Adobe Premier Q: How to make a dotted line appear on a map, like used in Indiana Jones?

Discussion in 'Professional Video Production' started by William Gates, Nov 18, 2003.

  1. Hi all,
    I have a video of a map and I'd like to add dotted lines on it so that
    the impression of travelling over the map is given. I'm using premier
    for editing (V 6.5). Anyone have any ideas how I would go about doing

    Two layers, the map below, the same map with the line pre-drawn above. A wipe
    pattern can reveal the lines as if they are being drawn in real time. There are
    many alternate ways to do this effect as well, using the keyer and making the
    line a gradient, etc. etc.

    Splice in those 'dots being drawn on a map' scenes from Indiana Jones,
    Temple of Doom. :)

  4. Make a copy of your map. On that copy you place all your dots where they
    should be when the travelling is finished.

    In Premiere version 6.5 and earlier you then place the two map versions on
    the Va and Vb tracks. Use a wipe transition between the tracks to gradually
    reveal the underlaying final map. Note that you may have to split the files
    and use several sections depending on the direction of the line of dots. The
    angel of the wipe transition is settable.

    You can load your map into a graphics program, and add the dots to it,
    then save it under a new name. In your NLE, you can just do a wipe
    between the picture with no dots and the new picture with dots. This
    works ~OK if the line of dots is fairly straight. You might want to soften
    the edge of the wipe a little to mask the edge going by, but I'm not sure
    premiere has much control over edge softness. It may be a choice
    between hard, and not as hard :-(

    A better way (especially if your map winds through the mountains or a city)
    is to create the line of dots on a separate layer in your graphics program
    (Photoshop?). Then remove the background image (MAP) save the image
    with either a transparent background, or a color you can key. You will be
    creating a numbered sequence, so the file name should reflect the number
    of dots to be placed. Remove the last dot and save again but decrement
    the number. Remove the next to last dot and save again with an appropriate
    number. Keep doing this until all of the dots are gone. All of the file names
    must be the same except for the number, and the numbers must have the
    same number of digits (dots275.psd, dots274.psd . . . . . dots010.psd,
    dots009.psd, dots008.psd . . . etc.) In Premiere, you can load the "image
    sequence" on a layer above your map and the dots will animate on. This
    is a lot of work.

    Yet another way would be to use an animated mask in Aftereffects.
    For this you would create a custom mask and alter it over time to reveal
    the string of dots. This is easier than the second solution, but not as
    easy as the first :)

    And one more way would be to load the map into photoshop or whatever, and just
    add one dot, save as0001, add another dot, save as 0002,,, etc. then you can
    import the image "sequence" all in one go and bam, it's animated. Gives you
    fine control over teh duration of each part, if you want the course to speed up
    and slow down, you just stretch individual stills to fit... This would not be
    my favorite way, unless the line of dots was going to have to double back over
    itself and get all knotted, like for a comedy bit...

    If you can speak a little bit of french or german, you can look at (french) or (german).
    The software itself as an approximate english translation.
    It can make a video sequence of a line appearing following a road.
