Comment (by spookybathtub):

 I'm not disputing that this file is 422.  I'm just saying it is
 theoretically possible for the 422 codec to contain 12-bit precision.
 From the [https://www.apple.com/final-cut-
 pro/docs/Apple_ProRes_White_Paper.pdf whitepaper]:
 >Like Apple ProRes 4444 XQ and Apple ProRes 4444, all Apple ProRes 422
 codecs can in fact accept image samples even greater than 10 bits,
 although such high bit depths are rarely found among 4:2:2 or 4:2:0 video
 sources.
