All TV destinations in the UK require 6 frames of mute at the start and end of the commercial.
Please refer to the UK & ROI Technical Specifications for full details.
This does not apply to Sponsorship destinations, although there are some exceptions.
When selecting Sponsorship in the UK please choose from either of the following Ad types
16:9 TV Sponsorship with slate
16:9 TV Sponsorship with slate (0 frames mute)
Sponsorship destinations that do require 6 frames of mute are:
Channel 4 Sponsorship
Channel 5 Sponsorship
HGTV | Really Sponsorship
All other UK sponsorship destinations do not require 6 frames of mute
Please note that although it is possible to send Sponsorship files with 6 frames of mute to destination that accept 0 frames mute, the reverse is not true. You cannot send files with 0 frames mute to destinations that require 6 frames mute. In this instance the files would be rejected by the broadcaster.
