Configuring the Movie Player

The Movie Player Configuration dialog box enables you to change the appearance and behavior of the player. To open the Configuration dialog box, select File > Configuration > Edit. (To load a preexisting configuration set, select File > Configuration > Load.)

The Movie Player displays the Configuration dialog box. This dialog box contains four panes, Core, Sources, Visuals, and Tools, which each offer various options. On each pane, you can select a category and then click Options to view configuration settings.

Saving Your Configuration Settings. To save your configuration settings for future use, select File > Configuration Set > Save as.

Note By default, the Movie Player uses the configuration settings from the file implay.cfg. If you want to store your configuration settings in this file, you should first create a backup copy of the file.

Specifying the Frame Rate

To decrease or increase the playback rate, select Frame Rate from the Playback menu, or use the keyboard shortcut T. The Frame Rate dialog box displays the frame rate of the source, lets you change the rate at which the Movie Player plays the image sequence or video, and displays the actual playback rate. The playback rate is the number of frames the Movie Player processes per second.

If you want to increase the actual playback rate, but your system’s hardware cannot keep up with the desired rate, select the Allow frame drop to achieve desired playback rate check box. This parameter enables the Movie Player to achieve the playback rate by dropping frames. When you select this option, the Frame Rate dialog box displays several additional options that you can use to specify the minimum and maximum refresh rates. If your hardware allows it, increase the refresh rate to achieve a smoother playback. However, if you specify a small range for the refresh rate, the computed frame replay schedule may lead to a choppy replay, and a warning will appear.
