    v2 v3  
    22First, I'm running MacOS and I've been unable to run the script as it is. Not sure why. You should consider adding information in your book on the differences in script development (and execution) between window and other OSs, such as linux and MacOS.
    33In the meantime, I've been removing the variables from the script and creating single command lines like so:
    4 - - - - - - -
     4
    55ffmpeg -f lavfi -i nullsrc=size=640x640 -vf "format=gray8,geq='clip(128-128/11.5*(180-191.5/(640/2)*hypot(X-640/2,Y-640/2)),0,255)',v360=input=fisheye:output=e:ih_fov=191.5:iv_fov=191.5,format=rgb24" -frames 1 -y mergemap.png
    66
    77ffmpeg -i in.mp4 -i mergemap.png -lavfi "[0]format=rgb24,split[a][b];[a]crop=ih:iw/2:0:0,v360=input=fisheye:output=e:ih_fov=191.5:iv_fov=191.5[c];[b]crop=ih:iw/2:iw/2:0,v360=input=fisheye:output=e:yaw=180:ih_fov=191.5:iv_fov=191.5[d];[c][d][1]maskedmerge,format=rgb24" -t 10 -y out.mp4
    88
    9 - - - - - - -
    109
    1110However, running the first command above gives me this error:
    12 - - - - - - -
