Much of Tooscut's heavy data lives outside the V8 heap. We use WASM linear memory which is not counted against V8 heap. GPU buffers is in VRAM. Bitmaps are also native allocations.
Also, video files are never fully decoded. We use the browser's native WebCodecs on demand. Only a small buffered window gets decoded and sent to the compositor. So it can even handle long 4K videos.
