Hi, this is Nick Horrocks, welcome to InCyberDigitalMedia, final cut pro tutorials.
In this tutorial I'm going to be looking at chroma gear filter, so what we're going to
be doing is putting our source footage, this shot on the left, onto a background and dropping
some text in, so we end up with three layers of video. So let's go to our sequence, the
first thing we do is drag our source foreground footage in, put it on video track 2. The first
thing we do once we've got that on the timeline is to add color smoothing, and that's down
here in the key section, color smoothing 411 and go up to filters, color smoothing 411
appears there. That's basically to help get rid of some of the jagged edges that we could
end up with. The color sampling you use depends on what your footage is, so there's 411, there's
420, there's 422 and 444, it just depends what your footage is. So you add color smoothing,
as you go along with the project you're going to drop other filters on here. Always make
sure color smoothing stays at the top of the stack, filters are applied in descending
order from the top, so just make sure that stays on the top all the time.
Okay so the next thing we do is to add our chroma key filter down here in the key section,
and it appears up here in the filters. Click on the visual button and you'll get this interface,
so basically you'll recognize this probably from color correction. You've got your color
spectrum up here on the top, your saturation, the amount of color, and your luma which is
the light and dark areas. This highlighted area here is the current selection range of
colors, and over here is the select color button which you click, and so what you want
to do is pick the green from a nice flat area, around here would be good. When you're shooting
it's really important to get nice flat lighting on your background, and it just makes life
easier when you come to keying it out, so do that, and you'll see that area is narrowed
down. If you hit shift and select your color pipette again, you select color and just keep
going round, keep picking these colors until you've got rid of as much as possible. Okay
that's fine, and we go back to our numeric interface which is here, so you've got essentially
the same controls numerically laid out. Edge control, this is just the first one to tweak.
Let's soften it a little bit. Hair is where you often get some problems, and it's an
area you've got to keep your eye on, anything like hair and fingers, and then horns. It might
be a good idea at this point to change your background so it becomes easier to see what
you're doing. So there you are, that's pretty good. Let's have a closer look. Not bad. This
area here, we can just simply get rid of by cropping. If we go to our motion tab, crop
left, and we'll just check that works because his arm may move into this area in which case
we'll have to do something else. That's fine, seems to be fine. Okay, so what we'll do is
we'll move him across there a bit, turn our background back on, and now what we can do
is put our background in. One of the encyber backgrounds, round all, and there you are.
Okay, so what we'll do is just spend a little bit more time tweaking that. Let's go back
to our chroma key interface. I want to get rid of that green in his glasses there. So
shift select color. Okay, that's good. Now we'll just go back to filters and take some
of this spread out. What we can do is have a quick look in the quick view just to see
what it'll look like. Still a little bit bumpy around the shoulder there. There's some green
going on over here as well, which we need to get rid of. Something to bear in mind,
if your clip has more detail around the edges, you could use the blue and green screen filter
in conjunction with the mat choker. You might get better results. So it's a very fine process.
There's a lot of tweaking and adjusting and seeing what works best. Back to chroma key
once more. Turn the frame off. See if we can just pick that up. Yeah. Back to filters.
See what we can do with the edge control. Okay, the last thing we'll do is just go and
put a drop shadow on him. Just pull him out of the background. 50 and 50. Okay. And then
we can drop some text into his left here. Pop that in there. Okay, now we'll render that.
Okay, so if you ever look at that, there you go. Well, I hope that was useful. It was very
brief, but those are the basics. It is really something you've got to spend some time on,
both in shooting and when you come to do the post production itself. But it's worth it.
If you've got any ideas for tutorials you'd like to suggest, then please do. You can get
hold of me on my channel on YouTube or you can email me at the website. Okay, thanks for watching.
I'll see you again.
