  <p>Did anyone encounter such a thing? 
  Do you know of a way to solve this? </p>

Comments.Text: This is most likely a resampling problem like @nchpmn suggests. It could also have to do with the codec you're using for your output. If you're using a 4:2:2 or other chroma-subsampling codec, you can also see degradation in the resolution of the outputs. It can be particularly noticeable in the saturated reds and blues.
