Apply an effect to the leading edge of a stroke
Hello
I am trying to animate a logo. I have what I want for the “reveal” of the logo, but I want a little more punch and so I was hoping someone can tell me how to have an effect follow the leading edge of the stroke effect I have applied, or if it is even possible.
I was hoping to cause the edges to glow as it travels and possibly emit some particles or light blur type effect. I have seen the idea that I am looking for before, but I can’t remember where. If I remember or find it I will post a link as an example.
Any ideas would be much appreciated.

Have you tried duplicating the layer, and then changing the stroke on the duplicated layer to just be the length of the leading edge of the original stroke?
Not sure exactly what youre trying to do, but thats what I usually do.

You can also duplicate and delay the stroke layer by 1 frame and then use track matte to only reveal the tip of the stroke.
To apply a trail to the stroke, I would first motion track the tip of the stroke and then apply the motion to a light layer.
Finally set Trapcode Particular to emit particles from the light layer to get the trail. -
Hello
Thanks. Those are ideas that I didn’t think of.
I was thinking about the tutorials that I have watched at the cow and I realised that the particle playground on fire by Maltannon had my solution for a possible way of doing it. I used time difference and found the leading edge of my stroke that way.
I used it to apply a radial fast blur and it looks like the logo is being written by light, kinda. I am thinking that I will try putting particles on it with trapcode and see what effects I can get on it. The time difference is a cool way to find a moving edge.
If there are any other ideas, please post them, I might find one is more elegant or efficient than what I came up with.

Pardon the intrusion, but is this the same John Felt that use to be a tech on the Trinity forum?
