Stop Grinding, Start Automating Video Repurposing
You have a long-form video, webinar, podcast, demo, or event. Instead of endlessly clipping, resizing, and rewriting for TikTok, Instagram, LinkedIn, YouTube, or email, use automation to spin out channel-ready shorts, audiograms, GIFs, and quote cards in minutes. No editing suite, no extra hires.
What You Need
n8n (preferred), Make , Zapier , or Gumloop
An AI video tool (e.g. Lately.ai , Runway , Kapwing , Descript with API)
AI copy (OpenAI GPT-4o, Claude, or Gemini for hooks and captions)
Cloud storage (Google Drive, Dropbox, or direct upload to YouTube, TikTok, Instagram)
Optional: AI transcription (Whisper, Gemini, or built-in tools)
Step 1: Detect & Ingest New Videos
Monitor uploads: Set up a Google Drive Trigger or Dropbox Trigger node in n8n (or use Make/Zapier) to watch your video uploads folder.
Auto-transcribe and segment: Send the video file to an AI platform (Descript, Runway, Lately.ai) via HTTP node. Let it detect chapters, “wow” moments, and segment boundaries.
Alternatively, run audio through Whisper or Gemini for transcript and timestamps.
Gotcha: For large files, chunk into
Step 2: Find and Extract the Best Clips
Auto-highlight top moments: Ask your AI tool or OpenAI: Extract 3-5 most engaging moments from this transcript. For each, give start/end timestamps, a short summary, and suggest a platform-specific hook.
Optionally, use sentiment/emotion analysis to flag the most dynamic segments.
Tip: Edit your prompt to include audience themes or your brand voice for better hook alignment.
Step 3: Auto-Create Assets for Every Channel
Generate formats and captions: For each chosen clip, create: Square (1:1) for Instagram
Vertical (9:16) for TikTok, Reels, Shorts
Horizontal (16:9) for YouTube or LinkedIn
Use Kapwing, Runway, or Descript via API to resize and export. - Send the clip’s text to GPT-4o (or similar) for a viral caption and hashtags: Write a punchy hook for [platform] using this clip. Suggest 3-5 trending hashtags. - Burn in subtitles using Whisper, Gemini, or the video editor’s built-in features. > Gotcha: Each platform has strict length limits. Trim clips for TikTok (max 3 min), Instagram Reels (max 90 sec), YouTube Shorts (max 60 sec). ## Step 4: Store, Distribute, and Schedule - Auto-upload and share: Save finished assets to Google Drive or Dropbox. - Use n8n or Make to directly upload to YouTube Shorts, Instagram Reels, or TikTok via APIs. - Send previews or links to Slack/Teams for instant feedback or review. - Schedule with Buffer, Hootsuite, or Later for timed, multi-channel posting. > Tip: Integrate a scheduler to automate posting at the best times for each platform. ## Which Automation Tool is Right? | Feature | n8n | Make | Zapier | Gumloop | | --- | --- | --- | --- | --- | | Video/Audio API | Custom HTTP, max control | Visual modules, easy setup | Great for basics, limits with video | Drag-n-drop, prebuilt AI nodes | | AI Prompts | Any model, fully customizable | Built-in, many models | Good for simple use cases | No API setup, fastest start | | Cloud Storage | Any provider | One-click all majors | Simple flows | Easy output links | | Cost | Free/open | Usage pricing | Pay-per-zap | Startup plans | ## n8n Quick Node: AI Clip Finder { "nodes": [ { "parameters": { "url": "https://api.openai.com/v1/chat/completions", "method": "POST", "bodyParametersUi": { "parameter": [ {"name": "model", "value": "gpt-4o"}, {"name": "messages", "value": [ {"role": "system", "content": "You are a video strategist."}, {"role": "user", "content": "Analyze this transcript.

Convert files to MP4 or MOV for max compatibility. - Unengaging clips? Add real audience reactions or top comments to your AI prompts for more relevance. - Subtitle sync issues? Use AI tools with auto-alignment for more accurate captions. - Level up: Add a sentiment node to prioritize high-energy moments. - Route drafts to your team via Slack for instant yes/no feedback. - Push analytics data (from YouTube, TikTok) back into the workflow to refine future clip selection. ## Let Your Video Content Work Everywhere With just a handful of automation steps, your videos become a factory of channel-optimized content, with minimal manual work. Set up your pipeline once and let your video library drive results everywhere your audience hangs out.
