I got a good one here PLEASE READ!
First I drew a shape with a bezier line.
Second I traced that shape with a bezier mask.
Third, I added a stroke filter effect.
On a 16 second time line I input the END values as 0 at the beginning of the time line and 100 at the end of the time line.
This gives me a line being drawn out. Its real simple I know but what I am trying to do is attach a camera to the point of the line that is drawing and follow it around. Any ideas how to do that. I tried attaching a NULL object to the shape mask but that doesnt really work. Or at least I think I did it right. Anyway is there an expression or another way of doing this? How can I add a camera to a line and animate it to follow the line not just run on it?
Cheers!

You must create a motion path from the mask. Might require retracing the shape again. Express or parent the null to the motion path and parent the camera to the null.
Wait a few hours and you will probably get more and better advice. The wonks are till waking up on the West Coast.bogiesan

The Wonks HAHA! Thanks I will try that. Hopefully I can get more feed back though

When you say Motion path do you mean Motion Sketch?
-
You can copy and paste between paths drawn with the pen tool, and the motion path of your layer.
select a path (mask shape) in your comp, go edit/copy. click the ‘position’ parameter of you layer in the timeline, and go edit/paste to paste it in as a motion path.
hope that makes sense.

as for making camera follow you ‘end point’ keyframes – maybe use the expression pickwhip to link from you camera position up to your ‘end point’ value in the animated stroke.
-highlight the camera’s position keyframe track, go animation/add expression. the pickwhip is the little @ symbol thing
Im just guessing here – might be worth a try
-
Yeah I tried to pick whip the null objects position to the mask’s end point but it just made the null object move in a weird way. It didnt follow the path.
-
hmm.. I had something similar once where after pasting a path into the motion keyframe track, it didn’t follow properly. It was following the right motion shape, just not over the actual path. It turned out i had to put my anchorpoint in the right place on the layer that was following first.

I have also tried to do the motion sketch, thats not working either unless I am doing something wrong.

Umm, no.
All you need is a layer with a motion path on it. You can create the path in many ways, easy to just draw it. It’s called a motion path because it’s the path your object will follow.
You could also create a null and move it around, setting keyframes and manipulating the Beziers. This path is the motion path. You might be able to coy the mask shape and paste it into the position parameter on the null.
