Convert AAC to MKV
What is AAC?
AAC
AAC is audio-only codec without visual components. Video requires frame sequences with visual data. AAC lacks video streams—creating video from audio requires adding visual elements like album artwork, static images, waveform visualizations, or spectrum analyzers. This requires video editing software combining audio with generated visuals, not format conversion.
- AAC contains pure audio data requiring video track addition for video output
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 AAC format
- Video stream discarded—only audio codec and bitrate matter
