I built an n8n workflow that automatically creates hours-long wave / ambient music videos using Suno.
Input a music theme, background video, and number of tracks → the workflow generates songs, merges audio + video with ffmpeg, and auto-uploads to YouTube with AI SEO metadata.
Fully hands-off once set up.
