Technically known by the name of chroma , or color key , it consists of an audiovisual technique implemented not only in film or photography, but also in television, based on the extraction of a color from an image or video and replacing the area originally occupied by another video or image with the help of a computer or specialized equipment.
This is an excellent option when, for example, it is not possible to travel to the area where we originally want to make the recording, it is too expensive, or when we simply need to avoid cropping the protagonist frame by frame (which is known as rotoscopy).
Of course, for chroma to work as it should, it is essential that the person’s clothes or what is in front of the background are not the same color , since, if they are not, the effect will be transferred to the rest. Of content.
In most cases, the most common is to use a green background . Precisely, if you use an app or video transmission platform, it is possible that at some other time you have used this technique. However, did you know that it is also possible to do it on TikTok ?

The use of a green screen or chroma within TikTok can be an excellent way to improve our video clips, being able to move us to a new location or even add a much more elegant effect to our creations.
To do this, we must click on the ‘+’ button, which in this app is essential for creating new content. Then, click on the Effects button and then on Green screen effects .
If you have doubts about which button to use, you should know that in this area you will find two slightly similar buttons. The one that interests us this time is the green screen button , which looks like or reminds of a photograph with an arrow pointing down.
Now, we touch the photo that we want to include as a background in the list of photographs, and if it does not appear, we can click on the ‘+’ button to search for more snapshots.
Now we place our video where we want by following the different controls that will appear on the screen, and we begin to record our video. When we are done we will have to click on the check mark .
Finally, we adjust any other settings, touch Next , fill in the rest of the screen as usual with the information related to the publication, and click on Publish .
