Draw a train trace over a flying shot

Dec 3, 2013 12:31 PM

Hi guys,

 

here is my shot.

http://youtu.be/Lbw-aD672A4

 

 

Basicly what i want to do is to draw a line that represents a train trace over the ground. Any clue about how to do it? I started using the camera tracker and creating a null and a camera and then got lost.

 

So thanks to anyone´s help!

    First, that's a very long shot. I'd work with just the part you want.

     

    Second, you should stabilize the footage first then render a DI (digital intermediate) to a lossless or nearly lossless codec.

     

    Then you try a 3D camera track. At a mid point in the shot set a ground plane and then add a plane and a camera.

     

    Now just draw a mask line on the ground plane and apply stroke. That's about it. There are lots of tutorials but I'd look first at Adobe TV for the basics.
