If you’ve not played around with still motion videos — videos where photos are shown only for a fraction of a second — you might give it a try. They’re lots of fun.

Eternal Storms Software’s Briefly 1.0 for Mac OS X lets you create still motion videos with just a few clicks and share them on popular video services .

You can import photos from your hard drive, flickr or Instagram and add a soundtrack from your iTunes library. Briefly then does the rest for you. The software output video up to 1080p. Or it can choose the best resolution automatically based on the smallest photo. This way, it can reduce or eliminate the occurrence of black borders around the photos.

If the chosen (optional) soundtrack is longer than the duration of the final video, the soundtrack will automatically be faded out at the end to make it a smooth experience for viewers and seamless for users of Briefly. After the video is created, it can be posted to services such as YouTube and Vimeo, as well as Facebook and flickr — right from within the Eternal Storms Software app.

Briefly requires Mac OS X 10.6 or higher. It’s available exclusively on the Mac App Store (http://tinyurl.com/knv32t4) for the introductory price of US$$4.99 (the regular price is $7.99). A free 15-day trial is available at the Eternal Storms web site (http://eternalstorms.at).
