           <h4>Important caveat</h4>
-          <p>It may not be possible to rewrap a file's contents to a new container without re-encoding one or more of the streams. Some containers can only contain streams of a certain encoding type: for example, the .mp4 container does not support uncompressed audio tracks. (In practice .mp4 goes hand-in-hand with a H.264-encoded video stream and an AAC-encoded video stream, although other types of video and audio streams are possible). Another example is that the Matroska container does not allow data tracks; see the <a href="#mkv-to-mp4">MKV to MP4 recipe</a>.</p>
