Convert FLAC to MKV
What is FLAC?
FLAC
FLAC is audio-only codec without visual components. Video requires frame sequences with visual data. FLAC lacks video streams—creating video from FLAC audio requires adding visual elements like static images, album artwork, or animated visualizations. This requires video editing software combining lossless audio with generated or imported visuals.
- FLAC contains pure audio data requiring video track addition for video output
- Linear prediction compression maintains bit-perfect audio reproduction
- Modern format—requires up-to-date software for compatibility
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 FLAC format
- Video stream discarded—only audio codec and bitrate matter
