Virtix today announced the availability of iBubble for iMovie, a collection of 13 titles for Apple’s movie editing software. iBubble contains “Thought Bubbles” and “Speech Bubbles,” which are cartoon-like images that allow users to make it look like a person is speaking certain words or is thinking certain thoughts. The software also contains “Labels with Arrows,” so users can place the labels and direct the arrows to certain objects in the movie, and “Plain Text,” titles, which can be placed anywhere on the screen. Virtix iBubble for iMovie works with iMovie 2 and iMovie 3, and is priced at US$24.99. A Web page with sample images is available from the Virtix Web site.
