$ ffmpeg -i input.mp4 -c:v dnxhd -profile:v dnxhr_hq -pix_fmt yuv422p -c:a pcm_s16le -f mov output.mov

This causes a/v desync for me (15 min video). In case if anybody runs into the same, here's the solution:

ffmpeg -threads 16 -fflags '+genpts+igndts' -i input.mp4 -c:v dnxhd -profile:v dnxhr_hq -pix_fmt yuv422p -af 'aresample=async=1,asetpts=PTS-STARTPTS' -c:a pcm_s16le -f mov output.mov

The downside is that it makes sound in DaVinci Resolve preview choppy, but it's fine after final rendering.
