Object Tracking
Persistent IDs for every object across frames, including occlusions, re-entries, and camera cuts.
Video Annotation Services
Turn raw footage into training data for tracking, action recognition, and event detection. Smart Annotahub labels objects consistently across frames, with stable IDs and precise temporal boundaries.
Types of Video Annotation We Offer
Frame-by-Frame Boxes and Polygons
Dense per-frame geometry when interpolation is not precise enough for your model.
Action and Activity Recognition
Start and end timestamps for actions, gestures, and behaviors, labeled to your taxonomy.
Event Detection
Rare-event tagging in long recordings, from safety incidents to key moments in sports.
Pose Tracking
Skeleton keypoints tracked over time for motion analysis, fitness, and robotics.
Video Classification
Clip-level labels and attributes for content moderation and retrieval.
How We Deliver Video Annotation
From your first sample to production volume, every project follows the same six-step path, with no commitment until the pilot proves the quality.
-
Step 01
NDA and Discovery
We sign an NDA first, then clarify your goals, taxonomy, edge cases, and target accuracy for the video footage.
-
Step 02
Free Pilot
We annotate a sample of your video footage at no cost, so you can judge quality, speed, and edge-case handling first-hand.
-
Step 03
Proposal and Agreement
Based on your pilot feedback, we finalize scope, timeline, pricing, and the Service Level Agreement.
-
Step 04
Team Setup and Training
We assemble a dedicated team, train it on your guidelines, and agree on communication channels and progress tracking.
-
Step 05
Production Labeling
Our team runs video annotation to the agreed plan, with throughput and accuracy KPIs tracked for every annotator.
-
Step 06
QA and Delivery
Your annotated video pass multi-stage quality review before delivery. Your feedback feeds straight back into the guidelines.
Video Annotation for Your Industry
Temporal consistency matters as much as per-frame precision. Our workflows check both.
Mobility and Autonomous Systems
Multi-object tracking for dashcam and surround-view footage.
Sports Technology
Player tracking, ball trajectories, and play-event tagging.
Security and Surveillance
Person and vehicle tracking with behavior and anomaly labels.
Retail Analytics
In-store foot traffic, dwell time, and shelf interaction.
Robotics
Manipulation and navigation footage for imitation learning.
Tools we work in
Your platform or ours. We adapt to existing pipelines, review stages, and export schemas.

Video Annotation FAQs
How do you keep object IDs consistent across long videos?
Annotators work on continuous segments with overlap, and reviewers run dedicated ID-consistency checks before delivery.
Do you use interpolation?
Yes, where it keeps accuracy within tolerance. Keyframe density is set during the pilot and adjusted for fast motion or occlusions.
Can you annotate only selected frames?
Yes. We can sample frames at a fixed rate or label only the segments that contain relevant events.
What video lengths can you handle?
From short clips to multi-hour recordings. Long footage is split into segments and reassembled with continuous IDs.
