<h3>Create GIF</h3>
<p>Create high quality GIF</p>
<p><code>ffmpeg -ss HH:MM:SS -i <i>input</i> -filter_complex "fps=10,scale=500:-1:flags=lanczos,palettegen" -t 3 <i>palette.png</i></code></p>
<p><code>ffmpeg -ss HH:MM:SS -i <i>input</i> -i palette.png -filter_complex "[0:v]fps=10,scale=500:-1:flags=lanczos[v],[v][1:v]paletteuse" -t 3 -loop 6 <i>output</i></code></p>
<p><code>ffmpeg -ss HH:MM:SS -i <i>input_file</i> -filter_complex "fps=10,scale=500:-1:flags=lanczos,palettegen" -t 3 <i>palette.png</i></code></p>
<p><code>ffmpeg -ss HH:MM:SS -i <i>input_file</i> -i palette.png -filter_complex "[0:v]fps=10,scale=500:-1:flags=lanczos[v],[v][1:v]paletteuse" -t 3 -loop 6 <i>output_file</i></code></p>
<p>The first command will use the palettegen filter to create a custom palette, then the second command will create the GIF with the paletteuse filter. The result is a high quality GIF.</p>
<dl>
<dt>ffmpeg</dt><dd>starts the command</dd>
<dt>-ss <i>HH:MM:SS</i></dt><dd>starting point of the gif. If a plain numerical value is used it will be interpreted as seconds</dd>
<dt>-i <i>input file</i></dt><dd>path, name and extension of the input file</dd>
<dt>-i <i>input_file</i></dt><dd>path, name and extension of the input file</dd>
<dt>-filter_complex "fps=<i>frame rate</i>,scale=<i>width</i>:<i>height</i>,palettegen"</dt><dd>a complex filtergraph using the fps filter to set frame rate, the scale filter to resize, and the palettegen filter to generate the palette. The scale value of <i>-1</i> preserves the aspect ratio</dd>
<dt>-t <i>3</i></dt><dd>duration in seconds (here 3; can be specified also with a full timestamp, i.e. here 00:00:03)</dd>
<dt>-loop <i>6</i></dt><dd>number of times to loop the gif. A value of <i>-1</i> will disable looping. Omitting <i>-loop</i> will use the default which will loop infinitely</dd>
<dt><i>output file</i></dt><dd>path, name and extension of the output file</dd>
<dt><i>output_file</i></dt><dd>path, name and extension of the output file</dd>

<p>Simpler GIF creation</p>
<p><code>ffmpeg -ss HH:MM:SS -i <i>input</i> -vf "fps=10,scale=500:-1" -t 3 -loop 6 <i>output</i></code></p>
<p><code>ffmpeg -ss HH:MM:SS -i <i>input_file</i> -vf "fps=10,scale=500:-1" -t 3 -loop 6 <i>output_file</i></code></p>
<p>This is a quick and easy method. Dithering is more apparent than the above method using the palette* filters, but the file size will be smaller. Perfect for that "legacy" GIF look.</p>
