Exploring Video Editing in the Browser
summary
Claims that WebCodecs gives frame‑accurate seeking and hardware acceleration while the plain video element cannot reliably hit frame accuracy; shipping a decoder in WASM works but burns CPU. Using WebGPU and keeping textures on the GPU cuts copy overhead for fast effects. Practical builds push heavy work to server-side rendering with native codecs and stream back via HLS/DASH/WebRTC — it reduces client complexity and enables pro codecs but raises cost and state‑sync complexity.
