When delivering files to platforms for online broadcast, there are normally requirements around channel layout and positioning, stream types, and channel metadata labelling. This page shows how Engine has solutions for all of these. Remember that every module can be incorporated in to a workflow, so whilst doing any of the functions shown here, you could also for example, be processing for Loudness Compliance, and so on.
Engine’s Channel Mapping module can be used to flexibly reorder channels so that the right tracks are in the right places. In the example below, we are starting with an eight channel file, and the layout is stereo followed by 5.1. If our delivery specification needed 5.1 followed by stereo, then we could use the workflow below to reposition the two tracks.
Engine can convert any input stream format to any output stream format. This function has the following common uses.
When Engine is processing a file, you can configure Engine to maintain the original stream structure in to the new file, rather than specifically choosing a new format. However if you do select an output stream structure, then you can also add metadata to describe the audio.
Engine has the ability to insert various types of metadata, although the choices supported are determined by filetype. With OP1A MXF files, Engine can insert Language tags to the DMS-1 specification, or Language and Channel Position tags to the AS11 specification. The example shows a workflow where the first two channels are a stereo pair, in English, and the next two channels are a stereo pair in German.
