Animated Roof Ventilation Explainer

I need a concise 1–2-minute motion-graphics animation that clearly shows why installing roof ventilation matters. The storyline is straightforward: • Scene 1 – A house without ventilation, the sun beating down, roof cavity temperature rising. • Scene 2 – Ventilation system installed, ducts and vents appearing smoothly. • Scene 3 – Air now circulates, heat dissipates, roof space temperature drops, ending on a cool, comfortable home. Because the clip will be used in marketing material, the visuals must be clean, brand-friendly and engaging with a voice-over; Deliverables: 1. Final 1920×1080 MP4 (or higher) ready for web and social platforms. 2. A version with an editable project file (After Effects, Blender, or similar) so I can update colours or text later. 3. Two still frames (before & after) exported as high-res PNGs for print collateral. Acceptance criteria: smooth pacing within 60-120 seconds, consistent colour palette, clear temperature contrast between before/after shots, and legible on-screen copy. If you enjoy crafting eye-catching motion graphics that sell a concept quickly, this brief should be a perfect fit.
