Please    name    the    file    being    uploaded    in    the    form    of    the    flighting    code    of    the    commercial   being sent:    for   example  

Please note that no visual slate or any freeze frames are allowed on the front or back of the file – commercial only.


File Duration


The file duration must be the same duration as the flighting code.  The file must not have a visual slate, colour bars, freeze frames or black frames at the start or the beginning.




Squeezebacks must have a 2 second freeze frame at the end of the commercial.  This is to allow for the DVE so there is not black on air.

Thus a 10 second squeezeback must have a duration of 12 seconds, but the code would still be 10, i.e. ABCD_10_001_E_H




The audio must be R128 (ITU 1770.3) compliant to enable successful file based delivery. The uploaded file must pass our QC process before delivery can be made.

To view R128 guidelines please visit 


The R128 specifications are:

EBU R128 Integrated loudness –23LUFS ±1LUFS

EBU R128 true peak at –3dBTP


This is compulsory for all broadcasters.
