TimeUi is a custom timeline node system designed for ComfyUI, aiming to create a timeline similar to those found in video/animation editing tools, but without relying on traditional timecode. Users can easily add, delete, or rearrange rows, providing a smooth user experience. The system supports image upload and management, allowing users to directly upload images to nodes or attach other 'upload image' nodes, streamlining workflows. Additionally, each timeline row contains multiple customizable settings, such as toggling the visibility of image masks, enhancing control over image adjustments. Nodes can work independently or collaborate with other external nodes, allowing for easy toggling of settings like IP adapters, image inversions, attention masks, clip visuals, and masks to fine-tune the output.
