Converting .mov for Davinci Resolve

Based off this video on youtube, the recommendations are the following:

Navigate to the folder with your file, and covert with a command like so:

$ cd /path/to/video/folder
$ ffmpeg -i "my-video.mov" -c:v prores_ks -profile:v 3 -qscale:v 9 -vendor ap10 -pix_fmt yuv422p10le -acodec pcm_s16le "my-video 2.mov"

I don't have details one what it's doing, but it changes the codec somehow.
