Green screen is a popular effect on TikTok.
It allows you to put any background behind you.
To use it, open the app
and click the plus sign
at the bottom of the screen.
Tap "Effects" to the left of the red record button.
Tap "Green Screen."
Upload your background image
by pressing the plus sign
and select your photo or video.
You can also pick from TikTok's library.
You'll be superimposed
onto the video or photo you've selected.
You can adjust yourself in the video
by expanding, shrinking, or moving your image.
If you're recording yourself,
you can use the timer feature
to select the length of your clip
and give yourself three or 10 seconds to get ready.
If someone is recording you,
they can just hold down the red button to record.
When you finish with one section,
you can pick another background
or repeat the process until you're done with your video.
Now you're ready to post.
