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.
