Test card: Difference between revisions

YSTV's '''''ystvtest''''' VT is composed of four different static 1080p test cards followed by 4:3 [[w:SMPTE color bars|SMPTE bars]] on a 50% grey background, with 5s [[w:white noise|white noise]], 5s [[w:pink noise|pink noise]] then a 20 second [[w:hearing range|20Hz - 20kHz]] logarithmic sine sweep at -6 [[w:dBFS|dBFS]], in a 1050x576 progressive-scan [[w:PAL|PAL]] ([[w:pixel aspect ratio|square pixel]]) H.264 MP4-contained video at 10Mbps VBR with 48kHz 320kbps AAC stereo audio. The test card can be played out over the [[Technical:Vision Path|vision path]] to check, at various stages: chroma rendering, luma rendering, cropping, scaling, distortion (whether the image is stretched or squashed along one axis, using the circles), contrast, combing and interference. The audio tones can be used to calibrate volume to known levels, and to compared the frequency response of equipment.
