this video I'm going to show you how to use a free online artificial intelligence
rotoscoping tool for your projects in HitFilm. Before we begin, if you like to learn
little tips and tricks like this that will make your vfx creations easier and less
time-consuming, then please consider subscribing to my channel and click the little bell icon

the past week or so, and you haven't seen this yet, boy are you going to be impressed! So
I'm working currently on this project file of a superhero landing, and the thing about it is
that when the superhero lands (that would be me) there's going to be assets that I lay in here...
ground cracking and debris and dust. Some of that goes behind and some of that comes in front.
As a result, it's necessary to rotoscope out the person (the superhero... that would be me) who
is landing here to make sure that there's proper occlusion of those assets as they're there. So the
deal is, I'm going to use this AI rotoscoping tool that is free and online to do that so. The
website is runwayml.com, and what you do is you just click on sign up to create your own
personal free account. After you have done that, then you will be presented with this page, and
on the very top you have the beta green screen. You just simply click start editing and it gives
you a bunch of practice videos, or you can bring in your own video, which is what I'm going to
do. So I'm just going to grab my landing mat and drag it right in here. Now depending on
how big the video is will depend on how long it will take for that to load up. My video is very
short, so it didn't take hardly any time at all. Now that I have it in the media bin, I'm just
going to go ahead and drag it here into the editor. You can see that it is now placed
here. I can use my mouse wheel to zoom in, also using the Z key, and you can use the H key to
pan. What you want to do is start adding keyframes here to either include an object or to exclude an
object. So I'm just going to move in a little bit, and I'm just going to click here on my pants.
So now it's going to start generating a mask... so that looks pretty good! You can start scrubbing
through and ask it to show you what the mask looks like on any different frame in your video. So in
this case, let me back up and let me just hit the preview button, and it will actually generate an
entire preview of that. To be honest, that looks really fantastic. It's hard to to say that I
need to really do much of anything else. So I might just go with that. Understand though that
if I wanted to, I could exclude certain things, and this and that, when I feel that I have
something that I like. Then I can go ahead and hit the export button. What that does is it
provides me with this green screen version which I can also see. Still looking very very
good! Clicking the export button again, you can see that if I wanted to
only export the alpha channel, clicking on this, requires a pro membership. If
I click on the pro membership, then you can see how much it is if you bill annually, there you go,
kind of a thing. All right, but even without that, if I wanted to go HD, then I could
go HD instead. Again, I would have to have a pro membership. I'm just going to go ahead
and go with the free version... the 640x360 green screen version. I'm going to click export video,
and again, depending on how big your video is, it may take quite a bit of time for this
to process. Since my video is really short, it won't actually take that long. Then when it's
done, it will give you the option to download it. It sends you an email to let you know when it's
done and ready to be downloaded, which is kind of nice actually! Then you just highlight this,
click on the three dots, and click download. After I've downloaded those, I will just go ahead
and drag them into HitFilm. Notice that I have the original, and then I also have the green screen.
So if I were to make the original into a composite shot, and then I were to bring the green screen
in, you will see that the green screen is actually not the same size. So what I would do is right
click on this, and Transform Fit to Frame. So now it is exactly the same size. If I went to search
up for Green Screen Effect, then I could drop that right onto here. You can see that the quality of
that video is considerably lower because it's a smaller resolution, but that's okay, because
what I'm going to do is put that underneath. Then I'm going to add a grade
layer which will be in between, and I will go ahead and call that grade layer
the "Matte." I can actually turn those two off. The Landing Matte. I'm going to go ahead and
duplicate it, and the second one I'm going to add a Set Matte Effect to. Then I will source the
Matte grade layer. So now you can see that that is its own rotoscoped item there. After making
a few tweaks, then I can go ahead and use that as my matte to build the other assets in. So is
it perfect? No... especially the free version, but I'll tell you what, it sure gets you a lot
of the way there when it comes to rotoscoping. It wouldn't take much to be able to clean that
up and really make it workable for your project. I'm Jay Haynes for the Film Sensei
