wanted to make my own take on anthropic’s “there’s more to discover” ad without opening a video editor. made it with swift-render, an open-source engine i’m building: you write the video as swiftui + metal shaders and it renders on your mac (this one takes about 5 seconds). the fun part was how. swift-render has an editor called studio where you can leave a note right on a frame. i’d pause on whatever bugged me (“beats are messed up”, “make the blob real glass”) and claude code would find the code, fix it, render that frame, look at it, and reply with the new frame. 38 notes, a commit per round. what i learned: * make it look at its own frames. that caught most of the bugs before i ever saw them. * keep every cut on the beat. when it merged cuts to hold my favourite shots longer, the whole film fell off the music. * notes as files + a commit per round means you can change your mind as much as you want. free and MIT:…
