The NVENC H.264 high profile provides up to 16% bitrate savings (BD-Rate measured with VMAF) compared to the main profile. Since most users do not explicitly set a profile, changing the default benefits the common case. Users requiring the main profile for legacy decoder compatibility can still set it explicitly. The change is gated behind a versioned define so it only takes effect on the next major version bump (libavcodec 63).
