don’t understand alpha and luma mattes
I’m using a matte that has black in the center and white on the outer edge. It is sort of a scribble pattern. I am confused on how to use this opinion. I want to cut out a piece of video that has jagged borders using this matte and have the layers beneath show up. I have my video clip on top of the dv matte and the video clip itself is set to traveling luma matte and the actual matte itself is normal composite mode. The black turns into alpha channel. I want the inverse of this. Wouldn’t that be traveling alpha matte?
I am confused and I don’t know if any of this makes sense.
Also, how do i create my own mattes, especially for words, ect., beginner question -

Jeff,
Have a look at some tutorials by Walter Biscardi, one of this forum’s leaders. The link below will take you to the 1st of 3.

It’s easy to reverse a matte. Just add a Channel > Invert filter to the matte, set the dropdown menu in the filter to RGB and all will be well.
Travel Matte Alpha and Travel Matte Luma effects are built the same way.
V3 Graphic Fill (what you want to play in the matte)
V2 Matte itself
V1 BackgroundSelect the V3 clip and apply the Composite Mode > Travel Matte Luma
Any standard clip will work for a matte, but it’s helpful if it’s black and white.
If the matte contains an alpha channel (which you can embed in Photoshop, After Effects and with certain FCP operations), you can and should use the Travel Matte Alpha mode instead. Why? It generates a cleaner matte with smoother edges.
Walter’s movies will also help you.

Just click on my head at the top of this forum and scroll down to my three part series of Travel Mattes. They’re free and I think you’ll have a great understanding of both how to create them and how to use them.
