The "format" of the output of the overlay filter
is yuva420p. This is not supported by x264, so
the output "format" file-wise is yuv420p.
The output is visually gray because you
overlayed a gray frame (x1) over another
frame (of the same size).
Sorry if I misunderstand your issue, please
remember that not everybody is a native
speaker (actually most are not).
