Turn videos into Twitter threads, LinkedIn posts, and blogs with WayinVideo and GPT-4o-mini

Description Submit any video URL — podcast, webinar, interview, or YouTube video — along with the title, creator name, niche, target audience, and tone and the workflow transcribes the full recording automatically. WayinVideo's Transcription API returns a speaker-labeled, timestamped transcript which is sent to GPT-4o-mini in one call to produce all three content pieces simultaneously: a 10-tweet Twitter thread, a 200–300 word LinkedIn post, and a 600–800 word SEO blog post with HTML structure, meta description, and focus keyword. Word counts are tracked for all three pieces and everything is saved as one row in Google Sheets with Status set to Draft. Built for content marketers, solo creators, agencies, and social media managers who want to repurpose every video into three platform-specific pieces without writing anything manually. --- What This Workflow Does - Transcribes the full video with speaker labels and timestamps — WayinVideo's Transcription API returns every word spoken in the video with the speaker name and timestamp so GPT has full context to work from - Generates all three content pieces in one GPT call — The Twitter thread, LinkedIn post, and blog post are all produced together — saving API cost and keeping the voice consistent across platforms - Produces a 10-tweet Twitter thread with a hook and CTA — Tweet 1 is a scroll-stopping hook, tweets 2–9 cover one insight each from the transcript, and tweet 10 is a CTA with the video reference and hashtags - Writes a platform-appropriate LinkedIn post — A 200–300 word thought leadership post with a strong first line, numbered insights, a closing question, and professional hashtags - Creates a full SEO blog post with HTML structure — A 600–800 word post with an SEO title, meta description, focus keyword, and HTML H2 headings ready to paste into any CMS - Tracks word counts for all three pieces — The Twitter thread, LinkedIn post, and blog content each have their own word count column in the sheet so you can verify length at a glance - Saves 18 fields to Google Sheets in one row — All three pieces, their word counts, the focus keyword, meta description, hashtags, video metadata, and generation timestamp are all in one Draft row --- Setup Requirements Tools Needed - n8n instance (self-hosted or cloud) - WayinVideo account with API access - OpenAI account with GPT-4o-mini API access - Google Sheets (one sheet with a tab named Content Engine) Credentials Required - WayinVideo API key (pasted into 2.
