Correct sizing of images for video presentation?

    Hi,

    I'm trying to make a video that contains some home video (DV), along
    with many still photos. I'm using Premiere Pro 2 on Windows XP, and I
    have Photoshop 6.0 for processing images. I'm a little unclear about
    how to size the still images so that they will be the correct size in
    the final video. (The final video is going to be projected onto a
    screen for a party.)

    I'm using a 4:3 aspect ratio in my video: 720 x 480. So far I've
    scanned in photos at 600 dpi, because I plan on doing pan and scan in
    Premiere (like in a Ken Burns documentary) on a bunch of the photos and
    I wanted to make sure I have high enough resolution. But I don't really
    have any experience doing this, so I really don't know what resolution
    to use for my photos, and whether I need to use a higher resolution for
    pan and scan.

    So my questions are:

    1.) Is 600 dpi a logical resolution to use? Is that overkill, since
    this will never be printed? For some reason, it feels like using an
    actual resolution of 720 x 480 for the images is not enough--that they
    will be blurry or pixelated when the video is projected. But I could be
    totally wrong (and probably am).

    2.) Any special considerations re: doing pan and scan? In other words,
    does that affect the resolution or how I should size the photos?

    I'm doing this video as a surprise gift for my parent's 50th
    anniversary party in early January. So time is running out and any help
    would be GREATLY appreciated.

    Thanks in advance.
    John

    Don't size the images at all (as long as they are under 4,000 x 4,000
    pixels). Just adjust the scaling once the clips are on the timeline.
    Premiere will do the re-sizing for you.

    See above -- it doesn't matter as long as the image is smaller than 4,000 x
    4,000 pixels. The higher the resolution, the more you can do with zooming
    in and out and panning across (the so-called "Ken Burns" effect).
    Yes. If you zoom in on an effective resolution of 720 x 480, you'll get
    fairly pronounced digital artifacts, e.g. blocking.

    One word of advice; save your scans in jpeg format. I did a project
    using tiff files. Some worked, other pixilated wildly, especially
    through the transitions. The jpeg format always worked. I don't know
    why the tiff failed, but jpegs are smaller, and they work.
