We have seen now how to draw and propagate objects in our label editor. Let’s take a look at frame-level classifications.
You can instantiate a new classification from the left handle panel in ‘Classes’ (or use the appropriate hotkey). Initiate the classification value from the panel whether ‘Text’, ‘Radio’, ’Checklist’ or a nested classification.
Initiating a classification will create a frame range above the navigation bar that you can use to set the frames for which this classification applies.
You can enter the frame numbers directly within the range bracket on the lower left of the range bar, drag the ranges in the range bar, or set the range values to the current frame through ‘Set end to current’ and ‘Set start to current’ buttons.
Adding and removing ranges
If the classification has multiple disconnected frame ranges, use the ‘Add range’ and ‘Remove range’ buttons to manipulate the set of ranges to get to values that apply.
Once the classification is set, you can view the values in the left panel under ‘Instances’. An overview of the frames that classification appears in will be displayed in the bar. Hover over it to find the exact frame ranges.
Editing and navigation
You can always change the range of frames of a particular classification by clicking on the vertical ellipsis on that classification in the left hand panel and clicking on 'Edit range'.
This menu will also help you navigate to the next frame with this particular classification by clicking on 'Go to classification'.
