ADDITIONALLY:

  • Check tape specifications provided by the airing station/network.
  • Understand that Aberdeen clones/dubs your master straight across (Analog stays in component video and Digital stays in SDI) and is not responsible for off-spec masters.
  • Aberdeen does not provide technical evaluations. We will gladly pass on any information you include to the airing station.
  • Do not send us the only copy of your original master; send us a clone or dub. We are not responsible for damage or loss during shipping.
