Build a Preview-First Video Caption Removal Workflow in n8n

Description and use

The workflow successfully removes burned-in captions from a sample 12‑second video, returning a temporary URL to the processed video while allowing a preview mode that makes no API calls.

Problem

Burned-in captions in video footage require a processing step before adding new text, and existing subtitle tracks must be removed or disabled.

Outcome

The workflow successfully removes burned-in captions from a sample 12‑second video, returning a temporary URL to the processed video while allowing a preview mode that makes no API calls.

Workflow

• Validate configuration
• If paid execution disabled, return preview and stop
• Import video URL and poll upload status
• Create remove-text job after upload ready
• Poll job status and return result URL
