[FFmpeg-user] recording @ 120fps on mac fails with 'activeVideoMinFrameDuration not supported'

what you are seeing is from the status line during the encode... this shows you the current encoding frame rate. if its below  the specified framerate, the 'speed' value at the end of that line will be less than 1.

basically your current system hardware, and current ffmpeg encoding options can not encode in 'real time'.

if you press q to stop the encode, and then use ffprobe on the file, you will notice that it encoded a 120fps file.
