Auto Motion Studio: Local-first AI video editing for Windows

Hi Product Hunt — I’m the maker of Auto Motion Studio. I built Auto Motion Studio because video creators are often forced to choose between two extremes: fast automatic editors with very little control, or professional editors that require many repetitive manual steps. This application is designed to bring both approaches into one local-first Windows workspace. The workflow starts with guided automation. Auto Motion Studio can analyze imported footage, detect and remove silent sections, generate captions, balance and enhance audio, correct color, add impact effects, suggest an editing plan, and prepare the project for review. The result remains editable instead of becoming a locked one-click export. For precise work, the editor includes a multi-track timeline and four purpose-built workspaces: - Standard keeps media, preview, inspector controls, narration, and the timeline visible together. - Dual Monitor places the source and program views side by side for detailed comparison. - Timeline Focus gives more space to the preview and tracks for timing-intensive edits. - Thumbnail Design provides templates, text, shapes, layers, crop controls, and recommended frames in a dedicated canvas. Audio and narration are part of the same workflow. You can record narration inside the editor, use voice-synthesis tools, adjust audio, and choose from 100 built-in CC0 BGM tracks without searching for separate music files. Auto Motion Studio is local-first: media and core editing can remain on the PC. It supports built-in and connected local AI options, remembers editing preferences with user control, and provides both English and Japanese interfaces. It is intended for creators, small teams, educators, product demonstrators, and anyone who wants automation without giving up manual control. What it includes: - Automatic silence removal and caption generation - Audio balancing, color correction, and impact effects - A multi-track timeline with Standard, Dual Monitor, and Timeline Focus workspaces - Narration recording and voice-synthesis support - 100 built-in CC0 BGM tracks - A dedicated thumbnail design workspace - Built-in and connected local AI options - Non-destructive review and adjustment before export - Editor preference memory with user controls - English and Japanese UI The official Windows release is available for $129 / ¥19,800. I’d especially value feedback on the editing workflow, performance, accessibility for first-time editors, and the creator workflows you would like us to improve next.
