This program was designed to provide you with a solution for an old issue: inability to play SWF files on various models of mobile devices or popular applications. You can use this utility to convert SWF files to a wide variety of video formats that are compatible with apps like Final Cut Pro or Adobe Premiere and many media gadgets, such as iPhones, iPads, HTC mobile phones, etc.
You can import and convert one file at a time as the app doesn't offer you support for batch processing. The program lets you choose between various output profiles, watermark the input file if necessary, and trim or crop the SWF file. Once you finish configuring the output settings according to your needs, you can select the proper destination folder and click the Capture button.
The application also comes with a built-in video player where you can preview the input files and check if the alterations (trim, crop, and watermark) were made on point.
However, this program isn't the best there is. Besides the fact that it's a bit pricey, the utility doesn't offer you support for batch processing and an option to extract soundtracks from videos, and it occasionally crashes.
Hence, I'd say you should look for a different SWF converter as this one isn't as efficient as it's being stated on the homepage of the developer.
