Both cameras offer in-camera electronic stabilization, but this is an area where there’s a significant difference. GoPro is leaning on the new generation of in-camera electronic stabilization that’s used in the Black. They’re calling it HyperSmooth. I’ve done some side-by-side testing of HyperSmooth compared with the standard stabilization used in the Silver, and I’ve found that HyperSmooth is indeed much better.
