Comment (by rivierakid):

 That was not for 444 format, but I've made many test and you're right that
 it's little bit unclear :)

 Reproducing problem:
 test.tif http://www.datafilehost.com/download-5f72f895.html

 ffmpeg -i test.tif -vcodec prores_kostya -profile 1 out.mov
 - result is bad (artifacts)

 ffmpeg -i test.tif -vcodec v308 -pix_fmt yuv444p test.mov
 ffmpeg -i test.mov -vcodec prores_kostya -profile 1 out1.mov
 - result is OK

 Instead of x264 I'm using v308 = uncompressed 4:4:4
