File Layouts (NLE Sequences)
Most broadcasters have moved to complete file-based workflows, avoiding the use of tape and manual processes. This level of automation requires not only media files, but trusted associated metadata (unique identifiers, titles, content lengths, etc.).
At the non-linear editing stage, certain guidelines can help us ensure the validity of the metadata provided along with your media files. This in turn can add smoothness and accuracy to the entire workflow as your original files are cataloged and prepared for air. Below, are diagrams that represent proper layouts within non-linear editing software, depending on whether you are producing spots with slates or without them.
The single most important element to notice in these diagrams is that commercials should end with a single frame of black. Knowing this information allows our system to determine the duration of your commercial and to protect it from being clipped at the wrong position during ingest.
We strongly recommend not including any slate, black, bars, or tone before or after the actual content. Depending on how broadcasters analyze audio levels, tone can negatively impact automated audio normalization.
Option 1. Commercial without slate or black (STRONGLY PREFERRED)
When you add new files to our system we collect all important metadata about these files—this information is forever linked to associated files. Therefore, slates are not really necessary and are deemed optional.
Option 2. Commercial with leading slate and black
If you are producing spots preceded by slate and black, it is important note the position in the layout where the actual commercial starts (relative to the beginning of the slate). This position is commonly known as start point, start of message, or simply SOM.
HD and Center-Cut Safety
Some stations only accept 16×9 HD material with a 4×3 safe title area.
Some viewers still watch our stations and your advertisements on Standard Definition 4×3 aspect ratio television sets. Our cable and satellite distribution partners as well as all “Set Top Boxes”, by default, center cut 16×9 HD material during the down conversion process. Therefore, any important information outside this area will not be seen on 4×3 televisions.
Audio Layouts
When uploading files into Fig, you are required to specify an “Audio Layout” option. An audio layout refers to the arrangement of audio channels in the file and the type of audio (stereo, surround sound, etc).
All channels must be contained in one single multi-channel track.
Multiple mono tracks are also accepted.
Multiple tracks containing more than one channel per track are not accepted.
Audio Layout Options:
Channel 1 – Stereo left (or mono)
Channel 2 – Stereo right (or mono)
Channels 3 and up (if any) – silence
Channel 2 – 5.1 Right front (RF)
Channel 3 – 5.1 Center (C)
Channel 4 – 5.1 Low-frequency Effects (LFE)
Channel 5 – 5.1 Left rear (Ls)
Channel 6 – 5.1 Right rear (Rs)
Channels 7 and up (if any) – silence
Channel 1 – Stereo left (or mono)
Channel 2 – Stereo right (or mono)
Channels 3 through 6 – silence
Channel 7 – Stereo left or mono
Channel 8 – Stereo right or mono
Channels 9 and up (if any) – silence
Channel 2 – Stereo right (or mono)
Channel 3 – SAP left (or SAP mono)
Channel 4 – SAP right (or SAP mono)
Channels 4 and up (if any) – silence
Channel 2 – 5.1 Right front (RF)
Channel 3 – 5.1 Center (C)
Channel 4 – 5.1 Low-frequency Effects (LFE)
Channel 5 – 5.1 Left rear (Ls)
Channel 6 – 5.1 Right rear (Rs)
Channel 7 – Stereo left or mono
Channel 8 – Stereo right or mono
Channels 9 and up (if any) – silence
SAP means Second Audio Programming.
DVS means Descriptive Video Service and is also called Audio Description.
Not all stations accept files containing surround sound, SAP, and/or DVS.
** You much check with each station before submitting your file. **
