We’ve been working with DJ Yoda and here he is mixing and and so we need to key him out. He wants to appear in front of the visual output that he’s scratching. So how do we do that?
We have got a human segmentation thing. This will, using machine learning, find the person in the visual source and key them out.
So there we are, we can see it’s pretty good and you can see actually if you look down in the corner, there we are. That’s me, I’ve got, that’s a webcam running with human segmentation on it too.
But machine learning, look, it can’t be perfect in these things. And as you might have noticed Duncan actually has got a little green screen behind him. So let’s see if we can use that.
We’re going to add a behaviour.
Now we’ve got a chroma key. This the hue will find the colour and the tolerance is kind of the smoothing around that. Slide the the hue slider around till it just homes in on the colour you want to take out. There we are, we’ve got it perfectly do that with a tolerance down at zero.
Then you bring the tolerance up just until those crunchy green edges kind of go away, but don’t do it too far ‘cos otherwise things will start going semi transparent. So it’s just just about there.
But you can see that it’s a very nice key. Problem is of course, we can still see his room, but we know how to fix that because we can add an image key to that. So we can just mask that out there.
It was already set to this visual source here, which is just a manual mask I made in a black and white image in my kind of image editor program. So there we are.
That’s so now, here we can put Duncan into a 3D kind of stage set, into a 3D world around him. We could have audio reactive generator elements, we could have his big screen behind him. So that’s good.…continued in next post
