Contest DualCam PIP App Promo Video (AI video)

budget US$ 20.00 for the video. I need a 9:16 portrait video, about 20 seconds long, that instantly grabs attention for the DualCam PIP iOS app (https://apps.apple.com/app/dualcam-pip/id6761638143). The piece should feel fun and energetic from the first frame: bright motion graphics, snappy cuts, upbeat music, and—most importantly—a realistic AI-generated avatar who speaks with an unmistakably upbeat, enthusiastic tone. The avatar’s script must revolve around one clear selling point: DualCam PIP records with the front and back cameras at the same time, letting users capture both their reactions and the scene in one take. Work that statement into lively, conversational language that fits a TikTok-style pace. Please handle: • AI avatar creation (any reliable platform such as Synthesia, D-ID, HeyGen—your choice as long as it looks natural and lip-syncs accurately). • Scriptwriting and voice selection to match the upbeat, enthusiastic delivery. • Simple on-screen text and animated UI mock-ups that reinforce “Simultaneous Front + Back Recording.” • Royalty-free background track that complements the energy without overpowering the voice. • Final export: 1080 × 1920 MP4, ≤ 20s, ready for social distribution. I’ll sign off once the visuals feel dynamic, the message is crystal clear within the time limit, and audio levels are balanced for mobile viewing. Looking forward to seeing your creative spin on this quick promo. So... download the iphone APP (https://apps.apple.com/app/dualcam-pip/id6761638143) and send your idea to make the video using AI demostrating features of Dualcam PIP ... Having a deal, you win U$ 20.00 for an AI made video. Thks all...
