Help Needed for N8N Workflow: Content Creation Automation

I'm looking for assistance setting up an N8N workflow for content creation involving various AI applications. The workflow should process video/audio files on local SSDs, including categorization, sync and clip talking head interviews, and generate copyright-free music.

Additionally, it should scrape the internet for competitive insights and social media metrics, while all outputs should integrate into a locally saved XML file for Premiere Pro. I have a basic N8N setup with Docker and Digital Ocean, but need guidance on tying everything together.
