A digital effect, popularized by the TikTok platform, enables users to replace the background of a video with a chosen image or video. For example, a creator could film themselves in front of a plain wall and, using this effect, superimpose a scene from a popular movie behind them, making it appear as though they are actually within that environment.
This background replacement capability is significant because it empowers content creators to enhance their visual storytelling without needing access to physical locations or elaborate sets. It provides an accessible method for adding context, humor, or visual interest to videos, which can lead to increased audience engagement and wider reach. Historically, achieving such effects required dedicated studio space and specialized equipment.
