    iTunes Video and Audio Asset Guide

    Posted by Reda Alouache on December 20, 2016 at 12:10 pm

    Hello everyone,

    I’m desperately looking for info on how to be able to make the right video/audio format and not get refused by iTunes Store.

    According to their iTunes Video and Audio Asset Guide 5.2.6 Specs, and to my understanding, the HD Video format must be in the format below:

    Video Spec:

  • Apple ProRes 422 (HQ) or 4444 or 4444 (XQ)
  • VBR expected at ~220 Mbps

    • Audio Spec:

  • MPEG-1 layer II stereo
  • 384 kpbs
  • 48Khz
  • Included in the same file as the delivered video

    • Container Spec:

  • Deliver all content in an MPEG-2 Program Stream file container
  • The .mpg file extension is expected for all MPEG-2 content
  • Audio must be delivered muxed with the video stream

    • After 2 overnights of work and research, It seemed to me impossible to get all specs together in 1 File!

    Is there a way to make a Prores 422 HQ codec and “Mpeg-1 Layer 2” audio wrapped into an Mpeg-2 PS container?
    Or i misunderstood their spec document?

    and one more question, any resources could teach/help making all the necessary to meet the ITunes Store high standards?

    Thank you very much for the help.

    Regards,
    Reda Alouache.

      Telestream Switch Pro
      Will QC and deliver iTunes packages

      Streamlined creation of iTunes store packages Pro
      Choose the iTunes export preset to create packages ready for distribution to the iTunes store. This creates an asset-only iTunes package file (a .itmsp file) which includes the media content, secondary subtitle or audio files, chapte      r information, and an XML file.

      Thank you for the reply.

      I’ve downloaded the demo version of switch 3.

      I tried it with a music video delivered as a Mov-Prores4444-PCM Linear to convert it into Itunes Music Video HD, i got this message “Switch does not currently support ProRes in an Mpeg-2 Program Stream, which is required for this profile”. Any idea how to solve that!

      Please take a look at the steps taken.

      Thank you.

      Sorry but that’s not enough information to troubleshoot. If Switch fails it gives you messages explaining the failure.
