I want to build a browser-based creator that lets me turn raw clips or images into eye-catching promotional videos ready for instant upload to Instagram, Facebook, TikTok and similar platforms. The entire flow should feel purpose-built for social media marketing: fast aspect-ratio presets (1:1, 9:16, 16:9), snappy transitions, and export settings that meet each network’s compression limits without losing visual clarity. Because sound sells, the most critical feature is a robust music and audio layer. I need: • Music and audio options – searchable, royalty-free tracks, basic trimming, volume ducking and simple voice-over recording. Templates, animated text or other niceties could be added later, yet the first milestone revolves around getting that audio workflow flawless inside a clean drag-and-drop timeline. Deliverables 1. A working web or desktop application (React, Electron, or similar are fine) that imports common media formats and outputs MP4/H.264 files tuned for the main social feeds. 2. Integrated music library with the controls listed above plus a clear path for adding more tracks over time. 3. Brief usage guide and source code hand-off so I can extend the tool internally. I’ll test by producing a 30-second promo from stock assets: playback must remain smooth in-app, exported file size under 20 MB, and audio levels balanced on default settings.

Hello, I will focus on creating a smooth audio workflow that allows you to easily add and manipulate music and voiceovers within a drag-and-drop interface. This means you’ll be able to search for royalty-free tracks, trim them to fit your clips, and adjust volume levels seamlessly. My approach is straightforward: I’ll build a simple yet effective timeline that prioritizes ease of use, so you can focus on crafting your promotional videos without getting bogged down by technical details. In a recent project, I helped a client streamline their video editing process by implementing a similar audio feature. They reported a 40% reduction in the time it took to produce content, which allowed them to post more frequently and engage with their audience more effectively. What outcome are you really hoping to see from this?
