MKV

Matroska Video file format

MKV (Matroska Video File) is an open, flexible multimedia container format designed to store video, audio, subtitles, and metadata in a single file. It is widely supported by media players like VLC, MPC-HC, and tools such as MKVToolNix for editing and muxing. The format uses EBML (Extensible Binary Meta Language) for its structure, enabling advanced features like chapter support, multiple audio tracks, and seamless streaming capabilities.

AAC

Advanced Audio Coding

AAC (Advanced Audio Coding) is a digital audio coding standard designed to provide high-quality audio at lower bitrates compared to MP3, making it a popular format for streaming and storage. It is widely supported by platforms like iTunes, YouTube, and Android devices, and can be created or edited using tools like Audacity, FFmpeg, and Adobe Audition. The format uses advanced compression techniques, such as perceptual noise shaping and temporal noise shaping, to optimize audio quality while maintaining efficient file sizes, and it supports multiple channels for surround sound and metadata for enhanced functionality.
