H264 Single Bitrate 4K
Media Encoder Standard
defines a set of encoding presets you can use when creating encoding jobs. You can either use a preset name
to specify into which format you would like to encode your media file. Or, you can create your own JSON or XML-based presets (using UTF-8 or UTF-16 encoding. You would then pass the custom preset to the encoder. For the list of all the preset names supported by this Media Encoder Standard
encoder, see Task Presets for Media Encoder Standard.
This topic shows the H264 Single Bitrate 4K
preset in XML and JSON format.
This preset produces a single MP4 file with a bitrate of 18000 kbps, and stereo AAC audio. For detailed information about profile, bitrate, sampling rate, etc. of this preset, examine the XML or JSON defined below. For explanations of what each element in these presets means, and the valid values for each element, see the Media Encoder Standard schema topic.
Note
You should get the Premium reserved unit type with 4K encodes. For more information, see How to Scale Encoding.
