Any chance those AVX-512 optimizations they released a while ago work within this? [1]

I think WASM SIMD is only 128-bit wide.

WASM SIMD is 128-bit wide as dtf noted, so AVX-512 won't apply here. Longer term, WebGPU could be a more interesting path for compute acceleration in the browser than SIMD widening.

Note those only apply to scene_sad which is used for scene change detection and freeze detection and a few other things like mpdecimate -- it's a very specific use case

thanks didn't note that until now lol
