Moho animations can be exported in a number of different formats. These can be categorized as movie files, Flash files, or still images.
Most often, you'll export an animation as a movie file. You have two choices:
QuickTime (Windows and Mac OS): QuickTime is a very flexible format for working with movies. We generally recommend using QuickTime with the Sorenson 3 codec for the best combination of low file size and quality. If you choose QuickTime, Moho will also export the soundtrack (if you have applied one to the animation). On Windows, if you don't see QuickTime as an option, then you need to download and install QuickTime. You can get it for free here.
AVI (Windows only): On Windows you can also export movies in AVI format.
When exporting a movie, Moho will include an alpha channel if the codec you're using supports it. This makes it possible to composite Moho movies with other media in a video editing program.
If you're using QuickTime, set the color depth to "Millions of Colors+". The "+" is QuickTime's indication of an alpha channel. The codecs that support this include Animation, None, PNG, TGA, and TIFF.
AVI on Windows doesn't include any built-in codecs that support alpha channels. However, at least one such codec does exist, and you can download it for free - the Huffyuv codec.
Moho can also export Flash files in SWF format. Flash is a common vector animation format on the web. When exporting Flash, Moho will also include the soundtrack (if any) if the soundtrack is in MP3 format. If you plan on exporting Flash files, it is important to read the section about optimizing for Flash here.
Finally, you can export an animation as a sequence of numbered still images. This option is not used very often, but sometimes for certain post-processing tasks, you may prefer to work with a sequence of separate still image files. You can choose between JPEG, BMP, Targa, or PNG.
