Issue with Glow filter in Motion 3
on Jun 1, 2007 at 11:08:45 pm

Hi,

I'm having a issue with Motion 3 and its little nice Glow filter.
The composite is a Text in a 3D space and GLow filter is added to the Text (not the group)
Issue is that the Glow radius is cut off like if it is in a Box.

Now I have not found a Crop box to check or uncheck, so what is the issue and how do I fix this?

Thank you.

Heya,

Unfortunately, some filters in Motion, like Glow, don't grow the size of the object they're applied to. The easiest way to get around it is this:

1. Nest the text in a new 2D group (located at the same place as the text).
2. In the Group tab of the Inspector, enable Fixed Resolution for the group. This tells the group to be a particular size. By default, this size will be the size of the project.
3. Apply the Glow filter to the group.

This will give you the look you want, and you use the group's Fixed Res property to make sure the filter has enough space to work in.

Although this involves a bit of shameless advertising, FxFactory actually has a plug-in called Add Margin which is designed to get around this limitation in Motion.

Search for "Add Margin" in this page:
http://www.noiseindustries.com/fxfactory/motionpack

The immediate advantage is that it lets you work around the limitation in Motion so that your glows can "bleed" outside the original frame size.

The downside is that the FxPlug feature that allows third-party plug-ins to resize their output does not work in Compressor or when the Motion project is directly embedded in an FCP timeline. This is true for all third-party plug-ins, unfortunately. In other words, you will have to render out your timeline from Motion (for some, this is a serious limitation).

The other method (turning on the "Fixed Resolution" in the Layer/Group tab) works great, it will render correctly outside Motion, but it may require some extra parameter setup depending on which other plug-ins you're applying down the chain. If you've already keyframed point parameters, for instance, you may have to tweak your animation as a result of the image size being different.

Hope this helps,
Gabe
