À propos de cet outil

Purpose-built for scalable video labeling, the tool enables frame-accurate bounding boxes, polygons, and tracks across sequences. It supports multiple annotation types, per-frame object IDs, and temporal interpolation to reduce manual effort. Data can be exported in COCO-like JSON, VOC-like XML, or custom schemas, facilitating seamless integration with ML pipelines and quality-control processes. The core value lies in reproducible labeling, team collaboration, and interoperability with standard datasets. Beneficiaries include AI researchers, data engineers, and media production teams needing reliable labeled video data for model training, evaluation, and asset tagging.
Conceptually, labeling progresses from loading video, defining label classes, annotating frames, linking annotations across frames, and exporting a corroborated dataset. The system preserves frame indices, spatial coordinates, and track continuity, enabling consistent metrics and audit trails. Unique differentiators are temporal interpolation between keyframes, robust import/export compatibility, and project-level governance for multi-user environments. Typical use cases include autonomous driving datasets, sports analytics, retail analytics, and post-production metadata tagging. The tool emphasizes data integrity, export fidelity, and scalable performance for long videos and large annotation crews.

Comment utiliser

  1. Upload a video and define label classes for your project.
  2. Create annotations on keyframes using bounding boxes or polygons and assign IDs.
  3. Use interpolation to generate in-between frames and review for accuracy.
  4. Validate spatial and temporal consistency with automated checks.
  5. Export annotations in COCO JSON or VOC XML formats for model training and QA.

Frequently Asked Questions

Trouvez des réponses rapides

What data formats are supported for export?
Exports are available in COCO-like JSON, VOC-like XML, and a flexibleJSON option. You can map labels, bbox coordinates, segmentation, and keypoints to standard schemas to integrate with your ML pipeline.
Is the tool free to use?
The platform offers a free tier for small projects with limited projects and storage, plus scalable paid plans for larger teams, higher project limits, and enterprise features.
Can I export and reuse annotations in other tools?
Yes. Annotations can be exported in widely adopted formats (COCO, VOC) and re-imported into compatible tools or pipelines, preserving class mappings and track IDs.
Does it support multi-user collaboration?
Yes. Projects support role-based access, activity history, and versioning to coordinate labeling efforts across teams while preserving data integrity.
