Briefly is a fun little Mac app for combining piles of photos into a fast-paced video. You simply drag a stack of photos from any other application or folder onto the main window, and it will compile the video. You can sort the photos on the main screen of the application, and add a soundtrack from an audio file or MP3. You can see a quick sample I made on YouTube.

You can set the size of the output movie, but Briefly can also automatically determine the best dimensions based on the size of the photos, and reduce the amount of letterboxing (black bars) required to make them all fit the screen. The only thing it’s really missing, in my opinion, is the ability to set the timing of the transitions.

You can share your videos to the usual email, messages, etc. sources, as well as YouTube and Flickr. In combination with GifBrewery, you can easily make an animated gif out of the resulting movie, which can lead to great fun.

Briefly costs $4.99 US in the Mac App Store, but I happen to have 5 copies to giveaway to my readers. Enter using the form below and winners will be drawn on Tuesday, July 16th at 12pm CST. Residents of Canada excluded, sorry.
