<h3>Create a burnt in timecode on your image</h3>
<p><code>ffmpeg -i <i>input_file</i> -vf drawtext="fontfile=<i>font_path</i>:fontsize=<i>font_size</i>:timecode=<i>starting_timecode</i>:fontcolor=<i>font_colour</i>:box=1 :boxcolor=<i>box_colour</i>:rate=<i>timecode_rate</i>:x=(w-text_w)/2:y=h/1.2" <i>output_file</i></code></p>
<dl>
<dt>ffmpeg</dt><dd>starts the command</dd>
<dt>-i <i>input_file</i></dt><dd>path, name and extension of the input file</dd>
<dt>-vf drawtext=</dt><dd>This calls the drawtext filter with the following options:
<dl>
<dt>fontfile=<i>font_path</i></dt><dd> Set path to font. For example in OSX: <code>fontfile=/Library/Fonts/AppleGothic.ttf</code></dd>
<dt>fontsize=<i>font_size</i></dt><dd> Set font size. <code>35</code> is a good starting point for SD. Ideally this value is proportional to video size, for example use ffprobe to acquire video height and divide by 14.</dd>
<dt>timecode=<i>starting_timecode</i> </dt><dd> Set the timecode to be displayed for the first frame. Timecode is to be represented as <code>hh:mm:ss[:;.]ff</code>. Colon escaping is determined by O.S, for example in Ubuntu <code>timecode='09\\:50\\:01\\:23'</code>. Ideally, this value would be generated from the file itself using ffprobe.</dd>
<dt>fontcolor=<i>font_colour</i> </dt><dd> Set colour of font. Can be a text string such as <code>fontcolor=white</code> or a hexadecimal value such as <code>fontcolor=0xFFFFFF</code></dd>
<dt>box=1</dt><dd> Enable box around timecode</dd>
<dt>boxcolor=<i>box_colour</i></dt><dd> Set colour of box. Can be a text string such as <code>fontcolor=black</code> or a hexadecimal value such as <code>fontcolor=0x000000</code></dd>
<dt>rate=<i>timecode_rate</i></dt><dd> Framerate of video. For example <code>25/1</code></dd>
<dt>x=(w-text_w)/2:y=h/1.2</dt><dd> Sets <i>x</i> and <i>y</i> coordinates for the timecode. These relative values will horizontally centre your timecode in the bottom third regardless of video dimensions.</dd>
</dl>
<dt><i>output_file</i></dt><dd>path, name and extension of the output file.</dd>
