• Images: Up to 9 reference images (mood boards, product shots, brand assets) • Videos: Up to 3 video clips (existing footage, motion references) • Audio: Up to 3 audio files (trending sounds, voiceover, SFX) • Text: Full prompt with timing, camera, lighting, sound • Max Assets: 12 total combined • Output: 4-15 seconds, 720p video with synchronized audio • Reference Syntax: @material[name] to reference uploaded assets ---

• 0-2s: The gate. If 50%+ bounce here, the video dies. If 90% stay, the algorithm promotes. • 2-5s: Hook confirmation. Brain decides: worth my time or not. • 5-15s: Engagement peak. Emotional beats, reveals, payoffs land here. • 15s+: Retention cliff. Most viral videos are under 15 seconds. Videos with 80%+ completion get 2-3x algorithmic reach. Your hook determines everything. ---

| Technique | Mechanism | Prompt Template | |---|---|---| | Physics Break | Objects defy gravity, water flows up, time reverses | "Open with [object] defying physics — floating upward, sliding in reverse, freezing mid-air. Camera steady, treating impossible action as mundane. First 0.8s shows normal expectation, 0.8-2s breaks it. No music, only ambient sound emphasizing the wrongness." | | Scale Warp | Familiar object at impossible size | "Extreme wide shot: [tiny object — coin, key, pen] scaled to building size in landscape. Human figure provides scale reference at base. Drone-style camera slowly pushing forward. Overcast lighting, photorealistic. Viewer spends 2s processing scale." | | Color Bomb | Grayscale world gets sudden saturation | "Scene begins fully desaturated — gray, lifeless, muted. At 1.2s, single element ignites with saturated color [neon pink/electric blue/gold]. Color bleeds outward across frame over 0.8s. Hard bass hit synced to color moment." |

| Technique | Mechanism | Prompt Template | |---|---|---| | Obscured Subject | Camera hides the reveal | "Tight framing shows only hands working on [something]. Close-up of concentrated facial expression. Sounds of creation — cutting, assembling, clicking. Camera never shows the full object. At 2s, slight pull-back hints at shape but doesn't reveal. Viewer must keep watching." | | Reaction Before Action | Show the response, hide the cause | "Open on person's face — eyes widen, jaw drops, hand covers mouth. Camera captures pure shock reaction for 2s. No context, no environment shown. Sound: gasp, then silence. The question 'what are they looking at?' forces continued viewing." | | Countdown Tension | Visual timer creates urgency | "Bold text '3' appears center-frame with bass hit. Cut to new angle, '2' with rising synth. Cut again, '1' with tension peak. Frame holds on black for 0.5s. The reveal never comes in the hook — it's downstream. Camera movements accelerate with countdown." |
