    Am assembling footage for a corporate video. The client has given me
    several DVDs. Some of these are 16:9 and some are 4:3.

    What is the best way to convert the 16:9 for use in a 4:3 video? The
    par dimension of the the 16:9 is 1.

    I am asking about resizing not DVD to AVI conversion. I have Super
    file converter as well as Premiere CS3.


    Thanks for any insight.

    Letterbox if you need to see everything. Otherwise, you can crop the sides,
    or use pan-and-scan, which will be the most labor intensive.

    Just make sure that the project format is 4x3 in Premiere Pro CS3 and it
    will automatically add the black bars at the top. Same goes for Encore...

    Sorry guys, don't know where that par dimension came from. It's late.

    Here are some descriptors from Super file converter:
    Width : 720 pixels
    Height : 480
    Height : 480 pixels
    Pixel Aspect Ratio : 0.844
    Display Aspect ratio : 1.778
    Display Aspect ratio : 16/9

    Does that make it any clearer? Do I have to do anything with the pixel
    aspect ratio? Also, don't understand why it is 720 x 480 yet is 16/9.

    Thanks guys.

    just set your project in whatever editing program you use to 4:3 that's what
    you want to end up with.
    The reference to 720 x 480 is the resolution not the aspect ratio

    It's "anamorph" 16:9. In other words, you've got a 4:3 aspect ratio image in
    real pixels, with the horizontal dimension squeezed. It's intended to be
    unsqueezed by the display device.

  7. He can unsqueeze it using a DVE horizontal scaling effect in his NLE
    system. Right click on the clip and it will be under "properties" or
    "transform" or something like that. Different depending on specific
    system, but they can all do it.

    I say center-punch the 16x9 shots to get a 4x3 and then it will
    intercut with all the other SD 4x3 just fine, end of story.

    Thanks for your contributions, gentlemen.

    One thing I did not tell you….the footage is usually made up of the
    content of what once was two 16x9 screens. Sometimes these are
    arranged vertically; sometimes they are arranged horizontally
    (stacked). It's the content of multiple screens in an exhibit.

    So, this is what I have done. See if there is a problem….

    I imported the footage (720x480) into Premiere. I interpreted the par
    to 1.2. I then scaled the video so that it all fit in the frame.

    The down side to this, as someone mentioned, is that the video is much
    reduced in size, but all of the original footage is within the frame.
    And thus, the original composition is intact. For my purposes right
    now…I am logging…I think this is best.

    Sound reasonable?

    And have a great 4th weekend
