   2. Change the purple text
   3. Transform the uploaded video into an ultra-realistic Hollywood-level cinematic VFX sequence.
   4. Preserve the original person exactly. Keep the face, identity, facial features, skin tone, hairstyle, clothing, body proportions, expression, gestures, lip-sync, voice, spoken words, audio pacing, camera framing, and room layout unchanged.
   5. The room must remain the same real room. Do not replace the background. Do not create a fantasy environment. The VFX must happen inside the actual room and interact realistically with the microphone, chair, wall, floor, lighting, furniture, and surrounding objects.
   6. Creative direction: Make the person look like they are controlling a dangerous cinematic force inside the room. The effect can be supernatural, sci-fi, explosive, holographic, reality-bending, portal-based, or energy-based, depending on the scene direction.
   7. The effects must look real, heavy, physical, and expensive. Not playful. Not cartoon. Not sticker-like. Not a simple glowing overlay.
   8. Use cinematic realism: dark contrast, practical light flicker, volumetric dust, shockwave distortion, debris movement, realistic reflections, force-field lensing, heat haze, pressure ripples, camera shake, motion blur, speed ramps, hard light flashes, and powerful sound design.
   9. Color palette: [INSERT COLOR PALETTE, EXAMPLE: white-hot energy core, electric blue plasma, violet edge glow, deep black shadows, cold cyan reflections, realistic room lighting]
   10. Sound design: Keep the original voice clear and unchanged. Add Hollywood trailer sound effects underneath: [INSERT SOUND EFFECT STYLE, EXAMPLE: deep sub-bass rumbles, power surges, thunder impacts, pressure drops, sharp electric cracks, distorted whooshes, glass fractures, metal stress sounds, portal suction, bass drops, final explosion hit].
   11. The pacing must be fast, aggressive, and cinematic. Every beat should escalate.
   12. Timeline VFX direction:
   13. [START TIME] to [END TIME] Script: "[INSERT EXACT SPOKEN LINE]"
   14. Movement: [DESCRIBE THE PERSON'S REAL MOVEMENT DURING THIS MOMENT, EXAMPLE: hands rise in front of chest / arms open wide / right hand reaches toward camera / finger presses forward]
   15. VFX: [DESCRIBE THE MAIN EFFECT. Make it physical and cinematic. Mention how it reacts to the person's movement.]
   16. The effect should interact with the real room. Include details such as: [INSERT ROOM INTERACTION, EXAMPLE: microphone shakes, chair vibrates, wall light flickers, floor catches glow, dust lifts, background bends, nearby objects distort, reflections split]
   17. Camera: [INSERT CAMERA MOVEMENT, EXAMPLE: slow push-in, fast push-out, impact shake, speed ramp, micro-zoom, whip- in, tunnel pull, lens distortion, motion blur, shallow depth of field]
   18. Sound: [INSERT SOUND DESIGN, EXAMPLE: pressure drop, deep bass ignition, electric crackle, thunder hit, distorted whoosh, glass shatter, portal suction, final impact boom]

   Common failure modes

   • The generated scene changes the person, camera, room, product, or timing beyond the requested effect.
   • Fast motion hides face, hand, clothing, text, or continuity errors that become visible when the clip is paused.

   1. Modify the provided prompts and for Phase 3. Phase 2: Use My Prompts Page 3/3 Phase 2: Use My Prompts Page 3/3
   2. Change the purple text
   3. Final quality target: This must look like a premium Hollywood cinematic VFX shot inside the original room.
   4. The effect should feel real because it interacts with the physical space: the microphone reacts, the chair reacts, the wall light flickers, the floor catches glow, dust moves with the shockwaves, nearby objects respond to the force, and the camera reacts to every major impact.
   5. Gesture matching: [START TIME] to [END TIME]: [INSERT MOVEMENT] + [INSERT EFFECT] [START TIME] to [END TIME]: [INSERT MOVEMENT] + [INSERT EFFECT] [START TIME] to [END TIME]: [INSERT MOVEMENT] + [INSERT EFFECT] [START TIME] to [END TIME]: [INSERT MOVEMENT] + [INSERT EFFECT] [START TIME] to [END TIME]: [INSERT MOVEMENT] + [INSERT EFFECT] [START TIME] to [END TIME]: [INSERT MOVEMENT] + [INSERT EFFECT]
   6. Important constraints: Preserve the original person exactly. Do not change the face, identity, clothing, body, hairstyle, expression, voice, lip-sync, speech, or pacing. Do not replace the room. Do not change the script. Do not cover or distort the real face. Keep the original audio timing unchanged. Only add cinematic VFX, lighting, camera movement, particles, distortion, room interaction, holograms, portals, shockwaves, energy effects, and dramatic sound effects.

