In video streaming, what happens to the bitrate with increased scene complexity?

In video streaming, an increase in scene complexity often results in a higher bitrate. This is because more complex scenes typically contain more details, motion, and a wider range of colors, which require additional data to accurately represent them. Bitrate refers to the amount of data processed in a given amount of time, and when the visual information in the scene is more intricate, the encoding algorithms need to allocate more bits to maintain video quality.

For example, a simple scene with little motion and minimal detail can be encoded using fewer bits, whereas a complex scene, like a busy street or an action sequence with fast movement and numerous elements, needs a greater bitrate to avoid pixelation and maintain clarity. Consequently, as the complexity of the scene increases, the necessity for a higher bitrate becomes essential to preserve video quality. This leads to the conclusion that with increased scene complexity, the bitrate typically increases.
