 > **The shipped example needs the [VideoHelperSuite](https://github.com/Kosinkadink/ComfyUI-VideoHelperSuite) pack.** It uses the node types `VHS_LoadVideo` (reads the video) and `VHS_VideoCombine` (writes the restored video). VideoHelperSuite is an **optional dependency of the example only** — the pack itself does not import it, and the two other example nodes (and every node of this pack) work without it.
