Reel-Studio

A creator hears a Reel and wants to make something with its sound, but only needs the drums, one passage of the song, or a voice without background noise. Getting there can involve a stem separator, an audio editor, and a video editor, followed by another import into Instagram. The creative idea is simple; the workflow is fragmented. Meta identified this broader problem when launching Edits: video creation can require multiple apps and complicated workarounds. Adobe and Harris Poll's September 2025 survey of over 16,000 creators across eight countries found that 60% had used multiple creative generative AI tools in the previous three months. This is broader workflow context, not a measurement of Instagram audio-editing demand. Reel Studio brings audio adaptation into one conversational workflow. Upload a clip and ask: "Keep only the drums," "Slow seconds four through eight without changing pitch," or "Make this music beat land at this point in my video." The app renders the edit, lets you compare it with the original, and supports another instruction to refine it. The working build includes music stem isolation and mixing, text-guided sound selection, speech denoising, trimming and looping, speed and pitch changes, uploaded-music alignment and ducking, and audio, video, and stem exports. Timing edits transform the video with the audio. Saved revisions, undo, and A/B preview keep creative control with the user. An ad studio also creates 15- or 30-second promotional cuts from the edited footage and soundtrack. Muse Code turns creator intent into validated edit plans; Meta's HT Demucs makes musical components independently editable. Specialized workers render the media. Edits already supports audio reuse; our proposed extension adds conversational source editing and refinement. The current app is standalone and exports files for manual import into Instagram. Built during the hackathon: the interface, backend, planner, model-worker integrations, synchronized timeline, revision history, exports, and ad compositor integration. Upstream models and renderers are credited in the repo. Rights-aware direction: Instagram's Original Audio label is not blanket copyright clearance. This prototype is for media users own or have permission to edit. A native version would preserve source attribution and reuse settings, and allow catalog transformations only where Meta's licenses permit. Separation grants no new rights; ads and exports need clearance for their use. Platform rights checks are proposed, not implemented.
