You should be able to replace ls with find
find . -iname "*.mp4" | parallel ffmpeg -i {} -c:v dnxhd -profile:v dnxhr_hq -pix_fmt yuv422p -c:a alac {.}.mov
This one does work, but it instantly consumes my entire system RAM (32GB) and the whole pagefile. It proceeds to kill a lot of background processes complaining about “device memory full” and once it completes it generates a lot of 0 byte .mov files (more than half of all).
That is probably the impact of parallel. Try limiting the degree of parallelization with this:
find . -iname "*.mp4" | parallel ffmpeg -j 2 -i {} -c:v dnxhd -profile:v dnxhr_hq -pix_fmt yuv422p -c:a alac {.}.mov
That will only let 2 jobs run at the same time. You can change the number after -j if you want to run more than 2 at once.

Unrecognized option 'j'.
Error splitting the argument list: Option not found
Oops, I put it in the wrong spot. Try this:
find . -iname "*.mp4" | parallel -j 2 ffmpeg -i {} -c:v dnxhd -profile:v dnxhr_hq -pix_fmt yuv422p -c:a alac {.}.mov
