I am having a problem trying to encode my files from FCP-4 to MPEG-2 to send via ftp to be broadcast from a local cable station's primary insertion server . I am trying to use Apple's Compressor and FFMPEGX or Bitvice Helper to mux the audio and video. These are the specs I need to achieve: "System Streams, CBR, 6Mbit, IBP Closed GOP, Resolution 352 or 720, I frame distance 3, Audio Bit rate 19.2K, Sample rate 48K, standard layer 2, 4:2:0". Any suggestions on how to go about this would greatly be appreciated. If nreed be, I can transfer the edited DV file to my PC. I am only working with 30 second spots. Thanks in advance.
