The MKV file format has become widely used for storing and sharing high-quality video content because of its ability to contain multiple audio and subtitle tracks. Converting movies or TV shows into MKV format allows for more flexibility in playback, as MKV players are widely available on various platforms.

Converting a Blu-ray or other video sources to MKV involves not just changing the container format but often also involves encoding or transcoding the video and audio streams to ensure compatibility with various media players and devices. This process can sometimes result in a loss of quality, depending on the settings used, but when done properly, it can maintain high video and audio quality.

Why would anyone convert a Blu-ray (high definition) down to 480p (standard definition)?

Better practice: Keep a 1080p or 720p copy and let your media server transcode on the fly. Never permanently downscale your only source.
