Data details The Data details section displays information about the asset currently open for annotation, or review. This information is gotten from the data itself, and is not available for direct manipulation. We use this section to provide you with valuable information about the data you are working on, including if we may have detected any possible issues with the data encoding.| Setting | Description |
|---|---|
| Data title | The title of the file currently open in the Label Editor. |
| Data type | The type of data unit currently open in the Label Editor. |
| Dimensions | The size of the image or frame currently open in the Label Editor. |
| Frames per second | frequently abbreviated FPS, this is the number of frames, or images, per second in a video. Higher FPS means smoother playback. This value is only valid for videos. |
| Browser compatibility | Some videos may have FPS or video encoding issues synchronizing drawn labels with frames in modern browsers. You can read more about supported videos here, and learn more about frame synchronization issues here and in our documentation here. |
General Settings
The General section of the Label editor settings contains the following components:
| Feature | Description |
|---|---|
| Auto-save interval | Controls how often labels are auto-saved (min: 15s, max: 600s, default: 120s). |
| Display bulk Approve/Reject buttons | Toggles buttons to approve or reject all instances in a frame. |
| Invert mouse wheel zoom direction | Reverses the default zoom behavior for scrolling up/down. |
| Display timestamps | Shows timestamps instead of frame numbers for object instances, attributes, and consensus review. |
| Turbo mode | Speeds up annotation by allowing rapid assignment/confirmation of attributes with auto-zooming. |
| Frame skip interval | Sets the number of frames skipped when using frame-skip buttons. |
| Enable ‘Jump to annotation’ buttons in video player | Adds controls to navigate directly between frames containing annotations. |
| Enable ‘Jump to classification’ buttons in video player | Adds controls to navigate directly between frames containing classifications. |
| Display data title | Toggles visibility of the data unit title in the Label Editor. |
| Expand classifications in classes list | Auto-expands all top-level classifications, making hotkeys visible for quicker annotation. |
| Expand all nested classifications | Auto-expands all nested classifications, making hotkeys visible for quicker annotation. This feature is off by default for better readability with deeply nested Ontologies. Enabling it might not work for very large Ontologies. |
Label Display Settings

|---|---|
| Display object names | Toggles visibility of annotation object names in the Label Editor. |
| Display object hash | Toggles visibility of the label hash (ID) for annotation objects. |

| Primitive keypoint sensitivity | Sets precision for selecting/moving keypoints (1.00 - 10.00). |
| Segment anything RDP parameter | Sets RDP parameter for (SAM). |

| Interpolation auto adjustments | Keeps manually labeled frames intact while adjusting interpolations with confidence scores below 99%. |
Object Tracking
Number of frames to predict Specify how many subsequent frames the object tracking should continue from the current frame. For example, if you start on frame 50, and set Number of frames to predict to 50, the tracker attempts to predict labels on frames up to and including frame 100. Advanced tracking This toggle enables the advanced SAM 2 tracking algorithm, which improves accuracy but runs at a slower speed. It is enabled by default.Keyboard shortcuts
The words ‘keyboard shortcuts’ and ‘hotkeys’ are used interchangeably and refer to the same concept.
