Why I ditched cloud transcoding and set up a mac mini render farm
summary
Claims a browser-driven pipeline using WebGPU, WebCodecs and WebRTC on Apple M4 hardware eliminates CPU↔GPU shuffling via unified memory and therefore beats typical cloud GPU setups for many AI video tasks. Tests show M4 runs AI video 4–5x faster than an equivalent cloud GPU pipeline, rental costs ~5x cheaper than entry-level GPUs, and an end-to-end pipeline that is ~25x cheaper than an Nvidia data-center GPU; demoed a hot-dog detector at ~4 ms/frame with ~1 s glass-to-glass latency on a Mac mini render farm.
