An overlay is any additional visual element that is placed on top of the main video footage. This can include graphics, titles, logos, watermarks, or any other visual element that is used to enhance or supplement the main video. Overlays are often used to add text, branding, or other information to a video, or to create visual effects such as transitions or filters. They can be created using a variety of software tools, such as Adobe After Effects, Photoshop, or Premiere Pro.
