The final step in the TV commercials production process, this is simply getting your TVC on air.
Once your TVC has received its CAD classification and CAD number, it needs to be ‘despatched’ via the likes of Adstream or Dubsat to the TV station.
Generally, only a few stations run TVCs in true High Definition (HD) being 1920x 1080 pixels and these include 7mate, Nine NPC HD, One HD and WIN TV HD. However, the number of stations broadcasting in HD is growing. The vast majority of stations broadcast in Standard Definition (SD) which is 1024 x 576 pixels. It is important to know which stations will be running your ad before you despatch, because if it’s one of the HD stations, then you should supply your ad in HD to those stations so it looks much better. The visual quality will be around 5 times that of Standard Definition, jagged edges will be a thing of the past and the colours will be much closer to how the ad was originally graded. Even if your ad will be on a SD channel, some actually recommend despatching an HD file to Adstream, which after it’s reduced to SD, might actually come out a bit better compared to supplying a SD file in the first place.
There are many technical requirements for a TVC to meet broadcast requirements such as:
There are strict requirements relating to the audio aspect of your TVC, which must be OP48 compliant. This needs to be stated on the clapper board. In addition, it must comply with FreeTV OP59 which is a loudness check.
This is a still image that plays on the video file before the commercial itself and is essentially information to identify and place the ad in the right spot. Clapper Boards typically include the Key Number, the client, production, duration, aspect ratio, date of production and indication of OP48 compliance.
While this might be self explanatory, it’s important to note that the ad must maintain the same aspect ratio throughout its duration, that means it must be either 16:9 or 4:3 aspect ratio.
The TV spectrum has a certain range of ‘legal’ colours and luminance. For example, if the whites in your TVC looks too ‘hot’, it’ll most likely exceed the legal spectrum and the ad will need to have this adjusted so it meets the requirements, before it can be aired.
After meeting the various technical and other requirements, your TVC has to be delivered as a video file. Acceptable video formats are:
All the above need to supplied at 25 frames per second.
In terms of audio requirements, except for the Mpeg 2, the codec must be PCM (uncompressed), channels must be stereo, the bitrate must be 16 bit, little endian and the sample rate must be 48kHz.
After producing your TVC, it’s important that you’ve got the right professionals guiding you through the rigorous despatch process as briefly outlined above. Rocket Productions handles all despatch services for our TVC clients, so you rest assured that the ad will play as planned.
