Video classification

You can use the Video classification tool to add Classification annotations to video frames. Only radio and checklist classifications are supported when labeling videos.

A single frame can have 0 or more classifications.

By default, when you assign a Classification to a single frame, the annotation will persist until the last frame of the video.

However, if you would rather limit the Classification to a set of frames, you must select a set of frames before applying the Classification.

When you select a set of frames on the timeline, the left sidebar will only show the active classification state when the classification is true for all frames selected.

The easiest way to remove a Classification annotation from one or more frames is to select the frame(s) and click on the x next to the answer in the left panel. This will toggle off that classification on all subsequent frames.
