hey everyone it's grace from kapwing and i'm going to show you how to remove a certain color from a
video using chroma key technology that works online this works for removing green blue or
really any color from the video and can help you add special effects to your videos in addition
to making things like green screen memes reaction videos and other customized video content once the
video is transparent you'll be able to add a new background to the video whether that background
is a gif an image or another video we're going to be using an editor called kapwing to do this
in addition to being online it's completely free if your video is seven minutes or less and less
than 250 megabytes but processing videos in the cloud does get expensive for us so you'll need
to upgrade to caping pro if your video is bigger than that without further ado let's get into it
to edit green screen or chroma key videos online just go to the first link in the description below
and click that and you'll be taken to this tool kapwing so you don't even need to sign in to get
started all you have to do is click start editing we have a bunch of templates in the description
below where the green screen is already removed if you are looking for like a classic
template or meme check those out first we might already have one if you don't see a template that
you want us to make then just let us know in the comments below but uh to green screen any video
or chroma key any video you can either upload your file from like your local device or you can paste
a link i'm going to start with a green screen but this editor can do green screen blue screen
like any color so i found this video that i'm just going to copy the link to it and then go back to
kapwing and paste that right in so it pulls up the video and there's the green screen to remove the
background from the video just click the video and then click effects on the right side here
then click chroma key and the green automatically is selected this slider adjusts the threshold of
what is considered green and not so as you slide along you can see that more or less pixels will be
removed from the non-green part so if you move it to the left more of the pixel more of the
image is left in and you can see there's a little bit of green starting to p to creep in and then
if you move it all the way to the right it tries to remove every single bit of the green screen so
usually somewhere in the middle is a pretty good compromise and one thing to note is that the frame
rate is going to be decreased while you're editing when you export the video to download later
the video will look like the original just without the green screen so i'm gonna play a few seconds
here just so you can see what i'm talking about another one another one this one's pretty good
but sometimes the frame rate is is a little bit reduced when you're editing yeah so this was the
green channel and now that you've removed the green you can add whatever background you want
so whether that's an image a gif or a video you can add it behind this clip so for example you
can either upload these assets from your local files or you can just search in the images tab
for images or gifs and this sources from google images so if i just say like wall background
and then choose one you can send it backward i'm just going to zoom in so you can see this on the
right hand side there's a send backward button and that's how you can rearrange layers so just
click send backward and then it'll be behind the original video and you can see that
transparent with no green screen another one
so that was with a green screen video i'm going to show a blue screen video as well
so this is another video and i just copied the link went back here deleted that one
and then paste it so same process gonna go to effects click chroma and then click blue
and it immediately removes all the blue you can adjust the threshold again on the side here
but if it's a clear-cut video it should be pretty simple and the frame rate will also be a little
bit decreased as you can see then you can add your background this also works with any color so
that's the chroma key part is like you can just do key to color on the side here and select whatever
color you want to remove and it's not going to be 100 accurate but if the background is pretty
united in color it can work pretty well so i'm just gonna upload a video that i took of myself
as an example so you can see that the background is i tried to make it a single color this is
just a wall in my house and then if i click effects and then chroma key and then
key to color you can either choose a color from this palette here or type in a hex code you can
also use this color picker tool on the right here to select whatever color you want to remove so
if you move over the pixels on this image you can see that the right side the color is changing so
whatever color you choose it will remove that so i'm going to just choose this background wall
color and you can see it removed a lot more that's where you can use the other sliders down here to
adjust what exact brightness and saturation it chooses to remove so use these sliders
um you might have to like play around with them a little bit okay so i think i found a place where
most of the background is removed so as you can see the hue is like kind of towards the right
and the saturation and brightness are more towards the left and that really is just trial and error
like playing around with those sliders and seeing how the different colors change in your image so
now i can add my own background and this is what it looks like
so it's pretty good um i think it it especially when you have a background behind it the tiny
little errors aren't as noticeable and obviously the more solid the color is behind you and more
unified the easier that removing it will be another setting we have to remove backgrounds
even if you don't have a green screen or a certain color as long as a human object and face
is in it you can go to effects and then instead of chroma key you can just click remove background
this process isn't perfect either but it does a pretty good job of
getting the background of any color really and you can adjust the threshold to leave in
more of the photo or cut out some more but yeah this the remove background only works with like
human subjects and faces so if you're trying to chrom if you're trying to remove the background of
other non-human things chroma key is probably a bet a better bet so once you're done with your
video you can just click export video on this side here and then your it'll start processing
my videos on processing as you can see i've added a new background after removing the green the blue
screen and using chroma key you might notice a small watermark in the corner here that says
kapwing to remove that is completely free all you have to do is just sign into your account so
just clicking here and then signing in with either google or facebook account i just signed in and as
you can see there's no more watermark i'm just going to click download to save the video to my
device and then you can always go back and edit or make a copy of the project thanks for watching
