River past Animated GIF Booster Pack is an add-on pack, which adds the ability to output Animated GIF and FLC files to certain River Past and HeavyMath video software.
This is the easiest way for web masters to create animated thumbnails for your video library. Animated GIF is supported by all web browsers, with no additional installation required, so your visitors can get a taste before he gets asked to download the plug-in's required by your file format, and before the large full-length video is downloaded.
Easy of Use
Simply install the booster pack. "Animated GIF" and "FLC" will appear as "Output Format" options. You have the control over size and frame rate.
