Rocket Progress Timeline Video

You are an expert video editor and technical director for aerospace launch broadcasts, with deep knowledge of SpaceX production style, camera systems, and mission telemetry overlays.

Generate a complete FFmpeg command-line script (or Adobe Premiere/DaVinci Resolve export preset JSON, depending on {{editing-platform}}) that sequences and composites a full launch video covering:

**Timeline Structure:**
1. Pre-launch montage: time-lapse of {{vehicle-name}} assembly and rollout over {{dev-timeline}} (e.g., "3 years" or "18 months")
2. Vehicle close-ups on pad: distinctive paint scheme—white nosecone, white fuselage, black band with white triangle decal, secondary dark ring lower on body, visible panel lines
3. Onboard camera: nadir-pointing (straight down) view showing nosecone panel detail
4. Launch sequence: T-minus countdown timer, water suppression system active on deck, ignition, tower clearing, long-distance tracker shot
5. Sonic boom moment: beach-angle camera as vehicle goes transonic/supersonic
6. Multi-cam broadcast grid: 9 simultaneous camera feeds in 3×3 layout
7. Live telemetry overlay: mission clock with real 1:1 time progression, Max-Q callout appearing dynamically at appropriate timestamp

**Technical Requirements:**
- Output: 4K 60fps, H.264 or H.265
- Color grading: high-contrast broadcast style, slightly desaturated whites, deep blacks
- Audio: include engine roar, water deluge rumble, and mission control comms loop
- Transitions: hard cuts for pre-launch, smooth crossfades during ascent
- Overlay font: Industry or similar sans-serif, white with 40% black drop shadow
- Clock format: T+ MM:SS, updates every frame (not every second; smooth animation)
- Max-Q indicator: animated label appears at ~70 seconds, fades after 3 seconds

**Constraints:**
- Countdown clock must animate frame-by-frame; no static overlays or jumpy updates
- The 9-camera grid should occupy the full frame, each cell 1280×720 scaled from 4K sources
- Vehicle paint must remain consistent across all pre-launch and pad shots
- Do NOT use generic white rocket stock footage; all references must match the described livery

Provide the full executable command or config file, with inline comments explaining each filter chain, timing offset, and overlay keyframe.
