  hi
  I compress video a lot using a variaty of different codecs but mainly the Microsoft DV one. I just found out that you can actually uncompress video to its original hi quality, and im wondering how i do this in AE?

  thanks

  I think you may have your mires crossed a little here…

  Uncompressed video is video that has been digitised or created at an uncompressed resolution, not something that has been compressed and subsequently UN-compressed.

  Once you create / digitise / compress a video using a codec which discards a certain amount of data, it is impossible to get that data back unless you have a source of a higher resolution to refer back to.

  DV codecs compress at 5:1, which means you are discarding data which you can’t get back. Create your AE movies as uncompressed AVIs or MOVs to retain maximum quality, whatever your destination.
