Video annotator
Frame-level boxes with object tracking and action segments.
Timeline-scrubbed labels with keyframe interpolation, so annotators mark an object's position on a handful of frames and Studio fills in the rest.
Keyframe a handful of frames, not every frame
Set a box or polygon at the start and end of a motion, and Studio interpolates the frames between. Annotators correct drift instead of redrawing from scratch.
- → Keyframe interpolation for boxes, polygons, and keypoints
- → Persistent object IDs across frames for multi-object tracking
- → Timeline action segments with start/end scrubbing
- → Frame-accurate scrubbing at native or reduced frame rate

Built for video datasets
Multi-object tracking
Each object keeps a stable ID across the clip, so downstream training data links detections over time.
Action segments
Mark the start and end of an action on the timeline, independent of any single object's box.
Frame-accurate export
Export per-frame boxes and segments in the format your tracking or action-recognition pipeline expects.
