What is MKV?

MKV

MKV (Matroska) is a versatile container supporting virtually any audio codec including AAC, MP3, Vorbis, Opus, FLAC, and DTS. Extracting audio means demultiplexing—isolating audio tracks from video and subtitle streams. This preserves original audio quality and codec. MKV can contain multiple audio tracks in different languages or formats simultaneously.

  • MKV combines video and audio streams in a container, allowing audio track extraction
  • Contains separate audio track easily extracted to AIFF format
  • Video stream discarded—only audio codec and bitrate matter

What is AIFF?

AIFF

AIFF stores pure audio waveform data without visual components. Video requires image frames synchronized with audio. AIFF provides the audio track—creating video also requires visual content. You'd need to combine AIFF audio with an image sequence or video source.

  • AIFF contains pure audio data requiring video track addition for video output
