What is colour depth and palettes and how does it all affect my Director movie?
The term colour depth refers to the amount of graphics memory (measured in bits) allocated to each pixel (or dot) in an image, and determines the number of colours that can be used to display that graphic. For example, an image set to 1-bit colour depth means that any pixel in the image can only be one of two (2 to the power of 1) colours (black or white in this case). An 8-bit image allows each pixel to be set to any one of 256 (2 to the power of 8) colours, and is generally preferred because it represents a good compromise between colour quality and speed of handling. It is important to understand that the colour depth of the whole movie can be different to (and always at least equal to) the colour depth of any individual image. Your computer may be set to High Colour (16-bit colour depth), meaning that the movie you produce will inherit that colour depth when you save it. If you run a movie on a computer set to a lower colour depth than the movie’s colour depth, then there will be s
