VOD Encoding
Overview
MK.IO’s Video-on-Demand (VOD) encoding allows users to process video files into various formats and bitrates to ensure optimal playback quality and compatibility across different devices and networks.
Concepts
MK.IO’s video processing consists of Transforms and Jobs.
Transform: A transformation process that will run on the input asset supplied by a job. MK.IO supports single bitrate and multi-bitrate transforms that allow a user to transcode their video into H.264 or H.265 output content. The output content can range from SD to 4K resolutions based on the templated selected.
MK.IO only supports encoding transformations. Other types of transformations will launch soon.
Jobs: A job contains an input asset, output asset location, and reference to a template. The template instructs the job what transform to run to generate the desired output. Many jobs can use the same template.
