AE Scripts has a new script by Christian Lett, qp_Bars, which generates SMPTE color bars for video. There are four bar options:

* SMPTE color bars with PLUGE
* PAL colour bars (the color bars run the full height of the image)
* SMPTE HDTV color bars
* 16:9 color bars (as HDTV bars but the colour bars run the full height of the image)

The Colour Bar Intensity slider changes the intensity of the seven color bars only (default 75% for SMPTE defined bar values). All other bars are constant.
