I tried to add a glow outline effect to my image to make the logo glow. It only glows when i push v. But it glows without the background.

Two methods:

Method 1:

Duplicate the clip and place one over the other (match frames if necessary).

For the top clip, apply the Shape Mask and shape it to fit the logo circle. Leave some "feathering" around the outline.

Set the top clip Compositing > Blend Mode to Vivid Light. You're done!

Method 2:

I originally used a glow filter from Motion (Light Rays) — most of the "glow" effects in Motion are already available in FCP, except, of course, Light Rays.

You can download the Light Rays Effect here:

[if you need help installing: https://fcpxtemplates.com/installing-plugins-for-fcpx/]

Use the following settings:

(Use the OnScreen Control to center the effect on the logo)

Use the Effects Masks > Shape Mask in place of the generic Shape Mask.

Using the Light Rays effect: there is no need to duplicate the clip (or mess with the Compositing settings) and no need to add the extra Shape Mask effect.

[These are not the only two ways to accomplish this...]

This variation is probably a little more extreme than you wanted?

There's really so many different things that can be done as long as you can isolate the various parts you want to "glow". (I'll come back to this.)

I used Light Rays for the circle logo, and Stroke for "Buc-ee's".

There's also something like this using a Glint filter (another Motion filter also not included with FCP :P):

Getting back to my point...

Using the Keyer is a royal PITA for this kind of thing. The irony here is that you can use the Light Rays effect AS a keyer!! ...but it's too difficult to explain how, so I won't.

Get this instead (it's free): https://fcpxtemplates.com/sckeyer-standalone/

If you don't have a Stroke filter, get that one too here:

(also free.)

Like the video, you will need to duplicate your clip and stack it. The un-edited version will be on the bottom.

For each part you need to isolate, you will need a separate clip.

Use scKeyer for a specific color or "area" (like the circular logo). Use the Effects Masks with scKeyer.

For example, you can use an Effects Mask > Shape Mask to select the circular logo, then check the Apply Mask checkbox. Then apply the Light Rays effect and adjust to taste [PS - it helps sometimes if you disable the visibility of the "layers" of clips below the one you're working on, then turn on the base clip to see the effect.]

For the "Buc-ee's", use Effects Mask > Color Mask and select the reds. [In this case, the beaver's cap will also be selected - you can opt to leave that in effect or add a Effects Mask > Shape Mask to "subtract" it from the color mask.]

After the scKeyer, you can add other effects (like Color Board) to make the color more saturated and brighter. Then add the glow/light rays [there are glow filters that do come with FCP...]

This is just 4 stacked clips:

the base, 1 for the circular logo, 1 for buc-ee's and one for the white text.

HTH
