Scrolling Banner - Tutorial

Previously, I have posted a sample on how scrolling banner can be achieved in PowerPoint. Today, I will go through the steps:

First of all, you will need to create a duplicate of the scrolling banner. To do so, right click on the banner, and click Copy.
Next, click Edit > Paste.
Position the original banner on the top of the slide.
Now, place the duplicated banner beside (at the right side) the original ones.
Ensure that there are no gaps in between.
Hold down the Shift key and select both the banners.
Click the Draw button on the drawing toolbar located at the bottom.
Select Group.
Click Slide Show > Custom Animation.
Click Add Effect > Motion Path > Left.
Double click on the added motion path. This will bring up the effect options dialog box.
Uncheck Smooth Start and Smooth End.
Click on the Timing tab.
Click on the Repeat dropdown field and select "Until End of Slide".
Set a speed of your preference. Medium should be good enough.
Ok your way out.
Now here's the tougher part. Basically, what we are trying to achieve here is to have the banner in view first. When the motion path stops, the end position should looks exactly the same as the start position.
Hence, you will need to increase the length of the motion path. How long exactly? It must be the length of one banner.
To do so, select the motion path, then hold down the shift key.
Click on the end point of the motion path, drag it till it is the length of one banner.
Release and preview it in the slide show.
If you can still see minor jerks, do a little adjustment on the motion path until it is perfect.
