Convert sfd to avif

What is the difference between .sfd and .avif?

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.; It is an image compression codec file with the same quality as .jpeg, but that is ten smaller. It supports HDR (High Dynamic Range). SDR (Standard Dynamic Range), and WCG (Wide Color Gamut) images. Also, it contains both the image sequences and image items. The only pitfall is that a few applications support it.