   Common failure modes

   • The generated scene changes the person, camera, room, product, or timing beyond the requested effect.
   • Fast motion hides face, hand, clothing, text, or continuity errors that become visible when the clip is paused.

   Do not create a fantasy environment

   Use the source inputs to complete this stage and produce a result that can be checked before continuing.

   1. MY EXAMPLE Page 1/4:
   2. Transform the uploaded video into an ultra-realistic Hollywood-level supernatural action VFX sequence.
   3. Preserve the original person exactly. Keep his face, identity, facial features, skin tone, hairstyle, clothing, body proportions, expression, gestures, lip-sync, voice, spoken words, audio pacing, camera framing, and room layout unchanged.
   4. The room must remain the same real room. Do not replace the background. Do not create a fantasy environment. The VFX must happen inside the actual room and interact realistically with the microphone, chair, wall, floor, lighting, and surrounding objects.
   5. Creative direction: Make it feel like the person is controlling a dangerous unstable force that bends gravity, light, pressure, and space inside the room.
   6. The effects must look real, heavy, physical, and expensive. Not playful. Not colorful magic. Not cartoon lightning. Not sticker overlays. Not cheap glowing hands.
   7. Use cinematic realism: dark contrast, practical light flicker, volumetric dust, shockwave distortion, debris movement, realistic reflections, force-field lensing, heat haze, pressure ripples, camera shake, motion blur, speed ramps, hard light flashes, and powerful sound design.

   10. The pacing must be fast, aggressive, and cinematic. Every second should feel like something is escalating.
   11. Timeline VFX direction:
   12. 0s to 1s Script: "Video effects like this"
   13. As his hands rise in front of his chest, the room suddenly loses power and drops into a darker cinematic grade.
   14. A violent white-blue energy core ignites between his hands. It should look like compressed gravity, not a simple aura. Light bends around it. Dust freezes around it. Small pieces of air distortion orbit the core.
   15. His fingers and palms glow from the heat of the energy. The glow must cast real light onto his face, shirt, microphone, chair, wall, and floor.
   16. Camera: Slow push-in toward his hands. Add subtle handheld vibration, lens breathing, and slight background compression.
   17. Sound: Low pressure drop, deep bass ignition, electric crackle, rising power charge.

   Common failure modes

   • The generated scene changes the person, camera, room, product, or timing beyond the requested effect.
   • Fast motion hides face, hand, clothing, text, or continuity errors that become visible when the clip is paused.

   5s to 5.5s Script: "But right now"

   Use the source inputs to complete this stage and produce a result that can be checked before continuing.

   1. MY EXAMPLE Page 2/4:
   2. 1s to 3s Script: "Used to take a lot of time"
   3. As he opens both arms wide, the energy detonates outward.
   4. A massive invisible shockwave blasts across the entire room. The microphone shakes. The chair vibrates. The wall and floor bend with force-field distortion. Dust and small debris lift from the surfaces. Energy cracks tear through the air for a split second.
   5. The blast should follow the direction of his arms, like he is physically ripping the room open.
   6. Add multiple layers of impact: first a silent pressure pull, then a white-blue flash, then a heavy shockwave, then a delayed ripple across the room.
   7. Camera: Fast push-out as his arms open. Add impact shake at the shockwave hit. Add speed ramp from normal speed to aggressive burst, then back to normal.
   8. Sound: Huge trailer boom, thunder crack, deep sub-bass wave, violent air whoosh, metal stress rising sound.
   9. 3s to 4.5s Script: "And editing skills"
   10. As he pulls his hands back inward, the whole blast reverses violently.
   11. All the energy, dust, light cracks, shockwave rings, and debris are sucked back toward his hands and chest. The room stretches inward like gravity is collapsing into him.
   12. Do not use soul fracture. Do not create ghost copies.
   13. Instead, create a gravity-compression event: the air caves inward, the walls appear pulled toward him, the microphone and chair distort toward the center, light streaks reverse direction, and energy rings collapse into a spinning white-hot core.
   14. His hands leave fast blue-white motion trails as they pull inward. The core becomes unstable, brighter, and denser. The pressure around his upper body should look dangerous, like the room is about to implode.
   15. Keep his real face sharp and unchanged. Do not cover the face.
   16. Camera: Aggressive push-in toward his chest. Add rapid micro-zooms, lens distortion, and strong motion blur on the collapsing energy. Add one sharp camera jolt when the core locks.
   17. Sound: Reverse impact suction, turbine-like power surge, distorted whooshes, electric cracks, heavy compression slam.
   18. As his hands release downward and his body resets, the compressed core explodes.
   19. A massive white-blue power pulse erupts from his chest and hands. The whole room flashes. A shockwave hits the walls, floor, microphone, and chair. Light tears across the frame like a physical blast.
   20. The explosion should feel real and dangerous, but the room must remain intact. No destruction of the actual set. Only violent pressure distortion, dust, light, and energy.
   21. After the blast, residual plasma smoke and glowing particles drift through the room for a split second before fading.
   22. Do not cover or distort the real face. Keep the original audio timing unchanged. Only add cinematic aura, gravity distortion, explosions, shockwaves, hologram interface, portal collapse, camera movement, lighting, particles, and dramatic sound effects.

