so I had this idea for a while. instead of using a video model, what if claude just writes the whole video as code? html, gsap, three.js, some shaders, and then a headless browser renders it frame by frame. took 2 days and and a multitude of revisions (the first one was bad, threw it away). I did the direction and the feedback, claude wrote all the code, around 5700 lines. the trailer you're watching was made the same way. I just asked for a trailer and it went through the video, picked the shots, cut them on the beat and even made the music, all synthesized in code. the part I didn't expect, at some point it takes screenshots of its own render, looks at them and finds bugs by itself. two titles overlapping, the mascot standing on top of a chart. nobody told it, it fixed them and rendered again. and the part I love the most: I don't need my NAS with terabytes of footage anymore. the sources stay on git and if I need the video I just render it again.…
