Desktop video editor 2

Open-source After Effects alternative for GPU-powered motion graphics Premation is a free, open-source desktop motion-graphics editor designed as an alternative to Adobe After Effects. It combines timeline-based compositing, keyframe animation, graph editing, 2.5D cameras and lighting, text animators, rigging, vector tools, particles, effects, and deterministic GPU rendering in one application. Premation uses WebGPU when available and WebGL2 as a fallback, while its viewport and export pipeline share the same rendering engine so approved previews match final exports. Projects are saved locally as .motion files, and the editor supports formats including SVG, Lottie, MP4, WebM, ProRes, PNG sequences, GIF, image sequences, and WAV audio.

Desktop video editor for collaborating with AI coding agents HyperFrames Studio is a desktop video editor built for AI coding agents by the team behind the open-source HyperFrames framework at HeyGen. Users describe a video and an AI agent creates it with HTML, CSS, and JavaScript. The user and agent can work together on a shared timeline, while the app provides a live preview, hot reload, property panel, source editor, and file browser. Changes remain in editable project files rather than being flattened into exports. The app is available for macOS and Linux, with Windows support coming soon.
