A moving road on a Map with After Effect.

  1. How can I draw a moving road on a map with after effect.
    Is there any tutorial on this effect.

  2. If your line following the road map does not backtrack on itself there is a
    simple way to make this effect without much trouble. But, like I said as
    long as the road does not double back on itself anywhere.

    Create a frame with the line tracing the route. Use the original picture
    without the traced route on video track 1A and do a wipe transition to the
    traced route on video track 1B. I created a rudimentary example of this for
    you to see at: http://digitalvideosolutions.com/video/map.wmv What I did was
    take the original map into Photoshop and use a brush to make the route line
    and saved it to a new file. I then took the original and placed it on the
    timeline video track 1A and strectched it out to 5 seconds. I then took the
    traced route and placed it below that one video track 1B. I then chose a
    Wipe transition and made the wipe reveal the traced route to give the effect
    you see in the example.

    If you are using Premiere Pro with single track editing place these end to
    end. You then only have to decide how long this effect will last and stretch
    each picture out to that amount of time. Then choose the Wipe transition. In
    the Effects control make the transition the exact same length as a single
    picture. I know there are more effective ways of doing this in After Effects
    but the overall premise is exactly the same. Either one example replaces the
    other or an overlay with the travel path is wiped onto the original. Using a
    single dash line could be done in After Effects but changing the line to the
    new travel points could be a tedious job. Using the general premise of what
    I did in this example, coupled with an already dashed broken line may be the
    easiest way.
