Convert sfd to png

What is the difference between .sfd and .png?

Description: The SFD file format (Sofdec Dreamcast Movie) is a proprietary video file format developed by CRI Middleware specifically for use on the Sega Dreamcast gaming console. This format was used to encode and store video data for playback within Dreamcast games, allowing developers to include high-quality pre-rendered video sequences and cutscenes. The SFD format is optimized for the Dreamcast's hardware capabilities, ensuring smooth playback and efficient storage use on the console's limited media capacity.; A PNG file is an image file stored in the Portable Network Graphic (PNG) format. It contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations. PNG files are commonly used to store graphics for web images.
