Comment (by cehoyos):

 Iiuc, the issue is that the noise filter does claim to support yuv422p16
 but the output is not what you expect.
 Could you test the following command line?
 $ ffmpeg -f lavfi -i testsrc -vf format=yuv422p16le,noise=c0s=10:allf=t
 -vcodec mpeg4 -qscale 2 -t 1 out.mov
 I believe I see the issue now myself.
