iTunes Delivery Requirements

Technical guidelines for delivery to iTunes.

The VoD platform iTunes has strict delivery requirements and processes for delivering assets. In addition to the technical guidelines for the actual AV Container, iTunes requires a comprehensive package of metadata for the programme or film. Due to the complex overall delivery, producers often use firms who specialise in delivery to iTunes.

The Executive Summary presented here, for delivery to iTunes is not legally binding. Please refer to the Handbook for iTunes video 5.2.

iTunes HDTV profile for TV programs:

  • Apple ProRes 422 (HQ) or 4444 or 4444 (XQ)
  • ITU-R BT.709 colour space, labeled correctly with 709
  • Expected variable bit rate is 88-220 Mbit/s
  • HD encoded dimensions accepted to support square pixel aspect ratios 1920x1080 or 1280 x 720
  • HD encoded dimensions accepted to support non-square pixel aspect ratios (this allows delivery of HD video in the native dimensions of the best original source, although must be discussed with an iTunes representative prior to delivery) : 1440x1080, 1280X1080 or 960x720.
  • MPEG-2 container or .mov container with integrated audio (stereo or 5.1 with min. 48kHz)
  • frame rates 23.976, 24, 25 and 29,97 are supported
  • interlaced content must properly be labeled as "interlaced" and the field assignment must be defined in Quicktime container.
  • Crop dimensions must be provided in the metadata for content with inactive pixels through letterbox, pillarbox or windowbox.

Content upscaled from SD will be rejected

Native frame rate of original source:

  • 29.97 interlaced frames per second video source can be delivered either interlaced or de-interlaced properly tagged as progressive
  • 24 and 25 frames per second must be delivered progressive
  • 23.976 frames per second for inverse telecine must be delivered progressive; must not be delivered interlaced or delivery will fail
  • Field dominance must be properly tagged (top field first, bottom field first, or progressive)
  • Fields and frames may not be duplicated or eliminated to create a broadcast frame rate (for example, telecine, NTSC to PAL conversion)
  • For mixed frame rate material please contact your iTunes Technical Representative

All video must begin and end with at least one black frame. In addition, videos can only have empty edits in the last edit of the edit list; videos with empty edits other than the last edit will be blocked.
