<h3>Rewrap DV video to .dv file</h3>
<p><code>ffmpeg -i <i>input_file</i> -f rawvideo -c:v copy <i>output_file.dv</i></code></p>
<p>This script will take a video that is encoded in the <a href="https://en.wikipedia.org/wiki/DV">DV Codec</a> but wrapped in a different container (such as MOV) and rewrap it into a raw DV file (with the .dv extension). Since DV files potentially contain a great deal of provenance metadata within the DV stream, it is necessary to rewrap files in this method to avoid unintentional stripping of this metadata.</p>

<dt>-f rawvideo</dt><dd>this tells FFmpeg to pass the video stream as raw video data without remuxing. This step is what ensures the survival of embedded metadata versus a standard rewrap.</dd>
<dt>-c:v copy</dt><dd>copy the DV stream directly, without re-encoding.</dd>
<dt><i>output_file.dv</i></dt><dd>tells FFmpeg to use the DV wrapper for the output.</dd>
