Transcode

Transcoding is the process of conversion of digital media from one format to another. Media companies, big and small, use transcoders to convert files for broadcasting, editing, web, mobile, archive etc., to get deliverable formats, as well as to get mezzanine formats like ProRes etc.  and navigate through the confusion of incompatible formats.

During the transcoding process, transcoders may be performing one or all of the following:

  • Conversion from one audio/video format to another,- such as XDCAM to ProRes or Quicktime to VOD
  • Upconverting video from SD to 1080i or 720p or downconverting from HD to SD for playing on smaller screens
  • Lowering bit-rate
  • Simply re-wrapping the file from MXF to quicktime
  • Frame rate conversion,- such as 24 fps to 30 fps
  • And many more

Transcoding is critical to monetize content as content gets delivered to different platforms. However, many issues such as audio/video corruption, blockiness, pixelation, audio/video dropouts, audio clipping, pops & clicks, motion jerks etc. have been found to occur during the conversion process, not to forget non-compliance with audio/video formats or delivery specifications. Failing to meet the delivery spec could cause rejection of content, failure to meet audio/video standards could be even more catastrophic.

Automated QC using Baton

Performing automated QC on the content offers peace of mind and ensures that content meets high quality standards. Baton can ensure compliance to audio/video formats and that none of the above mentioned artefacts affect the quality of content. Users can also QC incoming content to filter out non-standard or incompatible video content, to save on transcoding time and storage needs. The system comes packaged with pre-defined test plans for most popular used formats/specs such as VOD, XDCAM, Netflix etc. Users can use pre-defined or create new test plans as per the unique needs of the workflow, based on file-type or delivery requirements.
