The patterns we put up first on every show: bars to prove the colour path, a crosshatch to prove geometry and cropping, greyscale and near-black steps to set screens, and pixel checkers to prove a route is pixel for pixel. Each one comes at 1280x720, 1920x1080, 1920x1200, 2560x1440, 3840x2160 and 4096x2160.
What's in the pack
- EBU 100/0/75/0 colour bars.
- Crosshatch with circles, a one-pixel border and EBU R 95 safe areas.
- 11-step greyscale, a smooth ramp, near-black steps (0 to 10%) and near-white steps.
- One- and two-pixel checkerboards and line pairs: the quickest way to catch scaling.
- Black, white, 50% grey, red, green and blue fields for dead pixels and seams.
- Aspect ratio guides (4:3, 1:1, 9:16, 2.39:1) and a raster ident with pixel counts along each edge.

Using them on a show
Play them from the source the show will use, at the show raster and frame rate: the media server, the playback machine or the presenter laptop. A pattern that looks right from a different source proves nothing about the route the show takes.
The PNGs are 8-bit, full-range RGB. Players and encoders map them to video range on output. If the near-black or near-white steps look wrong, check that mapping before you touch the screen settings.
