<h3>Convert DVD to H.264</h3>
<p> <code>ffmpeg -i concat:<i>input_file1</i>\|<i>input_file2</i>\|<i>input_file3</i> -c:v libx264 -c:a copy <i>output_file</i>.mp4</code></p>
<p>This command allows you to create an H.264 file from a DVD source that is not copy-protected.</p>
<p>Before encoding, you’ll need to establish which of the .VOB files on the DVD or .iso contain the content that you wish to encode. Inside the VIDEO_TS directory, you will see a series of files with names like VTS_01_0.VOB, VTS_01_1.VOB, etc. Some of the .VOB files will contain menus, special features, etc, so locate the ones that contain target content by playing them back in VLC.</p>
<dl>
<dt>ffmpeg</dt><dd>starts the command</dd>
<dt>-i concat:<i>input files</i></dt><dd>lists the input VOB files and directs ffmpeg to concatenate them. Each input file should be separated by a backslash and a pipe, like so:<br/>
<code>-i concat:VTS_01_1.VOB\|VTS_01_2.VOB\|VTS_01_3.VOB</code><br/>
The backslash is simply an escape character for the pipe (<strong>|</strong>).
<dt>-c:v libx264</dt><dd>sets the video codec as H.264</dd>
<dt>-c:a copy</dt><dd>audio remains as-is (no re-encode)</dd>
<dt><i>output_file.mp4</i></dt><dd>path and name of the output file</dd>
</dl>
<p>It’s also possible to adjust the quality of your output by setting the <strong>-crf</strong> and <strong>-preset</strong> values:</p>
<p><code>ffmpeg -i concat:<i>input_file1</i>\|<i>input_file2</i>\|<i>input_file3</i> -c:v libx264 -crf 18 -preset veryslow -c:a copy <i>output_file</i>.mp4</code>
</p>
<dl>
<dt>-crf 18</dt><dd>sets the constant rate factor to a visually lossless value. Libx264 defaults to a <a href="https://trac.ffmpeg.org/wiki/Encode/H.264#crf">crf of 23</a>, considered medium quality; a smaller crf value produces a larger and higher quality video.</dd>
<dt>-preset veryslow</dt><dd>A slower preset will result in better compression and therefore a higher-quality file. The default is <strong>medium</strong>; slower presets are <strong>slow</strong>, <strong>slower</strong>, and <strong>veryslow</strong>.</dd>
</dl>
<p>Bear in mind that by default, libx264 will only encode a single video stream and a single audio stream, picking the ‘best’ of the options available. To preserve all video and audio streams, add <strong>-map</strong> parameters:</p>
<p><code>ffmpeg -i concat:<i>input_file1</i>\|<i>input_file2</i> -map 0:v -map 0:a -c:v libx264 -c:a copy <i>output_file</i>.mp4</code></p>
<dl>
<dt>-map 0:v</dt><dd>encodes all video streams</dd>
<dt>-map 0:a</dt><dd>encodes all audio streams</dd>
</dl>