   Common failure modes

   • The generated scene changes the person, camera, room, product, or timing beyond the requested effect.
   • Fast motion hides face, hand, clothing, text, or continuity errors that become visible when the clip is paused.

    7s to 8s Script: "Here's how"

    Use the source inputs to complete this stage and produce a result that can be checked before continuing.

    1. MY EXAMPLE Page 3/4:
    2. Camera: Hard impact shake, slight roll, then quick stabilization as the room returns to normal.
    3. Sound: Massive bass hit, explosive energy release, thunder impact, glassy crack, short cinematic silence after the blast.
    4. 5.5s to 6.7s Script: "You can create this with just a few prompts"
    5. As his right hand reaches toward the camera, make the effect feel huge and close to the viewer.
    6. His hand becomes the anchor point for the next power surge. Blue-white energy wraps around his fingers. Electric arcs jump between fingertips. The closer his hand gets to the lens, the more the image bends.
    7. The room behind him should compress in depth, as if the camera is being pulled into his palm.
    8. A cinematic holographic power interface forms directly in front of his hand, close to the lens. It should look like a real object made from glass, plasma, light, and force-field distortion.
    9. The interface forms readable text:
    10. The text must be embedded inside the hologram, not placed as a flat caption. It should feel three-dimensional, glowing, refracted, and physically present in the room.
    11. The hologram should cast light across his fingers, face, shirt, microphone, wall, and floor. Keep the face visible.
    12. Camera: Dramatic push-in toward his extended hand. Add shallow depth of field, foreground lens distortion, and subtle handheld tension.
    13. Sound: Fast power build, electric surge, glass assembly, hologram ignition, rising trailer tension.
    14. As his hand pulls back and points forward, the hologram locks onto his fingertip.
    15. The interface charges violently. Energy rings spin around the text. The room lights flicker. The microphone, chair, wall, floor, and background appear pulled toward the hologram.
    16. When he presses forward, trigger the biggest cinematic moment.
    17. The hologram overloads and explodes into a massive portal shockwave. The room stretches into a high-speed tunnel of energy, glass shards, lightning streaks, light cracks, and collapsing frame fragments.
    18. Make the transition feel like reality is being ripped open by his fingertip.
    19. The person must remain recognizable and unchanged during the pull. Do not morph his face. Do not change his body.
    20. End with a huge frame-tear collapse into darkness, as if the entire video has been pulled through the portal.
    21. Camera: Fast whip-in toward the hologram on the press. Then rapid tunnel pull, heavy motion blur, violent lens distortion, final impact shake.
    22. Sound: Sharp press impact, electric burst, glass shatter, portal suction, massive cinematic whoosh, deep bass drop, final Hollywood explosion hit.
    23. Preserve the original person exactly. Do not change his face, identity, clothing, body, hairstyle, expression, voice, lip-sync, speech, or pacing. Do not replace the room. Do not change the script.

    Common failure modes

    • The generated scene changes the person, camera, room, product, or timing beyond the requested effect.
    • Fast motion hides face, hand, clothing, text, or continuity errors that become visible when the clip is paused.

    Use the source inputs to complete this stage and produce a result that can be checked before continuing.

    1. MY EXAMPLE Page 4/4:
    2. Final quality target: This must look like a premium Hollywood superhero trailer shot inside the original room.
    3. The effect should feel real because it interacts with the physical space: the microphone shakes, the chair reacts, the wall light flickers, the floor catches glow, dust moves with the shockwaves, and the camera reacts to every major impact.
    4. Gesture matching: 0s to 1s: hands rise and ignite power. 1s to 3s: arms open and blast the room. 3s to 4.5s: hands pull energy back into a gravity core. 4.5s to 5.5s: body resets and detonates the core. 5.5s to 6.7s: right hand reaches toward camera and creates the hologram. 6.7s to 8s: finger press triggers final portal collapse.
    5. Important constraints: Preserve the original person exactly. Do not change his face, identity, clothing, body, hairstyle, expression, voice, lip-sync, speech, or pacing.
