I verified they are supported, but you need to be extremely careful with 
the flags you pass to ffmpeg.  You also need to be careful with the 
resolution of your images as that effects the bitrate ( -b:v ). And as 
Carl pointed out, the frame rate must be a fraction and that fraction 
must be a valid fraction by the AVID specs.

For DNxHR 444, this line should do it:

$ ffmpeg -i test.%04d.tif -r 60000/1001 -codec:v dnxhd -profile:v 
dnxhr_444 -b:v 880M  -pix_fmt yuv444p10 -y test_hr444.mov

For DNxHQX, the following line should do it:

$ ffmpeg -i test.%04d.tif -r 60000/1001 -codec:v dnxhd -profile:v 
dnxhr_hqx -b:v 880M  -pix_fmt yuv420p10 -y test_hqx.mov
