Create a Gradient Fill
This tip requires using a second program to get started. I use PowerPoint and create a white-to-gray gradient box. In PP I just draw a rectangle and then right-click and select Format Shape from the context sensitive menu. I then adjust the sliders and colors to get the gradient I want. I’m using gray and white because I want to apply this to various colors in Camtasia. I will then do a screen capture to to copy this rectangle with SnagIt but you could also export the slide as a .png. Once I have the gradient in SnagIt I use the Share tab to send it over to Camtasia Studio and then I add it to my asset library so it’s always available.
Then I put my white-to-gray gradient rectangle over top of my simple rectangle. I adjust the opacity to 30% and resize it to match my callout in Camtasia. Once I have the overlay sized and looking the way I want, I group the two items together. This way I can resize them if needed with a simple click and drag.
