i finally cracked long-form AI ads with GPT-6 Astra...

my setup now produces 5min+ videos on autopilot in 4k 60fps, here's how it works (running inside Codex):

- it starts in the meta ads library, pulling the winning ads in the niche before writing a single line
- from that research it writes the full script, every scene mapped before anything generates
- image models handle the character and environment sheets
- video models handle the actual sequences
- Suno generates the soundtrack to sit under the whole thing
- one CLI controls what generates, in what order, and with which model
- delivery comes out with cinematic motion, fluid camera work, any ratio from vertical 9:16 to widescreen 21:9

i explain how to build this in the article below:
