File Submissions

  • Please note that VPAID tags are not currently accepted
  • ABC Digital Media Mezzanine File Format requirements
  • It is our intent to provide the highest possible experience to the consumer for both content and advertisements. As such, we ask that all file based deliveries follow the following guidelines:
    1. HD is preferred over SD. If an HD asset is available please provide this format.
    2. SD advertisements should not be letterboxed. Because the players are all 16×9 ratio, providing a letterboxed 4×3 video will significantly reduce the size of your advertisement as it will be both letterboxed and pillarboxed in the player and/or device.
    3. Please provide the highest quality digital master QuickTime file available within the technical specifications below. If your asset does not meet the technical requirements, do not convert your file to fit the specifications. Instead return to your digital master or tape and recreate the QuickTime mezzanine file.
    4. Video must be broadcast quality and void of any visible compression artifacts.
    5. Audio must be stereo, in sync with video and void of any distortion.
    6. Files must be in QuickTime format (specs below) with all file names ending in .mov.
