This must match the naming convention used! The regex %06d matches six-digit-long numbers, possibly with leading zeroes. This allows the full sequence to be read in ascending order, one image after the other.<br/>
The extension for TIFF files is .tif or maybe .tiff; the extension for DPX files is .dpx (or even .cin for old files). Screenshots are often in .png format.</dd>

<p><i>Notes:</i></p>
<p>If <code>-framerate</code> is omitted, the playback speed depends on the images’ file sizes and on the computer’s processing power. It may be rather slow for large image files.</p>

<p>You can navigate durationally by clicking within the playback window. Clicking towards the left-hand side of the playback window takes you towards the beginning of the playback sequence; clicking towards the right takes you towards the end of the sequence.</p>
