We built our own video editor and text overlay generator as Video-to-film pulldown patterns we wanted to generate.

Spears and Munsil are best known for their analysis and testing ofĭeinterlacing chipsets, so it’s no surprise that the disc includes a full suite This ensures that there is no bleed or artifacting caused by compression.” “We shifted the borders betweenīars slightly so every one of them is on an AVC or VC-1 macroblock boundary. “We noticed that lots of color bar patterns have small artifactsĪt the borders between the bars,” said Spears. It’s a convergence problem or a decoding problem.”Įven a classic pattern like the ubiquitous Color Bars gets the Spears and Our pattern can show you that kind of alignment issue, and show you whether We’ve seen modern players that misalign the chroma channels up or down. 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. Proud of our Chroma Alignment pattern,” he added. That most image-processing software uses.” “Chroma patterns are especially tricky, because youĬan’t create them properly with full dynamic range in the RGB space Minimize artifacts and preserve all of the detail and bandwidth,” saidĬo-creator Don Munsil. 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.
