What happens when you import a Toon Boom Studio animation set into Flash MX?

When you import a Toon Boom Studio™ animation set into Macromedia® Flash™ MX, TBSi:

Preserves all sound element layers, if you choose to import sound. (Importing into a movie only.)
Converts all unique Toon Boom Studio™ assets into symbols in the Macromedia® Flash™ MX Library. The symbols are organized according to their scene, element and file name.
Places all sounds and bitmaps in the root level of the symbol Library. TBSi also adds the scene name to the name of bitmaps.
Calculates the position, size and rotation of symbols derived from elements that are changed over time by pegs. (Importing into a movie only.)
Expands all Toon Boom Studio™ Media elements (links) into their individual symbols.
Calculates the value of color transform effects for each frame. You can see the color value of each symbol in the Properties panel, Color drop-list.
Calculates the visual result of clipping effects frame-by-frame. Clipping and mask layer symbols appear in the Library, as well as unique symbols for each frame, which represent the cumulative effect of the clipping and mask layers.

There are a couple of issues you should consider when importing your animations:

TBSi does not import the scene background color.
Macromedia® Flash™ MX does not display multiplicative color transform effects with a value greater than 1. If you want to create a multiplicative effect greater than 1, you must re-create the effect in Flash.
Macromedia® Flash™ MX does not import clipping effect elements that include other clipping effect elements.
