Platform Differences

The Mac OS and Windows versions of SuperLab 4 are generally the same. Even the experiment files can be moved back and forth. But a few differences remain:

Picture file formats | BMP, GIF, JPEG, PICT, PNG, TIFF, and any file format supported by QuickTime | BMP, GIF, JPEG, PNG, and TIFF
Sound file formats | AIFF, WAV, MP3 | WAV
Movie file formats | MOV, MPG, and any file format support by QuickTime | AVI and MPG
Voice key using built-in sound capability |  | Not available
Emailing an experiment directly from within SuperLab | Not available |

### Moving Experiments Between Macs and PCs

Experiments created with SuperLab 4 or later versions can be moved freely between computers using Mac OS and Windows, but there are two caveats that one needs to be aware of:

- SuperLab for Windows does not support the PICT file format commonly used on the Mac. If you are planning on using an experiment on both platforms, consider saving the pictures using JPEG, GIF, PNG, or BMP file formats.

- MPG is the only movie file format that is supported on both platforms.

For events that use text (e.g. Text, Self-Paced Reading), SuperLab stores font information independently for each operating system.
