ffmpeg -i INPUTFILE -map 0:v -an -c:v dnxhd -pix_fmt yuv422p -trellis 0 -profile:v dnxhr_lb -y OUTPUTFILE.mov
crf: The range of the quantizer scale is 0-51: where 0 is lossless, 23 is default, and 51 is worst possible. A lower value is a higher quality and a subjectively sane range is 18-28. Consider 18 to be visually lossless or nearly so: it should look the same or nearly the same as the input but it isn't technically lossless.
