Description: Animated Portable Network Graphics (APNG) is a file format which extends the Portable Network Graphics (PNG) specification to permit animated images that work similarly to animated GIF files, while supporting 24-bit images and 8-bit transparency not available for GIFs. It also retains backward compatibility with non-animated PNG files.; AVCHD (Advanced Video Coding High Definition) is a file format designed for recording and playing back high definition video. It is commonly used in digital camcorders and cameras for capturing HD footage. AVCHD leverages the MPEG-4 AVC/H.264 video compression codec, which efficiently reduces file sizes while preserving high-quality video resolution, and supports both Dolby AC-3 and linear PCM audio codecs for high-quality sound.
