DemoForge vs. Flash: format comparison

DemoForge Studio can save your clips in both DemoForge proprietary and Macromedia Flash formats. DemoForge format is much more compact and provides better visual quality; Macromedia Flash format is wide-spread, thus making it seem appealing to use for software tutorials.

Macromedia Flash is sometimes used for creation of animated clips by capturing data from the computer screen. Being a popular multimedia format, Macromedia Flash is nevertheless not designed for such use.

Due to the technical limitations of the SWF format, clips saved in Macromedia Flash format are usually quite large in size (up to 10 times bigger than a similar DemoForge clip). Playing Macromedia Flash clips may require large amounts of memory, proportional to the movie length. In some cases it can get as much as a 100 megabytes for a few minutes of movie. They often work around this problem by reducing the number of frames displayed per second, which negatively affects visual appearance of the movie. Often a movie is substituted with a slide show, brightened by transition effects.

A maximum length of an SWF movie is limited depending on many conditions; it can be anywhere up to a few minutes, depending on the information being capturing.

DemoForge format does not have those limitations. DemoForge clips are compact, natural, do not have any visual artefacts while flipping frames, and have smooth mouse movements.

DemoForge format provides a 100% playback quality combined with minimal requirements to the Internet connection speed, memory, and CPU speed of your end-users' computers.
