StackMotion is a new photo editing tool from Flambe Studios, the makes of PicPlayPost and PopAGraph that allows you to combine photos, videos, text and music. The app uses layers to let you create really unique projects.
StackMotion has two main screens -- the playback screen that allows you to view your project as you build it and the editing screen, which is where you swap out your media and tweak it to your satisfaction. The editing screen is where you will spend most of your time, and it is chock full of options for editing your project.
The first step in creating a project is choosing the correct media for your background image and your foreground image. The foreground is a static image, but the background can be dynamic with the option to add a panoramic photo, a slide show or a video clip. Once you have the media selected, you can add them to your project by importing them from the camera roll or taking them live using the camera.
As you would expect, the background image becomes your canvas, while the foreground image can be masked to overlay neatly on the background. You also can add text to the project and music if you prefer. The building of the project has the feel of the a non-linear editor like iMovie, but it is much more simple with a short timeline and only one media element per type, i.e., one block of text, one track of music, etc.
When you are adding each type of media, the StackMotion app has a few editing options that allow you to change the text, flip your photo, apply filters, and so on. You also can set the text timing so it appears in the beginning, end or is always on the screen. An undo button allows you to correct mistakes, while a clear button lets you start over. When you are done editing, you can share your project via social media, upload it to a vide service like YouTube, publish it to Tumblr or export it to your photo roll.
Overall, StackMotion was enjoyable to play with as it allows you to do more than just prettify a photo. The ability to use a slideshow, a video clip or a scrolling panorama as your background adds a new dimension to the creation process. My only complaint with the app is a minor one -- when you edit an element like text and hit the "Done" button, the app brings you to the playback screen to review your project and autoplays the clip, which can be annoying when you are trying to edit quietly. I'd rather stay in editing mode and have the option to review by manually pressing play when I am ready.
StackMotion is available for US$1.99 from the iOS App Store.
