Create a 15-second native 9:16 vertical selfie-style UGC review in a cozy modern living room with warm natural window light. The entire video must remain portrait 9:16, composed specifically for mobile viewing with no landscape crop, letterboxing, or squeezed widescreen composition. Use realistic skin texture, mild natural handheld phone movement, casual framing, and an authentic “showing a friend my new speaker” feeling. Use @Image1 as the absolute product reference for the Marshall speaker. Use @Image2 as the presenter’s identity reference: preserve her recognizable face, long softly waved brown hair, body proportions, beige satin slip dress, and natural understated styling. Preserve the @Image1 speaker exactly in every shot: one wide rectangular black speaker with softly rounded edges, black pebbled leather-like exterior, dark woven front grille, raised gold Marshall script logo centered on the grille, slim brushed-gold strip along the lower front with the small physical “EST. 1962” marking, short black feet, and a recessed top control panel with its visible gold controls. Keep its proportions, grille texture, black-and-gold palette, logo shape and placement, lower strip, feet, and top controls consistent. Do not invent a carrying handle, display screen, colored lights, exposed drivers, extra buttons, extra speakers, changing logos, unseen ports, or a different cabinet design. Preserve the physical Marshall and “EST. 1962” markings; never mirror, misspell, replace, or distort them. 0-3 seconds — vertical front-camera medium close-up. Place the @Image2 presenter in the upper half of the portrait frame and the @Image1 speaker securely on a console beside and slightly below her, keeping its complete front visible without cropping either side. She looks into the lens, gestures toward it, and says with an impressed smile: “Okay, this might be the best-looking thing in my living room.” 3-6 seconds — hard cut to a vertical handheld product close-up. Keep the full speaker readable while one small natural tilt reveals the pebbled black exterior, woven grille, gold Marshall script, lower gold strip, and recessed top controls. Her hand lightly traces one cabinet edge without covering the logo. She says: “The black texture and gold details are so good.” 6-8 seconds — hard cut to a slightly overhead vertical three-quarter close-up. Show the recessed top control area and front grille together. Her anatomically correct hand makes one deliberate press or adjustment to one control already visible in @Image1; do not add, move, or redesign any controls. A quiet mechanical click is heard. She says: “Okay, listen to this.” 8-12 seconds — uninterrupted music demonstration with no dialogue. Immediately after the control action, the speaker audibly plays a clean, energetic original pop-rock song at comfortable room volume: punchy live-style drums, warm electric bass, bright rhythmic electric guitar, and a confident female singer delivering the original hook, “Turn it up, let the good days roll.” The lyric is sung once only. The track must be newly composed for this video and must not imitate, quote, sample, or resemble any existing copyrighted recording, artist, melody, or lyrics. Keep the source-faithful speaker large in the lower half of the frame while the presenter remains behind it, naturally nodding to the beat and smiling with a genuine first-listen reaction. Let the song remain clearly audible and foregrounded for the full four seconds; do not cover it with speech. 12-15 seconds — hard cut to a close vertical product-and-presenter composition. The same original song continues more softly underneath. Keep the complete speaker front and real Marshall logo readable while the presenter looks back into the lens and gives a small approving laugh: “Yeah, that fills the room. I’m obsessed.” Hold the final portrait frame steady on her reaction and the speaker. Keep all spoken dialogue verbatim and in this exact order, with natural conversational English delivery, realistic pauses, synchronized mouth movement, and gestures aligned to each line. The audio sequence is essential: clear creator speech from 0-8 seconds, one control click, a clearly audible original sung pop-rock excerpt from 8-12 seconds with absolutely no talking over it, then the music lowers beneath the final spoken reaction from 12-15 seconds. Preserve natural room acoustics so the song convincingly originates from the physical @Image1 speaker rather than sounding like unrelated soundtrack music. Do not imitate or reproduce any copyrighted song. No voice-over, captions, subtitles, interface overlays, borders, watermarks, price claims, measured loudness claims, sound-quality specifications, power specifications, connectivity claims, battery claims, waterproof claims, or call to action. Use only purposeful hard cuts; no morphing, whip pans, speed ramps, crash zooms, camera orbits, or glossy commercial moves. Maintain native 9:16 portrait framing, stable @Image2 identity, accurate hands, one consistent source-faithful @Image1 speaker, realistic contact, and clear product visibility through the final frame.
