Anthropic has no video model. so how did Claude just animate a beating heart? six still images from ChatGPT went in. Claude Opus 5.5 wrote every frame of motion in code, locked the heartbeat to the kick drum and composed the phonk and violin track itself the whole thing runs on free tools: 1. Python + NumPy every squeeze, warp and glow is math on pixels. the heart beats 60 times a minute because one line of code says so 2. OpenCV moves the camera, blurs the edges like a macro lens and blends each shot into the next 3. Pillow draws the HUD, the live ECG line and the blood counter on every single frame 4. SciPy the music. violin, 808, electric piano and the heartbeat kick are all synthesized from scratch, zero samples 5. FFmpeg stitches 708 frames and the audio into one mp4 want to go further? GSAP and Motion Canvas handle UI style motion, Three.js gives you real 3D no video model needed. save this for the next time someone says AI video means paying for credits
