Yes, -vf format=gray is working!
Thanks to all, especially to Roger Pack.
Carl Eugen, yes, gray alone is sufficient. Moreover, format=yuv422p is
incompatible with the high profile.
Is it sufficient to code grayscale video with 50% of bitrate comparing
to color coding? I dont know about yuv420p (have no idea about planar
formats), but in yuv422 50% of bits belong to luminance channel.
