I handed Claude Design one of my brand's design systems to see how good a video editor, motion designer, and sound mixer it was. Opus 5.5 also wrote the Suno v6 prompts: a 150 bpm song and the 10 sound effects used here. Suno gave me 2 takes of each and I picked my favorites by ear. Claude can't hear, so it measured tempo, loudness, and every drop to cut the sound. Then I passed it to Claude Code to render frame by frame and stitch the mp4, since the render was so big Claude Design kept crashing. Here's the end result. Insane 1st render.
