Multi-frame bounding box

You can use the Multi-frame bounding box tool to apply a bounding box to a series of frames and manipulate the size and the position of the bounding box across the frame sequence.

Labelbox uses interpolation to automatically adjust the size and position of the bounding box annotation across frames. To learn more about how we use frame interpolation, see the How it works section.


To learn how to create and modify a Bounding box annotation, see the How it works section.

To create multiple instances of a Bounding box class, simply select the Bounding box class from the Tools menu and draw the annotation. Repeat however many times is necessary.

When you copy and paste a Bounding box annotation from one frame to another, its position and size are preserved. By default, the copied annotation will persist until the last frame of the video.

The easiest way to delete a Bounding box is to select the annotation and press the backspace key.
