There is a picker per medium: * **Image Picker** — from an Image Stage, Grid Split, Image Variations, Panorama Multi-View, … * **Video Picker** — from a Video Stage batch. * **Audio Picker** — from a Music Stage batch. Common behavior: * Click a thumbnail; the selection is the picker's single-item output. * The Image Picker carries the full **action toolbar** (`✏️ Edit`, `🌐 Panorama`, `📐 Multiangle`, `💡 Relight`, presets). * Generator stages **auto-create** their picker on first Run. *** ## Compare (A/B) A/B compare A before/after **slider** inspector comparing **image\_a** (original) and **image\_b** (edited). *** ## Bigger arranging tools When one picker isn't enough, ComfyTV has larger arranging surfaces: * **Storyboard Editor** — a multi-board drawing workbench (the full layer-editor engine per board) with onion skin, timeline playback, and animatic / GIF / PDF / ZIP export. Fountain scripts import as boards. Storyboard Editor * **Sequence** (Video) — a lightweight track-style clip assembler; see [video-and-audio.md](/guides/video-and-audio). * **Director Timeline + Timeline Render** — a full clip timeline with a one-click render is on the [roadmap](/guides/roadmap).
