I need full uncut console output.

But lets play little guessing game:

colorbalance works in rgb colorspace only and whatever you used to view video
does not support such h264 profile, use something like this:

 ffmpeg -y -i input.mp4 -vf "colorbalance=rs=-0.5:bs=0.5:bh=-0.5:rh=0.5"
 -vcodec libx264 -r 29.97 -bt 3000k -pix_fmt yuv420p outputvid.mp4
