What it does

Adds a human-in-the-loop gate to B-roll repurposing. On publish, the workflow generates a clip for each paragraph, drops them into a Slack review thread with approve/reject buttons, then posts only the approved clips to social and quietly archives the rest to Dropbox for later reuse.

When to use it

Use it when brand safety matters and you can't auto-post AI-generated video unreviewed. Best for teams that want speed of generation but a final human sign-off before anything goes public.

How it works

  1. 1A blog publish event triggers the workflow.
  2. 2The post body is split into paragraphs and Replicate generates a B-roll clip for each.
  3. 3The clips are posted to a Slack review channel with approve and reject actions.
  4. 4A branch waits on the reviewer's decision per clip.
  5. 5Approved clips are published to social platforms; rejected clips are archived to a Dropbox 'unused-broll' folder for future use.
