Your Task

When you work on a video frame object tracking task, you need to select a category from the Label category menu on the right side of your worker portal to start annotating. After you've chosen a category, use the tools provided to annotate the objects that the category applies to. This annotation will be associated with a unique label ID that should only be used for that object. Use this same label ID to create additional annotations for the same object in all of the video frames that it appears in. Refer to Tool Guide to learn more about the tools provided.

After you've added a label, you may see a downward pointing arrow next to the label in the Labels menu. Select this arrow and then select one option for each label attribute you see to provide more information about that label.

You may see frame attributes under the Labels menu. These attributes will appear on each frame in your task. Use these attribute prompts to enter additional information about each frame.

After you've added a label, you can quickly add and edit a label category attribute value by using the downward pointing arrow next to the label in the Labels menu. If you select the pencil icon next to the label in the Labels menu, the Edit instance menu will appear. You can edit the label ID, label category, and label category attributes using this menu.

To edit an annotation, select the label of the annotation that you want to edit in the Labels menu or select the annotation in the frame. When you edit or delete an annotation, the action will only modify the annotation in a single frame.

If you are working on a task that includes a bounding box tool, use the predict next icon to predict the location of all bounding boxes that you have drawn in a frame in the next frame. If you select a single box and then select the predict next icon, only that box will be predicted in the next frame. If you have not added any boxes to the current frame, you will receive an error. You must add at least one box to the frame before using this feature.

After you've used the predict next icon, review the location of each box in the next frame and make adjustments to the box location and size if necessary.

The following graphic demonstrates how to use the predict next tool:

For all other tools, you can use the Copy to next and Copy to all tools to copy your annotations to the next or all frames respectively.
