# Batch mode (for dynamic objects)

{% hint style="info" %}
Batch mode is only available for 3D cuboid labeling.

Tip: [use your GPU in Chrome](https://segmentsai.notion.site/How-to-use-your-GPU-in-Chrome-2b95e19fb77c456c87f798013769a98a) to make sure the 3D point cloud interface runs smoothly.
{% endhint %}

When labeling or reviewing dynamic objects in 3D point cloud sequences, working object by object is usually the most efficient way to obtain precise annotations. However, this means navigating through the different frames in a sequence constantly. To make this process more efficient, we developed batch mode. Batch mode shows you an object in multiple frames at the same time. This way, you can easily choose where to make adjustments to label an object, and easily review an object by simply scrolling through the frames.

This video shows how you can use batch mode to quickly adjust a cuboid.
{% endembed %}

## Toggle the batch mode

1. Select the object you want to adjust/review.
2. Click on the batch mode icon (![](/files/OfQkX5jzy7QU40T9BBWa)) in the right toolbar to toggle batch mode on/off.

You can also exit batch mode by pressing the hotkey (`Escape` by default).

## Select a frame

Clicking somewhere in a frame to select the frame. If you want to select the previous or next frame, press the back or forward arrow, respectively.

## Zoom in/out

* Double-click a view to zoom in on that view.
* Press the hotkey (`Shift` by default) + double-click a view to zoom out on that view.

## Edit the object

Object editing works exactly in the same way as in the single frame interface, so you can still use your mouse or the hotkeys. See the following pages:

[3D point cloud cuboid interface](/how-to-annotate/label-3d-point-clouds/3d-point-cloud-cuboid-interface.md)
{% endcontent-ref %}

## Remove the object

1. Select the frame where you want to remove the object.
2. Press the trash icon on the left of the frame.

## Add the object to an empty frame

1. Select the empty frame where you want to add the object.
2. Press the plus icon on the left of the frame.

## Use keyframes

Keyframes work in the same way as in the single frame interface, see [Use keyframe interpolation](/how-to-annotate/label-sequences-of-data/use-keyframe-interpolation.md). The only difference is that keyframes are now displayed directly next to the frame.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.segments.ai/how-to-annotate/label-3d-point-clouds/batch-mode-for-dynamic-objects.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
