# Layout Animation System - Implementation Summary
## ✅ What Was Built
### Three Core Components
#### 1. **LayoutTransition** (`components/transitions/LayoutTransition/`)
Scene-to-scene layout transitions with 5 variants:
- ✅ `crossfade` - Smooth opacity blend
- ✅ `slide_horizontal` - Push left, slide right
- ✅ `slide_vertical` - Push up, slide from bottom
- ✅ `cube_rotate` - 3D rotation effect
- ✅ `parallax_push` - Depth layers effect
**Motion tokens used:** `ease_out_expo`, `ease_in_out_quart`, `ease_out_quint`, `medium`, `slow`
#### 2. **LayoutEntrance** (`components/animations/LayoutEntrance/`)
Universal entrance wrapper with 9 variants:
- ✅ `none` - Instant (no animation)
- ✅ `fade_in` - Simple fade
- ✅ `fade_slide_up` - Fade + slide up
- ✅ `scale_in_soft` - Subtle scale 0.95→1.0
- ✅ `scale_in_pop` - Bounce scale with spring
- ✅ `slide_in_left` - Slide from left
- ✅ `slide_in_right` - Slide from right
- ✅ `blur_in` - Fade from blur
- ✅ `zoom_in` - Explosive zoom 0→100%
**Motion tokens used:** `ease_out`, `ease_out_expo`, `ease_out_back`, `smooth` spring, `normal`, `medium`, `slow`
#### 3. **PanelCascade** (`components/animations/PanelCascade/`)
Staggered panel animations with 7 variants:
- ✅ `from_edges` - Slide from nearest edge (intelligent spatial)
- ✅ `from_center` - Radial scale from center
- ✅ `bounce_in` - Spring bounce
- ✅ `sequential_left` - Left→right reading order
- ✅ `sequential_right` - Right→left reverse
- ✅ `sequential_top` - Top→bottom vertical
- ✅ `wave` - Diagonal wave pattern
**Motion tokens used:** `ease_out_expo`, `ease_out_back`, `bouncy` spring, `fast`, `medium`

## 🎯 Token-First Architecture
### Design System Integration
**All animations reference motion tokens:**
```typescript
// Example from LayoutTransition template
const DURATION_MEDIUM = [[ motion.duration.medium.frames_30fps ]];
const easeOutExpo = [[ motion.easing.ease_out_expo.curve ]];
const opacity = interpolate(
relativeFrame,
[start, start + DURATION_MEDIUM],
[0, 1],
{
easing: Easing.bezier(...easeOutExpo)
}
);
```
**Benefits:**
- ✅ Change `motion.duration.medium` → updates all components
- ✅ Platform optimization (TikTok vs. cinematic timing)
- ✅ Consistent feel across entire video
- ✅ No hardcoded magic numbers
---
## 📐 Pydantic Native
### Schema Structure
All components follow Pydantic-native patterns:
```python
# schema.py
class LayoutEntranceProps(BaseModel):
"""Properties for LayoutEntrance component."""
content: Any = Field(description="Layout or component to animate in")
entrance_type: str | None = Field("fade_in", description="Animation style")
entrance_delay: float | None = Field(0.0, description="Delay (seconds)")
start_time: float = Field(description="When to show (seconds)")
duration: float | None = Field(5.0, description="Duration (seconds)")
class Config:
extra = "forbid"
# Metadata for auto-discovery
METADATA = ComponentMetadata(
name="LayoutEntrance",
description="Universal entrance animation wrapper",
category="animation"
)
```
**Validation:**
- ✅ Type safety with Pydantic
- ✅ Auto-discovery via `METADATA`
- ✅ MCP_SCHEMA for tool registration
- ✅ Composition builder integration

## 🤖 AI-Ready Tool Documentation
### Example from LayoutTransition
```python
async def remotion_add_layout_transition(
first_content: str,
second_content: str,
transition_type: str = "crossfade",
# ...
) -> str:
"""
Add LayoutTransition for animated scene-to-scene transitions.
Example transition_type values and their effects:
- crossfade: Smooth opacity blend (professional, subtle)
- slide_horizontal: Push left, slide in right (sequential content)
- cube_rotate: 3D rotation effect (dramatic, attention-grabbing)
Example first_content Grid layout:
{
"type": "Grid",
"config": {
"layout": "3x3",
"items": [
{"type": "CodeBlock", "config": {"code": "Panel 1"}}
]
}
}
Args:
first_content: JSON component (format: {"type": "...", "config": {...}})
transition_type: One of: crossfade, slide_horizontal, ... (default: "crossfade")
```
**AI-Friendly Features:**
- ✅ Explicit JSON format examples in docstrings
- ✅ Variant descriptions with use cases
- ✅ Concrete examples for each parameter
- ✅ Clear parameter type annotations

## 🎨 Motion Token Usage Summary
| Component | Duration Tokens | Easing Tokens | Spring Tokens |
|-----------|----------------|---------------|---------------|
| LayoutTransition | `medium` (0.5s), `slow` (0.7s) | `ease_out_expo`, `ease_in_out_quart`, `ease_out_quint` | — |
| LayoutEntrance | `normal` (0.35s), `medium` (0.5s), `slow` (0.7s) | `ease_out`, `ease_out_expo`, `ease_out_back` | `smooth` |
| PanelCascade | `fast` (0.2s), `medium` (0.5s) | `ease_out_expo`, `ease_out_back` | `bouncy` |
### Token Coverage

- ✅ `fast` (PanelCascade)
- ✅ `normal` (LayoutEntrance)
- ✅ `medium` (all components)
- ✅ `slow` (LayoutTransition, LayoutEntrance)
**Used 5 of 15 easing curves:**
- ✅ `ease_out`
- ✅ `ease_out_expo`
- ✅ `ease_out_back`
- ✅ `ease_in_out_quart`
- ✅ `ease_out_quint`
**Used 2 of 7 spring configs:**
- ✅ `smooth` (default)
- ✅ `bouncy` (playful)

## 🧪 Testing & Validation
### Pydantic Validation
```bash
✅ LayoutEntrance schema valid
✅ PanelCascade schema valid
✅ METADATA exports working
✅ MCP_SCHEMA present
```
### Component Registration

## 🎯 Next Steps (From Original Roadmap)
### Not Yet Implemented
4. **FocusSwap** - Animate focus between panels (FocusStrip, PiP, Mosaic)
5. **VerticalReveal** - Platform-specific Shorts/Reels animations
6. **DialogueChoreography** - Speaker-driven panel animations
7. **GridMorph** - Morph between grid configurations
8. **OverTheShoulderMotion** - Camera-like motion simulation
9. **HUDPulse** - Micro-interactions for HUD overlays
10. **TimelineScroll** - Animated timeline reveals
All would follow the same **token-first + Pydantic-native** architecture.
