What is dithering in video?

Dithering is a technique you can use to make a lower bit-depth blend colors by introducing random noise to the image in strategic locations. When is dithering useful? - When you need to represent an image with lower bit depth than you captured it at, or when you need to use a low bit depth in general.

Does dithering reduce quality?

In such a requirement, dithering is a process that can help in the reduction of the size without losing the quality and much information of the data and helps in minimizing the quantization error.

What is the purpose of dither?

Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images. Dither is routinely used in processing of both digital audio and video data, and is often one of the last stages of mastering audio to a CD.

Should I enable dither?

In general, you should apply dithering any time you're rendering audio to a lower bit depth (like converting from 32-bit to 24-bit, or 24-bit to 16-bit). On the other hand, if you're exporting something like a 32-bit file, you usually don't need to worry about dither.
