LazyFallback – Creating Fallbacks For Flash Files Quickly
For creating a highly animated banner, Flash is probably still the best solution. However, it is not completely supported anymore; some users prefer not to install it and the popular iOS doesn't have it at all.
So, creating fallbacks for Flash banners is a very good idea to make sure you display a visual for everyone and, LazyFallback -a free Adobe AIR application– handles this process well.
By simply drag 'n' dropping any number of SWF files to the application, it generates JPG alternatives for each of them quickly.
LazyFallback is a simple application which doesn't have many setting and only 2: defining the moment of the Flash animation for fallback generation and quality of JPGs.
P.S. What would possibly be better is the ability to get animated GIFs besides the JPGs.
