    I’ve seen it a bunch (in all sport related shows) a arrow draw on and follow the ball. I’m trying to do something for a golf show (instructional) where the arrow follows the arc of the ball and follows the ball as it bounces (small arcs). The arcs are wider in the air and thin when they touch the ground. My first thought was to create each arrow in Illustrator and mask it. But this looks bad and I was wondering if there was a better way of doing this. Would this be easier to do with a motion path and 3d stroke or particular? It seems so simple but it’s driving me crazy.

    Any suggestions or anyone know what program or plug in they use to do this.

    Thanks!!!

    What if you setup a motion tracker to track the ball…

    That’s a great idea but the ball is almost impossible to see. It was shot by lots of trees with lots of light from behind them. We actually threw out the idea of using the live action due to too much camera movement.

    I basically have a still picture of the golfer with the hole about 15 yards away and I’m animating the arrows over showing the path the ball took or should have taken. I guess the problem for me is how to animate the line and get a good depth of feel since the ball is being shot away from us. I tried masking a line, but it looks bad.

    it sounds like you need to make an arrow shaped solid by what ever meas you feel best, mask photoshop, illustrator, etc, place it in a composition, add a camera, make the layer 3d, and animate as you see fit, a 3 point line shouldnt be to bad as long as it all smothed and rounded
