Show HN: SynthCut – An open-source, local-first AI video editor (github.com)

SynthCut has emerged as an innovative open-source, AI-driven video editor, empowering users to perform multi-track, frame-based edits entirely offline. Unlike traditional video editing software that relies on manual operations, SynthCut allows users to articulate their editing requests in plain language, with an AI processing those commands via the Model Context Protocol (MCP). This design significantly enhances user experience, making video editing accessible and effective for creators who may not be proficient with traditional editing tools. The editor's use of FFmpeg ensures that all video processing remains local, safeguarding user privacy while enabling sophisticated functions such as per-clip transformations, color grading, and automatic captioning through the Whisper speech-to-text model. With 85 MCP tools at its disposal, users can enjoy a non-destructive editing timeline that syncs AI and human inputs in real time. SynthCut positions itself as a versatile tool for both professional video creators and casual users, facilitating seamless project management and editing. Additionally, an alternative hosted solution, relo.video, is available for those seeking a straightforward, automated video generation experience, showcasing the growing trend of integration between AI technologies and creative workflows in the multimedia landscape.
