Title Safety
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.
Video Levels
All video signals should comply with ITU-R BT.709-5 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. Following EBU recommendation Rec.103-2000 they will therefore allow a small tolerance, assuming that no more than 1% of the active picture is in error.
Audio Levels
The loudness level of the programme material must be in agreement with the EBU R128-2014 directive, including the following delivery specifications:
EBU R.128-2014
• Integrated Loudness** Program : -23 LUFS
• Target Level Tolerance : +/- 0.5 LU
• Maximum True Peak : -1dBTP
• Maximum Momentary : No Limitations
• Maximum Short Term Momentary (3 Sec) : -18 LUFS
• Loudness Range : No Limitations
**'Integrated Loudness' is the definition for the target of the 'Programme Loudness' stated in metres in conformity with EBU Tech 3341.
Although the maximum true peak is -1dBTP, it is recommended by the broadcasters that the true peak should not exceed -3dBTP.
IMPORTANT Notes Regarding Audio Silence
• For the UK there must be a MINIMUM of 6 frames of audio silence at the start and end of the commercial
• Digital silence should achieve a recommended level not exceeding -70dBFS.
• Trace audio within the first or last 6 frames is a QC fail.
