AI Heated Round Brush Product Video Using Seedance 2.5

Create a 15-second vertical 9:16 ultra-premium photorealistic CGI beauty-tech product commercial featuring the uploaded heated round styling brush as the strict hero-product reference. Preserve the exact matte-black handle proportions, rose-gold metallic barrel, bristle arrangement, bristle-tip geometry, barrel vents, end cap, digital temperature display, metallic control strip, power/function buttons, power cord, visible FORCOSMO branding, materials and all product proportions throughout every shot; never redesign, recolor, deform, simplify or invent components. Render at 30 fps using a virtual full-frame camera, approximately 70–135 mm equivalent focal lengths, 1/60 s shutter, ISO 100–200, 5200–5600 K white balance and f/5.6–f/7.1, with physically correct subtle motion blur and perfectly stabilized robotic product-camera movement. From 0–2 s, show the complete brush floating diagonally against a seamless warm peach-to-deep-brown gradient, handle below and round barrel above, power cord naturally exiting the base; use approximately 80 mm at f/5.6, three-quarter front/side framing, slow 2–4% dolly-in and gentle clockwise orbit while the product slowly becomes more upright and reveals its digital control face, with a clean vertical metallic highlight traveling across the rose-gold barrel; hard cut at 2 s. From 2–4 s, use a 105–120 mm macro lens at f/6.3–f/7.1 to show the black handle, vertical FORCOSMO branding, digital temperature display and rose-gold control strip extremely close to camera; slowly track vertically along the controls while the digital temperature reading increases through several stable values from a lower setting through the 100s toward approximately 200°C, keeping all numbers crisp and consistent and the function/power buttons visible underneath; illuminate the rose-gold trim with soft warm edge highlights while retaining rich matte blacks, then hard cut at 4 s. From 4–6 s, show the round brush head diagonally with the end cap toward lower-left and barrel extending toward upper-right using approximately 95–105 mm at f/5.6–f/6.3; gradually introduce a controlled orange-red internal heating glow through the vented barrel core, increasing in intensity between the black bristles while maintaining realistic reflective rose-gold metal, matte plastic and individual bristle materials; the effect must communicate thermal technology and never resemble fire, molten metal or uncontrolled sparks; use only a subtle orbit and push-in, then hard cut at 6 s. From 6–8 s, switch to a 120–135 mm extreme macro traveling slowly along individual black bristles, rounded tips, rose-gold vent slots and repeating barrel geometry with a very narrow moving focus plane; introduce a small number of elegant warm golden micro-particles gently drifting between the bristle rows as a premium technology visualization, keeping them sparse and controlled; hard cut at 8 s. From 8–10 s, show two identical copies of the exact same brush floating in a darker black-to-copper environment using approximately 75–85 mm at f/6.3; rotate and reposition both products slowly in zero gravity until they form a clean centered X-shaped arrangement, with one passing naturally behind the other, maintaining identical scale and geometry, warm rose-gold edge lighting and no clipping or collisions; ease the movement into a stable symmetrical X and hard cut at 10 s. From 10–11.9 s, show a close vertical brush-head hero view using approximately 95–105 mm at f/6.3 and animate three to four thin translucent cyan-blue airflow ribbons spiraling smoothly around the barrel in clean helical paths with subtle motion blur, physically traveling around rather than through the bristles and allowing the warm metallic product to contrast against the cool airflow visualization; use only an extremely slow push and tiny orbit, then hard cut around 11.9 s. From 11.9–13 s, show the complete styling brush vertically centered against a nearly black studio background with restrained warm copper light near the bottom, using approximately 80 mm at f/6.3–f/7.1 and a gentle dolly-out that gradually reveals a minimalist angular pedestal entering from below while the power cord hangs naturally downward. From 13–15 s, stabilize the brush perfectly centered above a split geometric pedestal composed of clean light and dark angular surfaces, lock the camera into a symmetrical premium hero composition, retain subtle warm side/rim illumination around the matte-black handle and strong clean rose-gold reflections along the barrel, and hold the image to the end without adding captions, logos or extra graphics. Use clean hard cuts around 2 s, 4 s, 6 s, 8 s, 10 s and 11.9 s. Use a huge warm diffused upper/front-left key, broad soft right fill, controlled negative fill, narrow copper reflections and no clipped highlights. Add restrained futuristic electronic sound design with soft cinematic whooshes on cuts, subtle digital ticks during the temperature animation, a rising thermal tone during the heat reveal, delicate micro-particle textures during the bristle macro, a wider stereo sweep while the two brushes form the X, smooth air sounds synchronized with the cyan spirals and a restrained low-frequency resolve during the final hero shot. Avoid people, hands, hair, salon environments, extra products, random text, captions, UI, watermark, extra logos, product redesign, unstable temperature numbers, changing button layouts, inconsistent or missing bristles, melted materials, distorted barrel geometry, incorrect cord placement, flames, excessive sparks, cartoon particles, thick neon airflow, airflow passing through the physical product, accidental duplication outside the X sequence, collisions, physics jitter, fisheye distortion, handheld shake, fast camera motion, excessive bloom, lens flare, chromatic aberration, oversaturation or unrealistic reflections.
