    Rendering Red

      Whenever I render out in after effects using the render queue or export (usually render queue) anything the colour of red is pixelated, not by a huge amount,but you can definitely notice it compared to the other colors. ive tried using lots of different formats to save out as, but it always does it, even when i rendered out a jpeg sequence.
      does anyone know why this is? ive tried it on a few computers and get the same results, its not just one project, ive encountered this problem alot.

          Huh? Sorry, you have to be more specific. Source formats? Effects? Color profiles? Bit depth? CoDecs? Things getting pixelated would only happen if somehow you screw your ranges, but otherwise I never have heard of that. All channel operations are weighted equally and thus what you describe is impossible other than by user error. The only thing that would explain it to me would be the use of OpenGL, but you're not doing that, are you?

            Chroma sub-sampling:

            If you render to a lossless format such as QuickTime Animation @ 100% you will not get the same "pixelation." One way of making it less visible is the lower the saturation of the red color and lower the contrast to the adjacent colors.
