Comment (by rivierakid):

 Testing with test.tif http://www.datafilehost.com/download-5f72f895.html
 -vcodec 210 no artifacts
 -vcodec prores artifacts in gray square

 I wonder about bitrate settings, for prores_kostya there is a
 global_quality parameter (prores_kostya.c), which controls the bitrate
 (there is a four items-bitrates tab for every profile). But I don't know
 how to control quality in "prores"? Is it equal to "prores_anatolyi"?
 Because I can't find a source code for it and seems that "prores_anatolyi"
 auto-selects the quality...
