-            This must match the naming convention actually used! The regex %06d matches six digits long numbers, possibly with leading zeroes. This allows to read in ascending order, one image after the other, the full sequence inside one folder. The extension for TIFF files is .tif or maybe .tiff; the extension for DPX files is .dpx (or eventually .cin for old files).<br/>
-            The showing speed depends on the image’s file size and on the computing power. It is usually too slow, yet you can visualise immediately the moving images without having to recode and remux into a new file.<br/>
-            You can click into the visualisation window to jump: to the beginning on the left side, to the on the right side, and to every other position proportionally in between.</dd>
