The “Smart Cut” node is a multi-track timeline container. It opens a full-screen editor where you join, layer and export several clips into one finished video.

## Open the timeline editor

Add a “Smart Cut” node from the “Add node” menu (marked Beta), or select a video node and click “Smart Cut (multi-track)” on its toolbar. Connect the clips you want to use to this node, then open it to enter the full-screen timeline editor.

## Multi-track editing

The editor is a multi-track timeline. Common actions (the shortcuts work inside the editor):

- Play or pause the preview: Space;
- Split a clip at the playhead: ⌘/Ctrl + B (B alone switches to the blade tool; S toggles snapping);
- Delete the selected clip: Delete or Backspace;
- Undo / redo: ⌘/Ctrl + Z and ⌘/Ctrl + Shift + Z; ⌘/Ctrl + S saves a version;
- Drag a clip to move it, snap it, or reorder it on the same track; drag a clip's edge to trim its length;
- Esc closes the open menu or clears the selection; press ? to open the shortcut list.

## Export

In the “Export film” menu at the top right of the editor, first adjust the output settings (format MP4 / WebM / GIF, quality, bitrate, cover, range, audio), then choose where to export:

- Export to device: downloads to your computer automatically when rendering finishes;
- Export to canvas: appears on the canvas as a new node when rendering finishes;
- Export audio only: exports just the timeline's sound.

“Export project (XML)” in the same menu hands the timeline to other editing software so you can keep cutting there. If the timeline has a gap with no clip covering it, you only get a notice; it doesn't stop the export. There's also a one-click “Close gaps” at the top.
