Need to batch convert .SWF to .PNG

It seems odd that I am having a difficult finding an answer to this issue within Adobe when a dozen programs on the market will do the job; I thought it would be integrated in Animate or Bridge, but searches come up empty. I have THOUSANDS of .SWF files to convert, the vast majority are static; I know that animations and interactive files will be treated differently. 

Is there a way to batch convert large volumes of .SWF files into .PNG format within Adobe's products, or do I just buy SoThink, reaConverter, or some other product?

Thanks for the help,

Greg
