  Keying with a border?

  Posted by Irene Driessen on September 3, 2013 at 5:57 am

  Hi, I’m trying to work out how to make a look like this: moving “cutouts” with a border, either the one from the keying bg or not. Is that at all possible without frame-based work?

  https://youtu.be/jxMPelMfAL8 Example of the look I’d want to achieve.

  I don’t know where to start my search :)…

  Thanks!

  This is fairly simple in a node-based compositor. The basic technique would involve creating a core matte and expanding it using a MinMax node.

  Conduit is a great, inexpensive node-based compositing plugin for FCP. The DV Garage website has a ton of useful tutorials that will get you up to speed on node-based compositing.

  The following video demonstrates creating a procedural garbage matte, but the technique used to expand the edges of the matte using a MinMax node is relevant to your question:

  Also see the push to white video:

  You could shoot your talent on a green screen, then use Conduit to create an effect like what your video example demonstrates.

  The newest new version of Conduit is PixelConduit, and there is a free version that has all of the functionality needed for most operations. I’m not sure that it works with FCP 7, however – the website says that it’s for FCP X and Motion 5.

  You could import the video into photoshop as stills, with alpha channel, and apply the Stroke effect in Layer Styles. Makes the edge color and width selectable. I *think* you can do this in Apple Motion, for sure you can in AfterEffects.

  So, I played around in Motion for a minute, and found how you do this. Your footage needs to be keyed first, but then just bring it into Motion and add Filter>Glows> Outer Glow. You get a 2-toned border to start, but this can be changed manually to create the white edge you want.
