The idea of the following testchart is to follow artefacts through HD post-production. The artefacts include color transcoding errors, framing errors, subsampling and compression artefacts.
The computergenerated file is encoded in 8bit RGB space and available as a TIFF file. The file can be imported to a HD-NLE system and inserted into HDCAM tape before processing (these encoding processes will already alter the content).
The chart can then be examined by eye, on the waveform monitor and be exported back to an RGB file to be compared in an image processing program.

The primary purpose of the testchart is to measure its values digitally, with an eydroper tool. Some intelligence was used to layout the color patches in a way that the do not disturb each other too much on a waveform monitor, but the task was rather diff
The testchart is available in multiple resolutions:

What's New:
new layout optimized for waveform, gray scale, charts for 720, PAL, NTSC and NTSC DV.
