    For the Internet I am creating a 20min Video based on a simple Powerpoint
    Slideshow with spoken Text.

    How did I do it? Simple:
    I saved the Slids as small .jpg's (with 400x300 px (as this should play in a
    window with about 350x255 px) build my movie in Premier Pro1.5 importing the
    ..jpg's into Premier and saved this as .wmv!
    The result is unsharpness in the slides specially visible where text is
    WHY? Certainly there is a very well explainable reason for this

    As I export the video via Adobe Media Encoder as .wmv
    (Windows Media Video 8 for local Area Network (256 Kbps) with a frame
    Width/Height of 320/240 pixels) that I should export the .jps as exectly
    this size 320/240 ?

    Its called saving in losey jpeg format. the compresion causes artifacts and
    it playes havoc with text add to that you compressed again to WMV try
    exporting as tif to premier

  3. .... Although I can't think of one right now, when PhotoStory can do
    all this for you, if you needed WMV output in the first place,
    together with optional transitions, voice overlay etc etc ;-))

    Since PS3 uses an optimised image codec, you won't get that
    "unsharpness" unless you use non-recommended settings.

    A very strange figure to suggest. Any particular reasons?

    that's the standard format size for broadcast level DV. Although 720x576px I think is more correct (oops).

    I think is more correct (oops).

    True - but it's not relevant in this situation (or at least, it shouldn't

    The OP is editing for web delivery at 320x240 or similar. He's saving the
    JPEGs at a slightly higher resolution than this and then applying titles.
    The result is too blurry.

    Even if the working format when in Premiere is DV, the scaled up images will
    appear blurry when working on them, but should lose that blurriness when
    saved as a video with a lower resolution.

    It's possible that the OP is saving the file as DV AVI (or similar) and then
    transcoding that to WMV using an external program such as Windows Media
    Encoder, but I don't think from reading it that that is what he is doing. I
    get the impression that it is being encoded to WMV from within premiere.

    @ the OP - save it as a 320x240 uncompressed AVI. If this file is blurry
    then your problem is with your workflow within Premiere, or with Premiere
    itself. Download Windows Media Encoder and transcode the uncompressed AVI.
    If the result is blurry, then the problem is with your choice of transport
    (WMV) or the parameters being used. If the result is not blurry, then the
    problem is with the way Premiere is serving the images to WME.

    Let us know how you get on...
