Comment (by rivierakid):

 Thanks, I made several attemps:
 AV_PIX_FMT_YUV422P - no artifacts
 AV_PIX_FMT_YUV444P - no artifacts
 AV_PIX_FMT_RGB24 - artifacts
 AV_PIX_FMT_YUV422P10LE - artifacts, IMHO this format would be ProRes
 native, I was playing only with luma component.

 So I've changed my opinion, the problem could be in built-in color space
 conversion :o)

 BTW ProResLT has lower quality then the original Apple ProResLT, is it
 possible to set bitrate? It seems that it completely ignores -b
 parameter...
