Summary

Extend an existing video task by providing its Task ID and an optional extension prompt, optionally waiting for the extension task to complete before returning results.

Inputs

  • Task ID (required) — ID of the video task to extend.
  • Extend Prompt — Optional prompt to guide the video extension.
  • Reply URL — Webhook URL to be called upon task completion.
  • Reply Ref — Custom reference passed back in the webhook callback.
  • Wait for Completion — Whether to poll and wait until the extension task completes (default true, polls every 3 seconds up to 5 minutes).

Output shape

a single JSON object with task details and extended video results

If 'Wait for Completion' is true and the extension task ID is returned, the node polls the /api/v1/veo/record-info endpoint every 3 seconds for up to 5 minutes until the task is complete or failed. If waiting is disabled or no task ID is returned, it immediately outputs the initial API response.

Examples

Example 1: Extend a video with a new prompt and wait for completion

Set 'Task ID' to the existing task's ID, enter an 'Extend Prompt' for the extension, optionally provide a 'Reply URL' and 'Reply Ref', and leave 'Wait for Completion' enabled to receive final extended video data.
