What is MKV?
MKV, or Matroska Video, is a flexible and open-source multimedia container format. It can hold an unlimited number of video, audio, subtitle tracks, and metadata in a single file. MKV is popular for high-quality video content because it supports multiple codecs and advanced features like chapters and multiple audio tracks. It’s widely used for HD videos, movies, and TV shows due to its versatility and rich feature set.
What is AVI?
AVI (Audio Video Interleave) is a multimedia container format developed by Microsoft. It stores both video and audio data in a single file, allowing synchronized playback. AVI files support multiple codecs but tend to have larger file sizes compared to newer formats. It was widely used for video playback on Windows but is now somewhat outdated due to limited compression efficiency.
