> Extract the **first frame** and **last frame** from any video — directly in your ComfyUI workflow.
A lightweight, zero-config utility node for [ComfyUI](https://github.com/comfyanonymous/ComfyUI) that takes any video input and returns the first and last frames as standard `IMAGE` outputs. Works with direct file paths **and** image batches from other nodes like [VideoHelperSuite](https://github.com/Kosinkadink/ComfyUI-VideoHelperSuite).
