    I really need help here, for several month I have been doing animations in After Effects and every time I output them in DV or DV-Pro the movie looks very blured.

    Then I use Jpeg B compression and it lokks perfect, then I take that movie in Quicktime and export it in DV and the same thing... blured a lot.

    Then I was trying a soft called Artmatic Pro (I recommend it) that si a software to create animated fractals. I took a clip captured from a DV camera with iMovie, I aplied some effects and export it in the same format and boom! the same result.

    Why is that?

    It happend to me with QT 6 in 9.2.2 and OSX as well. When I capture with iMovie everything looks fine but once I export something it looks terrible. I know it could be the fields but I do not mess with that.

    I've been told that this is normal and that when you burn it to a DVD it looks fine. Have you tried making a DVD and how does it look?

    DV is a compressed format (5:1 compression w/4:1:1: color sampling) so what it sounds like you are seeing is the difference between an uncompressed animation being compressed into DV.

    Not really because when I create something in After Effects it looks blury but when I play a clipin QT captured with iMovie it looks perfect. I have been dealing with thsi problem for a long time and I do not have any body that can explain that to me.

    Do you have that problem? try taking any movie and export it to DV. I can go from Cinepack to Sorenson with the expected results but no reason that something that is not compresed looks blured in DV.

    Maybe you have a settings issue? I've been using AE w/FCP for a year now and I've never had any issues like you are describing.

    Make sure you have Quicktime Pro and turn on High Quality in the video properties (command-j). This makes DV material look good (high quality interlaced->progressive) when played in the Quicktime Player.

    That is generally the case... DV is a format made with the finished project in mind: a television set

    DV is great for a lot of things, animation and motion graphics aren't two of them. It's a codec that comes with some compromises. If your final out put is TV or DVD you'll probably be ok. If your final out put is playback on a computer via quicktime, embedded media in powerpoint, etc. you'll be much better off using a different codec. MPEG-4 has worked great for me.
