Step-by-step workflow

  1. 1. Deploy Self-Hosted n8n & FFmpeg Worker on Hostinger Cloud VPS

    Provision a Hostinger KVM Cloud VPS running Docker Compose with n8n, PostgreSQL, and an FFmpeg container. Self-hosting eliminates per-operation workflow taxes when handling large audio buffers and multi-minute video webhooks.

  2. 2. Structure Phonetic Pacing Tags in Your Script Database

    Connect a Google Sheet or Airtable base to n8n to manage your content calendar. Format scripts with explicit SSML-style breath pauses and phonetic spellings so the narration timing is locked before any video credits are consumed.

  3. 3. Generate Master Audio Track via ElevenLabs Turbo v2.5 API

    Trigger an HTTP Request in n8n or Make.com to the ElevenLabs Text-to-Speech endpoint with stability set to 0.45 and clarity at 0.80. Pass the output through your local FFmpeg container to normalize loudness to -14 LUFS and trim dead air.

  4. 4. Execute Audio-Locked HeyGen Avatar v2 API Render

    Upload the normalized MP3 URL directly to the HeyGen V2 Video Generate API as the master audio source rather than using HeyGen's internal text input. This guarantees 100% lip-sync precision and prevents expensive avatar credit re-renders.

  5. 5. Automate Webhook Ingestion & Multi-Platform Syndication

    Configure an n8n Webhook node to listen for the `avatar_video.success` event from HeyGen. Automatically archive the final MP4 to cloud storage, update your Google Sheet cost ledger, and schedule uploads to YouTube, TikTok, and Instagram Reels.

Ready-to-use AI prompts

Prompt

You are an elite retention scriptwriter for automated faceless YouTube and TikTok channels. Convert the user's raw topic into a high-retention script optimized specifically for ElevenLabs AI voice synthesis. Rules: 1) Write in short, punchy clauses of 8-14 words. 2) Insert explicit pacing markers like `<break time="0.4s" />` between key transitions. 3) Spell out complex acronyms phonetically so the TTS engine never stumbles. 4) Output a JSON array containing `scene_number`, `spoken_text`, `estimated_seconds`, and `b_roll_visual_prompt`.

Prompt

Act as an AI Audio Engineer specializing in ElevenLabs API orchestration. Analyze the provided script segment and return the optimal JSON payload parameters (`stability`, `similarity_boost`, `style`, `use_speaker_boost`) along with rewritten punctuation (using em-dashes and ellipses) to maximize vocal emotion, natural cadence, and zero robotic drift before passing the audio to a lip-sync video avatar.

Prompt

You are a Principal Media Automation Engineer. Given an array of pre-rendered ElevenLabs audio URLs and scene descriptions, generate a valid HeyGen V2 `/v2/video/generate` JSON request body. Map each audio URL to an `audio_url` voice object, assign the specified `avatar_id` with `avatar_style: normal`, configure 1080p dimensions, and inject dynamic background URLs for each scene transition.
