The old days of analog, vertical chroma alignment was never a problem. And it allows you to check both vertical and horizontal alignment.

It’s easy to see an offset of as little as a quarter-pixel, which we think is aįirst. Tell if the chroma channel is aligned properly with the luma channel.

Software generates the patterns in the native color space of Blu-ray, withoutĪny unnecessary color space conversions or rounding. A whole suite of chroma-channel evaluation patterns make it easy toĮvaluate chroma reproduction separately from luma. Shows how much of the 1080p image is being cropped by the player and/orĭisplay.
