The primary difference between MKV and MKA is that MKV files contain video (typically with audio and subtitles), while MKA files contain only audio.
In-Depth Explanation
Here's a breakdown of the differences:
-
MKV (Matroska Video):
- Purpose: Designed as a flexible container format that can hold video, audio, and subtitle tracks in a single file.
- Content: Typically contains one or more video streams, one or more audio streams, and optional subtitle streams. It can also include chapters, metadata, and attachments.
- Usage: The most common extension for Matroska files containing video.
-
MKA (Matroska Audio):
- Purpose: Specifically designed for audio-only content. It's a container format optimized for storing various audio compression formats.
- Content: Contains one or more audio streams. Can support various audio codecs like MP3, AAC, Vorbis, FLAC, AC3, DTS, PCM, and more.
- Usage: Used for storing music, audiobooks, sound effects, or any other type of audio-only data.
