Video Levels

All video signals should comply with ITU-R BT.709-5 (HD) and video signals should not exceed the specified limits.

Video levels should not exceed 700mV, or fall below 0mv

Luminance (Y) -1% and 103%
(between -7mV and 721mV)
RGB video levels -5% and 105%
(between -35mV and 735mV)

Out of gamut tolerance

Whilst XR and the Broadcasters will reject illegal video levels they understand there may be instances where it is difficult to completely avoid, and following EBU recommendation Rec.103-2000 will allow a small tolerance, assuming that no more than 1% of the active picture is in error.

Title Safety

16:9 as per EBU R.95-1

All graphics, text, and frame composition elements should be placed within the safe title area to prevent key content from being cut off.
