Best AI Video Annotation Tools (2023)

The process of adding metadata, tags, or labels to various objects, actions, or events in a video is known as video annotation. Human annotators can perform this manually, but with AI, a significant portion of the process may be automated. AI algorithms use computer vision to examine and comprehend the contents of the video frame by frame and then recognize and classify objects, actions, or events based on their visual elements.

Let’s look at some of the best AI video annotation tools.
