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 Multiple Bitrate 4K preset in XML and JSON format.
This preset produces a set of 12 GOP-aligned MP4 files, ranging from 20000 kbps to 1000 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.
Note
When modifying the Width and Height values across layers, make sure that the aspect ratio remains consistent. For example: 1920x1080, 1280x720, 1080x576, 640x360. You should not use a mixture of aspect ratios, such as: 1280x720, 720x480, 640x360.
