I honestly didn’t expect this to work. I gave Opus 5.5 our website and asked for a premium launch video. It researched the product, wrote the creative direction, coded every animation, composed an original score, mixed in my voice-over and a live demo call, and rendered it in 1080p. What blew my mind most was the feedback loop. I’d say things like “the logo isn’t aligned” or “lower the music 10% under the voice,” and it just did it, precisely. Happy to answer questions about the process.
