## Changes from V3

### Architecture
- V3: 1 static frame per scene + ffmpeg zoompan/pulse effects

### Real-Time Animations
- Progress bars: real-time 0→100% fill across frames
- Token counts: incremental counting up to target
- Elapsed time: second-by-second counter
- Text lines: progressive reveal (bash output, code, diff)
- Cursor: frame-level blinking (15f on/off)
- Error: red flash at critical moment
- Success: pulsing green verdict

### Claude Code Realism
- Status bar: ● main, bypass permissions on, context %, agent status
- Tool call cards: Bash(), Write(), Edit() with real syntax
- Agent lifecycle: spawning→running→completing→done
- Multi-agent: 2-3 workers with individual progress bars
- Thought indicator: "Thought for Xs..."
- Real symbols: ● main, ◯ general-purpose, ✓ completed

- Safe margins: 40px on all sides

### Scene Count
- V3: 9 scenes
