Animation Formats

Avi

This format can be read and written only under Windows. Using QuickTime, AVI animations can also be used on the Macintosh, depending on the codec. When using AVI animations as textures, only the first video track is evaluated; all others (e.g. music) are ignored. If the first video track contains data other than images these are also ignored.

Only 24-bit formats are supported. If you have selected AVI System and the message 'Unable to write file' appears it is most probably caused by a codec which does not support 24-bit data (such as Microsoft RLE).

QuickTime

To use QuickTime under Windows, ensure that QuickTime is installed on your computer. You can download a QuickTime installer from www.apple.com/quicktime.

When using QuickTime animations as textures, only the first video track is evaluated; all others (e.g. music or QuickTime VR) are ignored. If the first video track contains data other than images these are also ignored.

All codecs that are installed in the operating system are supported. Alpha channels are integrated directly into the animation only if the compressor supports this. For the QuickTime format these are the compressions Animation and None (i.e. uncompressed). In both cases, the number of colors must be set to Millions of Colors+.
