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...
