    Hello,

    I have the following MacBook:

    * 2.16GHz Intel Core 2 Duo
    * 1GB 667 DDR2 SDRAM - 2x512
    * 120GB Serial ATA @ 5400 rpm

    I am working on a movie project in Final Cut Express and was given an HD file to incorporate which has the following specifications:

    Format: HDV 1080i50, 1440 x 1080 (1888 x 1062), Millions
    16-bit Integer (Little Endian), Mono, 48.000 kHz
    16-bit Integer (Little Endian), Mono, 48.000 kHz

    FPS: 25

    When I open it in Quick Time, Final Cut Express and iMovie I get audio but no picture. Also, when I launch Quick Time, I get a message that Quick Time is missing some additional elements and directs me to this site:

    http://www.apple.com/quicktime/resources/components.html?os=OSX&ctype=696d6463&csubtype=68647633

    I watched some HD videos off the Apple site and they played just fine, even the 1080p ones.

    Am I then missing a codec? Does anybody have any recommendations on how to get the video to play and show in Final Cut express as well.

    Thank you in advance!

    Only FCP can edit a native HDV file (which is what you have). Final Cut Express and iMovie transcode HDV into AIC (apple intermediate codec) when you capture it from the camera. I'm not sure if there is any other way to get the codec than to purchase Final Cut Studio.

    Thank you for the quick reply! However, according to the Final Cut Express Manual:

    "Final Cut Express HD supports capturing, editing, and output of HDV media using the Apple Intermediate Codec."

    and

    "Final Cut Express HD supports the following HDV formats:
    Format Easy Setup Dimensions Video Data Rate
    1080i60 HDV - 1080i60 1920 x 1080 25 Mbps
    1080i50 HDV - 1080i50 1920 x 1080 25 Mbps
    720p30 HDV - 720p30 1280 x 720 18.3 Mbps"

    Doesn't this mean that the codec is inbuilt into FCE? Yet, the files do not open in FCE.

    FCE (and iMovie) only supports HDV via transcoding the HDV signal into the Apple Intermediate Codec upon capture and working w/it that way. It won't work w/native HDV files and unfortunately that's what you were given. If the person who gave you the file could make an AIC version of it then you would be golden.
