What is video annotation?

Video annotation refers to the process of adding metadata to a video file, typically in the form of labels or descriptions. This metadata describes the content of the video, including the objects, people, and actions that are depicted in the footage. There are several different ways to annotate videos, depending on your goals and the resources available. Manual annotation. Human viewers watch the videos and add labels. Automated annotation. A computer algorithm labels objects and actions in the videos. Combination (human in the loop). An automated system generates labels and human viewers verify edge cases where the label confidence is low, or do spot checks.

What are the challenges of video annotation?

The biggest challenge in video annotation is the time and resources involved. Video annotation can be a time-consuming process due to the sheer volume of data. A fast and affordable way to overcome this challenge is to break the task down into bite-size pieces and distribute it to a large crowd of annotators. Toloka's global crowd is available 24/7 to handle data in over 40 languages.
