​
What this node does

Video Picker is a Compose stage (ComfyTV/Compose). Upstream stages that produce video—Video Stage and any node whose runs accumulate multiple clips—feed into this node. The node body shows the accumulated clips; whichever one you click becomes the sole COMFYTV_VIDEO on the video output. There is no ▶ Run. Clicking a clip updates the hidden selected_index and re-emits the output snapshot instantly, so downstream stages immediately see your pick. Media flows as ComfyTV project snapshots, not native ComfyUI tensors. To hand a picked clip to native ComfyUI nodes, insert a Bridge — see bridges.md.

​
When to use it

  • A Video Stage returns several clips across multiple Runs and you want to review and keep one.
  • You generated variant clips (different seeds/prompts) and need to choose the best motion.
  • You want to accumulate clips across Runs into one pool and pick without losing earlier ones.

​
Parameters

​
batch (upstream)

The wired input, of type COMFYTV_VIDEO and optional. Each generated clip that arrives here is appended to the pool. Wire it from a Video Stage video output.

​
selected_index (hidden)

1-based index of the clip to extract (default 1, range 1–999). You never type this—it is set by clicking a clip in the node body.

​
pool (hidden)

Accumulated video pool, stored as JSON on the node. The UI appends new upstream clips (deduped by URL) so they survive regeneration and disconnect, and empties it via the Clear button. When the pool is non-empty it is the source; otherwise the live batch input is used.

​
project_id / parent_output_id (internal)

Hidden; maintained by the Project node and graph wiring. You rarely touch these.

Outputs

Tips

  • Nothing appears until you actually click a clip—selection, not hover, sets the output.
  • Pool cluttered with old clips? Use Clear in the node body, or drop in a fresh Video Picker.
  • The pool persists selections and clips with the project, which native in-memory tensors cannot—use a Bridge only when crossing to native nodes.
  • Video Stage — common upstream; generates clips from text/image.
  • Image Picker / Audio Picker — same pick-one-from-a-pool pattern for other media.
  • Load Video from Asset — pull an existing clip from the project asset library instead of picking from a pool.
