## Event Type
Movie

The Movie event type lets you select and play movie, sound, and MIDI files. You can select a single file or have the event pick a file from a stimulus list. You can also have the movie played at different locations, in random or sequential order. The supported file formats are:

- Mac OS: MOV, MPG, MP3, WAV, AAC, MIDI, and any file format supported by QuickTime.

- Windows: AVI, MPG, MP3, WAV, and MIDI. SuperLab requires a video card that supports DirectX 9.0 and VMR 9 (Video Mixing Renderer).

| The Event Editor can be resized. This can come in handy if you want to see a larger thumbnail of your movie.

There are two main views in the Movie event type: Settings and File Info. The File Info view provides information about the selected file. If the event uses a stimulus list instead of a single file, no information is displayed.

In the Settings view:

- Click on the Use popup menu to select whether this event uses a single file or a stimulus list. If you select a single file, a thumbnail of the movie will be displayed. You can resize the Event Editor to see a larger thumbnail.

- Click on the Preview button to see how the movie will be played to participants. SuperLab will open a window that covers the entire screen just as it does when running an experiment. The Preview button is not available if you use a stimulus list or if a movie file has not been selected.

- Click on the Play button to have SuperLab play the movie in place (without opening a window that covers the entire screen).

- Click on the Show grid checkbox to have SuperLab display a grid the next time you click on Preview. The grid can be useful when positioning a movie. The grid lines are 50 pixels apart and are displayed only when previewing from within the Event Editor; they are not shown when running an experiment.

- Click on the Settings button have another dialog appear and set the various options that are available; more about that below.

### Movie Settings

When you click on the Settings button, another dialog appears that provides a range of options for controlling the position and size of the movie as well as other movie playing options such as when it should stop playing. The Position and Size tabs are identical to the ones for Picture File events.
