How to do a ‘circle a job ad’ effect?
Hi,
I need to have a something on the screen, then have an effect of someone drawing an oval around it in pen, as if they were quickly drawing a circle round a job ad.
(but with no hand or pen being seen obviously, just the animated circle).How would I do this?
Thanks

Did this recently. Very easy for a basic pen stroke.
1) Use the pen tool to draw a path around the part of the image you want circled.
2) Apply the Stroke effect and adjust the color, brush hardness, brush size, etc. to taste. Make sure “Paint Style” is set to “On Original Image.”
3) Go to the time where you want the pen stroke to start. Set the Start property to 100% and apply a keyframe.
4) Go to the time where you want the pen stroke to finish. Set the Start property to 0%.Now if you want more detail in the pen stroke, I would suggest going through Aharon Rabinowitz’s tutorial on animating signatures. The same techniques introduced in the tutorial should help with what you’re doing.

Thanks!
I will try this at the weekend and let you know how I got on.
Out of interest, how does After Effects know to let it draw itself out, and not fade it all in?Sorry, I’m quite new to this.

That’s what the Start property is for. At 100%, there’s no stroke. At 0% the stroke stretches from one end of the path to the other. See the tutorial for more details. Or, look up the Stroke effect in the manual or online.
