Video Annotation

Frame-Accurate Video Annotation for Dynamic AI Systems

Video AI systems require temporal consistency that image annotation alone cannot provide. Centric Labs delivers frame-by-frame and interpolated video annotation for object tracking, activity recognition, and scene understanding — with the precision that autonomous vehicles, surveillance systems, and robotics applications demand. Our teams annotate thousands of hours of video monthly, maintaining object identity across frames and handling occlusion, re-identification, and complex multi-object scenarios.

Comprehensive Video Annotation for Every Use Case

We deliver object tracking with persistent identity across frames, activity and event recognition labeling, temporal segmentation and scene boundary detection, interpolated annotation for efficient high-frame-rate processing, multi-camera and multi-angle synchronization, and specialized protocols for autonomous driving including lane tracking, pedestrian intent, and traffic sign sequences.

AI-Augmented Annotation for Video at Scale

Video annotation is inherently more complex and time-consuming than static image labeling. Our platform uses AI-assisted tracking to propagate annotations across frames, reducing manual effort by up to 70 percent while maintaining human oversight at critical frames. Annotators focus on correction and validation rather than redundant labeling, dramatically improving throughput without sacrificing accuracy.
