How to create animated GIF animations
Create a new animation via menu
File/New Project....
You can set the special media type 'Animated GIF'.
An GIF animation can have a transparent color. Just enable transparency
at the top of the main form and select the color that is used as transparent:

The transparent areas are displayed as a white/gray checker pattern.
Pro Motion is not a GIF optimizer, but the files that are created should be small
enough. You can change some optimization options in menu
File->Project settings... section GIF.
Generally GIF files become smaller if you use an equal palette for all frames and if as least
as possible colors are used.
The menu Colors contains certain functions to reduce
animation and image colors.
For saving animated GIF files use the corresponding file type from the save animation dialog.
