How do I do a Track Matte transition or Alpha Transition?

[Jeff Kirkland]

You can set up your own using Motion or you might look at the plugin available from this web site.

Isn’t there a way to do it by setting track mattes or luma mattes to a layer within FCPX?

You’re looking for “stencil luma” or “silhouette luma”.

[Ian Dillon]

But then you have to add another layer and designate it as “behind” which gets confusing. Someone should make a tutorial, but no one cares about FCPX.

That’s certainly one way to do it, but you don’t necessarily have to.

What exactly is your media and what are you trying to do?

Matte, fill, and background?

[Ian Dillon]

I was able to get it to work by adding another layer and designating it as “background”, as the other post mentioned, but I still don’t know what the heck “background” means or does, so knowing how to do it and not knowing why is really annoying.

Also, I was unable to get that after market alpha matte plug-in to work properly.

Can you please tell me an easier way?
I have one matte layer animation (black and white), and one clip animation with an alpha channel transparency background. The clip with alpha should just sit on a top layer by itself, but incorporating that matte into the lower layer is the hard part. No Track Matte feature like After Effects. There’s got to be an easier way.

Thanks in advance,
Ian.

So let me get this right.

You have a layer with an alpha, a matte, and a BG?

What are you using as a matte fill?

There’s also stencil alpha? Sorry, trying to get a clear picture of your layers.

Thanks for troubleshooting this with me.

I would like to have my team members be able to use this custom one second transition without going into Apple Motion.

The transition consists of two clips I created in After Effects:
Clip 1 – A one second clip of a magnifying glass stock image coming onto the screen from the right, then we zoom fly through it. It has an alpha channel transparent background.
Clip 2 – White background, then a black circle that represents the magnifying glass interior comes on screen from right, then we zoom fly through it. Whole screen then becomes black.

Of course I also have my outgoing and incoming footage in the timeline that I would like to transition between using the magnifying glass transition I just mentioned.

Thanks in advance,
Ian.

Sorry for the delay.

I think I know what you’re saying.

Outgoing clip is playing, There’s a magnifying glass comes in from right (alpha movie) it stops in the middle and we fly through the middle of it. In the middle of the mag glass is the incoming clip?

If so, then you setup the outgoing clip with the black and white matte up first. Put the matte above the outgoing clip and set Blend mode on the matte to “stencil luma”. You then have to compound those clips.

Set the alpha movie on top, and put the incoming clip on the bottom (the compound clip is now in the middle).

Forgive this crude model, but it should look like this?

OK. Thanks for the demo. So let me get this straight. The key difference here is that I have to compound those clips. How do I do that?

Thanks,
Ian.
