1. Why Remuxing MKV Instead of Transcoding?

Remuxing means taking the audio and video streams needed from one container to another container. It is a lossless process that the original audio and video data is kept untouched. The opposite to remuxing is transcoding, which means the conversion of one encoding to another. The source data is changed during the transcoding, hence a lossy process.

Many people now choose remuxing MKV over transcoding because 1. Remuxing preserves the original quality without any loss; 2. Remuxing shortens the conversion time significantly.

If you are planning to remux some of your MKV files, follow carefully the tips and steps in the next parts.

2. Remux Tips – Ensure Zero Quality Loss

Many converter programs allow MKV remuxing if the conversion meets the following criteria.

  • Use the same encoder as the source encoder, e.g. H.264;
  • Do not change any other parameters, such as resolution, aspect ratio, bitrate, etc.;
  • Do not edit the file before conversion (selecting audio tracks is allowed);
  • The MKV file can only be remuxed to MP4 and MOV containers (If it is an H.264 encoded MKV file, M4V and MTS are also among the output options);

It won't be difficult to meet these remux requirements, not if you use the right remux software. The next tutorial will show you how to remux MKV with the best remuxer.
