You can use the Video classification tool to add Classifications to select frames in a video.
The following is not supported:
- Text or dropdown classifications in export
- Undo/redo actions
- Create classifications via the API
- Exports for mixed media (e.g. videos & images in the same project)
Import your video data
First, create your project in Labelbox and ensure your videos are in .mp4 format. To learn how to import your video files directly, see Direct upload. To learn how to import your video URLs via JSON, see Import via JSON. To learn how to attach metadata to your imported videos, see Asset metadata via JSON.
To learn how to import programmatically, see Bulk add data rows.
Set up video classification
- Create a project.
- Select “Editor” as your label editor.
- Click “Add classification”.
- Select “Radio” or “Checklist” as your classification type.
- Click “Confirm”.
- Click “Complete setup”.
How it works
The Labelbox labeling interface will have some additional tools for labeling video data.
Drag the endpoints on the zoom bar to adjust the amount of frames selected in the timeline. You can also drag the selection across the zoom bar to move to a different part in the timeline.
The timeline shows the temporal progression of the video clip. You can hover over a frame in the timeline to preview it.
A single frame can have 0 or more classifications. You can assign a classification by selecting one or more frames in the timeline and choosing a classification from the left sidebar.
Below are some helpful shortcuts for selecting frames.
Select a set of consecutive frames on the timeline by clicking the first and last frame in the set.
Select individual frames on the timeline.
Seek the previous/next frame.
Add the previous/next frame to the selection.
