Classes

Classes are a way to identify your items and instances, and categorize them further by using Attributes.

You can create an Object class, which is used for object instances, and you can create a Tag class, which is used to classify items as a whole. Learn more.

Assign classes or attributes

When in the Video Editor, you can assign a class to the item you’re looking at. You may also assign attributes, if the class has any.

You can assign a class in a number of ways.

Method 1

1. In the Video Editor, create an instance with any annotation tool (except the Free text tag).
2. Right-click the instance to open up a menu or find the instance in the Right panel.
3. Select a class from the dropdown.
4. Select attributes, if applicable.

Method 2
Select a class from the Default class feature in the left panel before you annotate. Your annotation tools will now automatically assign the selected class to any new instances you create.

Method 3

1. In the Video Editor, select the Eyedropper tool. (If you can’t see it, press I on the keyboard or right-click on the Free text tag tool to find it).
2. Click on the instance that has a class you want to replicate. The Eyedropper tool will change to the Bucket tool.
3. With the Bucket, click on the instances you want to assign the selected class to.

📘

• After you’ve used the Bucket tool, if you switch to other tools then back to the Bucket, it will keep using the last class you selected with the Eyedropper.
• You can manually switch to the Bucket tool from the left panel, or by pressing B on the keyboard.

Change a class or attribute

You can change a class or attribute by right-clicking the instance or finding it in the right panel. From the class/attribute dropdown, select a different option.

Remove a class or attribute

To remove a class or attribute:

1. Right-click the instance you want to change, or find it in the right panel.
2. Click the X corresponding to the class name or attribute to remove it.
