Aphelion Editor is a node-based video compositing application for real-time editing, visual effects, and motion graphics. It provides a graph system where video pipelines are built by connecting 77 built-in nodes, with instant preview and export from any viewer. The workspace includes a node graph, timeline, media pool, property inspector, and a float32 RGB viewport for accurate color work. Real-time playback is achieved through proxy decoding, frame caching, and prefetching, enabling smooth interaction with complex graphs. Projects are stored as JSON files with autosave, and export options include MP4 and PNG sequences.
