Video Annotation

At LabelCo.Ai, we help your AI models understand movement in the real world. Whether it's a pedestrian crossing the road, a drone flying over farmland, or a player on a football field — we add intelligence to every frame with our expert video annotation services.

By breaking down videos frame by frame and labeling objects, actions, and movements, we help machine learning systems learn what’s happening over time — not just in a single picture. If you're building computer vision solutions, our accurate and scalable video annotations are the secret sauce to your success.

Why Video Annotation Matter?

Still images can tell a story — but videos bring it to life. That’s why AI models working on real-world applications need annotated video data that helps them:

  • Track movement and behavior over time

  • Understand object interactions and speed

  • React in real-time to changes in the environment

Whether you're developing autonomous vehicles, surveillance systems, sports analytics platforms, or robotic arms, high-quality video data annotation is essential.​

Bounding Box Annotation

What it is: We draw boxes around moving objects in every frame — from cars to people to animals.

Why it’s useful: It helps AI identify, locate, and track objects over time.

Use cases: Self-driving cars, traffic analysis, retail footfall monitoring, crowd safety.

Polygon & Polyline Annotation

What it is: We trace the outline of irregular shapes (polygon) or draw lines to mark lanes, wires, and edges (polyline).

Why it’s useful: Helps AI detect irregularly shaped objects and road/path boundaries with high accuracy.

Use cases: Road detection, farming equipment automation, electric power line inspections.

Object Tracking

What it is: We label and follow the same object across multiple video frames.

Why it’s useful: Enables AI to recognize and remember objects even as they move, change size, or get partially hidden.

Use cases: Surveillance, sports tracking, behavior analytics, drone monitoring.

Keypoint & Skeletal Annotation

What it is: We mark key body parts like eyes, hands, joints, etc., and connect them to map body posture.

Why it’s useful: Helps AI understand human poses, actions, gestures, and motion.

Use cases: Fitness tracking, gaming, animation, gesture control, healthcare diagnostics.

Semantic Segmentation

What it is: We label every pixel in a video frame with a specific class — like road, building, tree, sky, etc.

Why it’s useful: Offers deep context for scene understanding at the most granular level.

Use cases: Smart cities, autonomous navigation, agriculture monitoring, disaster response

3D Cuboid Annotation

What it is: We draw 3D boxes around objects to help AI understand depth and spatial positioning as they move.

Why it’s useful: Trains models to estimate distance, volume, and motion more accurately.

Use cases: Robotics, AR/VR, warehouse automation, automotive safety.

Lane & Road Annotation

What it is: We mark road lanes, shoulders, and curbs to train autonomous systems.

Why it’s useful: Essential for self-driving vehicles and traffic monitoring systems to stay within safe limits.

Use cases: Driver assistance, mapping, transport planning.

Frequently asked questions

Why is annotation important for computer vision?

Annotation provides the ground truth needed for training computer vision models. High-quality, accurately labeled images or videos help AI understand and interpret visual content like a human would.

How does video annotation differ from image annotation?

Image annotation deals with static frames, while video annotation involves continuous sequences, often requiring object tracking across multiple frames and time-based labeling for activities or changes.

How do you ensure the quality of annotations?

We use a Human-in-the-Loop (HITL) workflow with multiple quality control layers, expert annotators, review loops, and automation tools to ensure precision and consistency.

Can you handle large volumes of video/image data?

Yes, we are equipped to annotate millions of images or thousands of hours of video content, using scalable annotation pipelines, skilled workforce, and AI-assisted tools.

Is my data secure with your team?

Absolutely. We follow strict data security protocols including NDAs, access controls, encrypted storage, and GDPR-compliant practices to protect your data.
