colors (#963); ACES 2.0 / OCIO 2.5 (26.5); Apply Color LUT (#514) and 32-bpc blending (#494) are closed |
| Distort | 39 | 35 | Liquify has no viewer brush; #303 (Mesh Warp drag) and #534 (CC Power Pin Unstretch) are closed |
| Expression Controls | 9 | 9 | — |
| Generate | 26 | 25 | Fractal on the CPU (needs f64); #526 (Reset) and #536 (Write-on marks) are closed |
| Immersive Video | 12 | 12 | — |
| Keying | 12 | 12 | Key Cleaner approximated; #533 (wire-removal Frame Offset) is closed |
| Matte | 6 | 4 | Mocha shape reads our documented JSON, not Mocha's format |
| Noise & Grain | 13 | 12 | Curl Noise (#463); Match Grain on the CPU |
| Obsolete | 9 | 9 | — |
| Paint | 1 | 0 | Tablet pressure not read (hardware-parity.md) |
| Perspective | 10 | 9 | Chromatic Aberrations pan/tilt crash (#580) |
| Simulation | 18 | 18 | Particle Playground lacks Particle Exploder, text particles, ephemeral mapper; CC Particle World camera fixed (#397) |
| Stylize | 25 | 25 | Motion Tile output size (#369) |
| Text | 2 | 2 | — |
| Time | 8 | 8 | #535 (Pixel Motion Blur, Vector Detail) is closed |
| Transition | 17 | 17 | — |
| Utility | 9 | 7 | — |
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 (Shapes, Synthetics, Text, Image effects remain; Backgrounds, Behaviors 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.
