What Is Wrong With This CCTV Footage?

This footage found on the Courier Mail site shows a typical camera setup that should give good ID images given the tight scene.

While the results are reasonable, there are two key areas that should be addressed to improve the over all results.

The amount of roof at the top of the scene is excessive.

• 25% of the image is wasted on a concrete slab that no one is ever going to come through.
• The fluorescent light and exit sign are potentially causing the contrast to be worse than it could be if the camera was not looking at them.

The other improvement is on the compression.

• There is a significant amount of macro blocking (square pixalated areas) as the people move through. This is often a sign of poor video compression technique or too much compression to try to improve storage times.
• Without seeing the original video this cannot be confirmed as a DVR issue or the recompressing done by the web site
