2. What is color sub-sampling? What are the drawbacks or benefits of 8-bit color? What are the drawbacks or benefits of 10-bit color?
Color can be used as a tool to contribute more depth to a story. For example, in the movie, "The Matrix", the actual matrix takes on a more green hue to mimic the "green" associated with early computers in the 90s, whereas the real world uses more natural coloring in order to differentiate the two worlds. Color can also be used to emphasize themes, which is shown in American Beauty with their red, white, and blue color scheme. Color sub-sampling is the process of reducing the color resolution while keeping the luminance resolution the same. 8-bit is fine for playback, but some drawbacks of 8-bit color are that it "breaks" when there's not that much color data available. 10-bit is able to hold about 4x as many levels of color compared to 8-bit.
