Here’s the results after this foreground adjustment. Notice that I’ve been careful to make sure not to draw over the green background.
In this case, I’m drawing a line through her hair that tells the software that the colors under this line are part of the foreground. This tool allows you to draw a thin line to select areas of the image. The rectangle is the default, and allows you to select areas of the image using a rectangular marquee, but I like the control of the Pixel line better. There are two selection tools – RECT and PIXEL. To clean this up, click the FG Opacity button. The big problem is spill through her hair. This is how the key looks immediately after clicking Auto Setup. More times than not, this will get you close to a finished key.Ĭlose, but not close enough. The easiest way to start is to click the Auto Setup button. To see the entire interface, grab the vertical bar in the column header to the right of Parameters and drag it to the right until you see the entire interface. You apply this to a clip the same as any other filter, then double-click the Timeline clip to load it into the Viewer, and click the Filters tab. This is the interface to Primatte Keyer Pro 4 (hereafter called PKP4). The folks over at Red Giant Software sent me a copy to use for both my recent chroma-key webinar and this write-up. But the one I want to talk about today is Red Giant Software’s Primatte Keyer Pro 4 – the big brother to Primatte RT. There are lots of different keyers on the market. Look at all the green fringing, the lack of detail, and the giant, glowing arrow that says “Bad Keying Done Here.” (I, uh, made that last part up, but you know what I meant…) It isn’t bad, if you exclude the hair, However, with the hair, its awful. To illustrate here’s a professionally shot and lit green screen that I purchased from iStockPhoto for my recent webinar on chroma-keying.Īfter applying and adjusting the Primatte RT keyer, which ships with Final Cut Pro, I got this key. The Primatte RT keyer is nice keyer, but it has problems with both hair and transparency. Since then, Apple moved this keyer into Final Cut Pro 7 where it replaced the egregiously bad keyer that Final Cut had been using since its release. At that time, I showed you how to use the Primatte RT keyer in Motion.
