Automatic Duck had two plug-ins for Premiere Pro: Pro Import PPro for importing from Final Cut Pro and Avid and Pro Export PPro for exporting a sequence's audio tracks to OMF for sending to Pro Tools or Nuendo. Both of these products were discontinued in the summer of 2006 and these plug-ins are not available. Users interested in interchanging with Premiere Pro can consider AAF as an interchange format. Premiere Pro reads and writes AAF files natively, as does Avid editing systems. Final Cut Pro can read and write AAF files with Automatic Duck's Pro Import FCP and Pro Export FCP plug-ins.
