What feature of Zipstream technology primarily aids in saving bandwidth?

Zipstream technology is designed to optimize video streaming by utilizing smart compression techniques that significantly reduce bandwidth usage without compromising video quality. The feature that primarily contributes to bandwidth savings in Zipstream is dynamic bitrate allocation. This method adjusts the video quality in real-time based on the complexity of the scene being captured, ensuring that bandwidth is allocated efficiently.

In scenarios where there is little action or detail, the bitrate can be reduced, minimizing the amount of data transmitted. Conversely, during scenes with more movement or intricate details, the bitrate can be increased to maintain clarity. This adaptive approach ensures that bandwidth is conserved during less demanding visual moments while still delivering high-quality footage during critical events, making it a crucial aspect of Zipstream technology.

Other options such as resolution enhancement, compression of static images, and adaptive frame rates contribute to overall video quality and performance but do not specifically focus on optimizing bandwidth in the same manner as dynamic bitrate allocation does. Each of these features plays a supportive role in enhancing the user experience, but the primary mechanism for saving bandwidth is through the intelligent adjustment of bitrate in response to scene complexity.
