Encoded Media Files

These are the start of sample media formats that may be useful in software testing and Video CD production.
 
Note: Color bar test patterns were accurately generated by software that was provided by SyntheticAperture. The lower left section of the SMPTE pattern will only be accurate when the IQ (deep blue and purple) color encoding is generated by a test card or similar equipment as they can't be accurately reproduced using RGB values since the I represents the chromatic blue and the Q represents the chromatic red of the Y'CbCr sampling that analogue video uses. However these days IQ calibration is no longer used due to the modern design of today's video displays.
 
There is also an ASCII-styled version of this chart.
