Bandwidth vs. Image Quality Shootoutby Antony Look, posted on
Jul 24, 2011 When thinking about maximizing image quality,
resolution is usually the first thing that comes to mind.
However, resolution is not the only factor that impacts quality.
The amount of bandwidth available and used can have a dramatic
impact on image quality. In this report, we examine bandwidth
and the effect that it has on quality across numerous cameras.
Which Image Quality is Better? To better understand image
quality, let's start by examining two samples of the same scene
side by side: Consider two questions: - Which camera has higher
resolution? A or B? - Which camera is better? A or B? It is
pretty obvious that the image from Camera B is better so this
should be a simple case. The reality is that those images are
from the same camera at the same resolution and frame rate
(720p/30). All that was done to the camera was changing the
Constant Bit Rate target from 512 Kb/s to 8 Mb/s. Factors
Impacting Quality Even with the same resoluti
