What is Video Recording and Labelling?
Capturing or collecting video data through cameras or other sources, and annotating or labelling objects, events, or scenes within the video frames to train AI models.
It’s essential for enabling machines to understand, track, and predict movement, behaviour, or patterns in dynamic visual data.
This process is a cornerstone for AI systems in autonomous driving, surveillance, sports analytics, robotics, smart cities, and healthcare.

1. Video Recording: Capturing the Data
Sources of Video Data:
- CCTV/Security Cameras
- Dashcams or Autonomous Vehicle Cameras
- Drones or Aerial Footage
- Surveillance Systems
- Medical Scopes (e.g., endoscopy)
- Sports Matches or Training Sessions
- Mobile Phones or Wearables
- Industrial Cameras in Manufacturing
Key Considerations in Video Recording:
- Resolution & Frame Rate: Higher quality gives more accurate annotations.
- Lighting & Clarity: Affects object visibility and model accuracy.
- Viewpoint/Camera Angle: Fixed, rotating, or moving camera.
- Environmental Conditions: Day/night, indoor/outdoor, weather variability.
Data Privacy Note:
Always ensure video data complies with GDPR, HIPAA, or local data protection laws when it involves people or sensitive environments.


2. Video Labelling: Annotating for AI
Video labelling is the process of marking specific objects, movements, or events in each frame or over time.
Common Video Labelling Tasks:
Object Detection: Drawing bounding boxes around objects (people, vehicles, animals)
Object Tracking: Tracking movement across multiple frames (pedestrian tracking, ball tracking)
Action Recognition: Labelling specific activities (jumping, falling, hand-raising)
Pose Estimation: Detecting keypoints/joints on the body (sports training, medical posture analysis)
Lane/Path Annotation: Labelling roads, drivable areas (autonomous driving)
Event Detection: Marking complex events or incidents (accidents, violations, gestures)
Scene Classification: Tagging scene types (urban, rural, indoor, outdoor)
Audio-Video Sync: Syncing speech or sounds with actions (video captioning, surveillance)
