This is one of the effects I take you through, step by step, in my "Cool Tricks and Hot Tips for Adobe Premiere Elements" book, Dobie, if you're interested.
In fact, I even do a demo of it on the product page at Premiere Elements support site Muvipix.com. (Click the little>>in the lower right of the demo clip to see a brief tutorial.)
The basic principle is that you have two graphics -- one a map and the other the same map but with a line drawn over it.
You place one on top of the other on your timeline, then you keyframe the Crop effect to reveal to the line slowly, as if it is being drawn.
In the book I even show you how to make both maps move, as if you are panning over them, and even how to add an airliner or car graphic over the line.
I strongly endorse Steve's Tips & Tricks book and series.
I use a slight variation of the method that he lists here, but it results in a multi-Layer PSD file from Photoshop. PrE cannot handle a multi-Layered file, and retain those multiple Layers, like PrPro can.
The key is to produce your dotted line with a Transparent Background, but that can be done in Photoshop, or PSElements, or even with the Titler in PrE, though the latter takes a little work.
This one "trick" is worth Steve's whole book, at least IMHO.
Good luck, and happy editing,
Many thanks for your prompt reply Steve. So glad Pre9 has this feature as I am trying to make short videos of our travels.
Love this Adobe Forum. It is so helpful to have someone to refer to when trying to learn this software.
Your Muvipix Guide to Pre9 book is my video editing bible Steve, and very easy to follow for a beginner like me.
I'll put your Tips and Tricks book on my Christmas wish list as this looks great too.
Once again, many thanks......your help is much appreciated.
Many thanks for your prompt reply to my question. Love this forum.....so helpful.
Delighted to learn I can make the dotted line effect with Pre9. I'll give your method a try while I check out Steve's website and put his Cool Tips and Tricks book on my Christmas wish list.
As you said, this "one trick" will be worth the whole book, and I'm sure to learn more as well. I have his Guide to Pre9 book which is my video editing bible and I'm gradually working my way through it and learning to use the many features of Pre9. I've yet to burn my first DVD, so that will be the next step on my learning curve.
Thanks again....your help is much appreciated.
I guarantee that you will love the whole book.
Unless it has been added to later versions of PrE, one Effect that I lkie (in lieu of Crop) is Linear Wipe, but I'm using that in PrPro, and not have it in my older PrE.
One little variation, that might be interesting is to do some of the base animation on Layers in PS/PSE and then Save those Layers as PSD Images - one Layer = one Image. With PS and PrPro, I just do Layer Comps, but then can bring in the Layered PSD's, Unflattened.
Good luck, and have fun,
Thanks for supporting the books, Faye! I'm thrilled to hear that you're finding them helpful!
