# Sample mode

If you use the annotator without a GPU or you have less than 20 labels confirmed, the annotator will be in sample mode. What this means is the thumbnails will be picked from your first video at regular intervals, this is called uniform sampling. For example if your 1st video was 7 minutes long each thumbnail would be 1 minute apart. \

In sample mode if you wish to navigate to another file you can use the Lodestar Link method which is described in the shortcuts guide.

## 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.lodestar.ai/dataset-management/video-annotator/modes-while-annotating/sample-mode.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.
