Encode DTT captured video to Apple iPod Touch format MPEG4

This command:
  • tries to use ffmpeg codecs for decoding
  • nicely deinterlaces the video
  • crops the edges off the video
  • scales the video to a 16:9 representation that will fit onto the iPod Touch with no further scaling
  • encodes the video using libx264 to the best quality MPEG4 AVC (h.264) it can
  • encodes the audio using libfaac to MPEG 4 AAC at 128Kbps
  • multiplexes the audio and video using ffmpeg's MPEG4 file container file format

This file WILL NOT play on the iPod Touch. It needs extra headers inserted which can be done with NicMP4Box.exe

NicMP4Box.exe -add output.mp4 ipodTouch.mp4
