What is the difference between .swf and .hevc?

Description: An SWF file is an animation created with Adobe Flash that can be played by Flash Player or with a web browser that has the Flash plugin installed. It may contain text, vector and raster graphics, and interactive content written in ActionScript.; The High Efficiency Video Coding (HEVC) file, commonly known by its file extension .hevc, represents a video compression format designed to substantially improve coding efficiency compared to its predecessor, H.264/AVC. Aimed at enabling higher resolution video content such as 4K and 8K, HEVC is adept at maintaining high-quality video at roughly half the bitrate, significantly reducing file sizes without compromising on visual fidelity. This efficiency makes HEVC particularly valuable in streaming media applications.
