Apple Motion Interface
Trapcode Starglow has been ported to run as an FX Plug in Motion 3.0 and later. While the plug-in may run in earlier versions, we do NOT recommend running Starglow in Motion 2.1.2 or earlier versions, due to stability issues.
Accessing Starglow
The Starglow Filter is accessible from the Library tab under the Filters > Trapcode category.
Interface
Trapcode Starglow offers nearly the same controls as the After Effects version, except for the Colormap presets under the Presets menu.
Presets
Starglow does not feature built-in presets for the plug-in as explained in the Main section. This is a limitation of Apple's FX Plug format.
Note: Presets are now available as Favorites that you can drag and drop from the Library > Favorites tab. Simply drag and drop the preset onto the target layer in the Timing panel or into the preview.

Colormap Presets
The Colormap presets are not available in Motion (as explained in the Colormap section). Instead, load a Favorite to access a number of presets in Motion.
Floating-Point Support in Motion
Edit > Project Properties...and then click the Bit Depth pop-up to change the value to 32 Bit (Float). Click the Dither button if you plan to output to lower-bit-depth formats.

Pre-Grouping
In Motion, Starglow cannot naturally expand the bounds of Text Objects or other objects that are smaller than the project size. This causes clipping of the glows or glints, which is rarely the desired result. To avoid this issue, you will need to create a Group and set the Fixed Resolution to the project output size or larger.

Here is a preview of the Motion Timeline with the Fixed Resolution tag set to off.

Clipping in the Preview | Fixed Resolution off

To avoid the clipping issue, simply click the Fixed Resolution button on for the selected group where Starglow is applied.
