Pros: It is free Cons: The output AVI files are HUGE and this is an understatement. I am still puzzled how a 250kb swf animation will turn into a 1/2 GIGABYTE AVI movie. This wasn't a onetime occurence but similarely occured with every other swf file I tried to convert. Changing frame rates and output file options did not solve the problem but often resulted in double framed, oddly skewed output videos. It may work with very tiny or rudementary swf files, but if you try to use this program for converting involved swf animations, good luck!
