Asset conversion transform

An Asset Conversion transform allows conversion from a variety of input formats to an MP4 asset. Such transform will ingest a live event recording or a VOD asset and generate a set of MP4 files depending on the selected preset.

Such transform can also be used to convert legacy AMS events or older MP4 files to the latest format. Once in the latest format, you can benefit from the latest features such as thumbnails, side loading of subtitles or even AI based transcription and translation.

MK.IO provides two built-in presets that enable conversion from an input asset to an MP4 asset:

• CopyTopBitrateInterleaved: Generate a single MP4 file using the top bitrate video along with all audio interleaved. Using this preset, a single MP4 file will be created. This file requires a Predefined_DownloadOnly or a Predefined_DownloadAndClearStreaming to be delivered.
• CopyAllBitratesNonInterleaved: Copy all video and audio streams from the input asset as separate video and audio output files. Using this preset will generate an asset with the following files:
  • MP4 files (.mp4), one per video or audio rendition.
  • Server manifest (.ism) used as the access point for streaming endpoints.
  • Client manifest (.mpd).
  • Index files (.mpi), one per rendition (used to enhance performance of the streaming delivery)
• CopyAllBitratesInterleaved: Copy all video streams from the input asset as separate video files with all audio interleaved. Using this preset will generate an asset with the following files:
  • MP4 files (.mp4), one per video rendition with all audio interleaved.
  • Server manifest (.ism) used as the access point for streaming endpoints.
  • Client manifest (.mpd).
  • Index files (.mpi), one per rendition (used to enhance performance of the streaming delivery).

When selecting an asset conversion transform, you will only need to select the source asset, no need to select a source filename, MK.IO will figure it out for you.
