Video classification

For this type of project, you can use the Hand gesture classification preset.

This preset helps you classify video content by specified categories. You can use it for content rating and moderation, detecting noise and other imperfections in the video, or training computer vision.

Take a look at the example: the labeling interface includes a video player, and several buttons for categories. Note that validation, keyboard shortcuts, and task layout are already configured in this Template Builder sample code.

Components used in the example

You can add media files (audio files, videos, images) from your own server, a cloud storage like Google Cloud, Amazon AWS, or Yandex Cloud.

If this preset doesn't meet your needs, see other examples in this section.

Check that the video is fully viewed

If you want to be sure that a Toloker watched the whole video, replace the condition.played component with condition.played-fully.

Add a layout

To enhance Toloker's experience, you can highlight different types of data with colors using view.alert. You can place it in the view.list along with the other components.

In this example, the description is highlighted with a blue border, and the buttons are highlighted with a yellow one.

Other options for buttons

Decide whether a Toloker can select only one or multiple answer options.

Multiple options (checkboxes)
One option (a radio button)

If there are several possible answers to the question, use the field.checkbox-group component.

Add clarifying questions to one of the options

The helper.if component displays an interface element after a specific response is selected. In this example, a Toloker can only select correct statements about the video if it is loaded.

If you need to check sequentially more than two conditions, use the helper.switch component.

Does the video match the search query

Add a button that opens the search results and generate a search query link using the component. To make sure that a Toloker clicked on the link and checked its contents, configure validation, as in the example.
