Extras for iMovie - Help

What does the Scrolling Credits Pro app do?

The app allows you to easily and quickly add scrolling credits to the videos you make. Apple's iMovie and other popular video editing apps are great for editing your videos, but none of them provide a quick and easy way to add scrolling credits, like you see in professional movies and TV shows, to the beginning or ending of your videos. Now you can with Scrolling Credits Pro!

What devices is it compatible with?

The app is available for both iOS (iPhone/iPad) and MacOS (Mac desktop and laptop computers). Both versions are sold separately and can be purchased from the iPhone App Store and/or the Mac App Store.

How does it work?

It's very easy...

1. Choose from the dozens of backgrounds provided by the app (a solid color, a gradient color, a chroma key green screen, or an image).

2. Enter the text you want to have scroll over the background you've selected. You can even choose to use two columns for your credits, just like the pros.

3. Preview what your scrolling credits will look like, adjusting the font style, font color, font size, and scrolling speed.

4. When you're happy with how everything looks, the app will render and save an HD video clip to your device's Photo Library (Camera Roll) or wherever you specify if running on a Mac. You then run iMovie (or whatever video editing software you use), import the credits clip, and drag it to where you want it to play in your movie.

Everything you do is saved in a "project," so you can always go back and make changes without starting over.

Does it only work with iMovie?

No. The scrolling credit video clips you create can be used with all popular video editing software.

Can I combine one column and two column credits in one project?

Yes, by using "headings." Watch the tutorial video for the app and see the example projects to learn more.

What if the app keeps crashing my iPhone or iPad when trying to save a video?

Rendering video is a very resource intensive process, and mobile devices don't have the same processor and memory resources of a desktop computer, so if you try to scroll large amounts of text, or you have a complex background, the app could crash. If this is happening to you, there are two things to try:

1. Try using some of the different backgrounds (both video backgrounds as well as still image backgrounds) and see if the app crashes with all backgrounds or just certain ones. (Some backgrounds, particularly some of the video backgrounds, are quite complex and could require more memory and processing power to render than your particular device can handle. Try to find a suitable background that still looks good for your project, but doesn't crash.)

2. If necessary, you may need to cut your text into smaller chunks, render those bits individually, then use a video editing app like iMovie to paste them together.

If you have a Mac laptop or desktop, consider getting Scrolling Credits Pro for MacOS (available in the Mac App Store). You can render much larger projects from your computer than you can from a mobile device.

What if the scrolling text in the rendered video appears jerky and not smooth?

This could be the result of competing frame rates. Try rendering the video at slightly different scrolling speeds until you find one that is the smoothest. The number of the scroll speed is shown in parenthesis next to the SCROLL SPEED label, i.e. "SCROLL SPEED (24)." Adjust that speed up or down, one unit at a time, until you find the smoothest results. Usually a scroll speed of 30 is a good place to start and will match up smoothly with most backgrounds, but if not, try different speeds until you find one that is smooth.
