Video Levels
Levels must be in accordance with ITU BT.601 for SD content, ITU BT.709 for HD content, and in accordance with EBUR103 recommendations.
Audio
The program loudness level must be normalized to -23 LUFS (+/- 0.5 LU) and -1 dBTP max.
- UK Specifications require the first 6 frames and the last 6 frames of the spot to be mute. Please be advised content will need an audio mix that meets this specification.
