Precise Cord Demo Video

I need a 15–30-second product demo that shows a simple cord-and-bead mechanism behaving exactly as it would in real life. One cord runs behind an imaginary wearer’s neck; three beads sit on that cord—one fixed at center, the other two free to slide naturally with gravity when the cord is lifted or tilted.

The emphasis is on accuracy and repeatability rather than artistic flair. To make the motion unmistakably clear, the shoot should alternate between a clean wide shot of the full setup and tight close-ups that capture each bead’s movement. I would like this filmed against a natural setting background (for example, outdoors or on a neutral wooden surface) so viewers can instantly see the product in a real-world context without distractions.

Deliverables
• Finished 15–30 s video file (export in a common format such as MP4, MOV, or AVI).
• Smooth cuts that highlight the center bead remaining fixed while the side beads glide.
• Consistent lighting and framing in both the wide and close-up angles.

Acceptance criteria
• Side beads must travel freely and return calmly when the cord rests, with no jerky edits masking their path.
• Center bead may not shift more than an imperceptible fraction of a millimeter throughout the clip.
• Background remains uncluttered and clearly natural; nothing competes with the cord system for attention.

If you shoot with a tripod, macro lens, or slow-motion capability, please do—anything that helps convey the mechanics faithfully. I will provide prompt feedback on draft cuts so we can lock the final version quickly.
