# Why use this command?
MKV is the Swiss Army knife of containers. Convert FLV to MKV to modernise your file while keeping the flexibility to add more tracks later.
# Parameter Explanation
The command takes the video/audio streams from the FLV file and wraps them in a Matroska (.mkv) container. This is usually very fast.
