Video Annotation

The only frame perfect labeling experience

Most online video annotation tools use heavy compression and streaming techniques that cause inaccurate frame estimations. In some cases, annotations can be wrong up to half a second. That’s why V7 uses a proprietary video streaming system to serve you frame-perfect visuals, at the file’s original resolution, fast, anywhere in the world.

What are the steps involved in model training?

If you decide to train your computer vision models on our platform, all you need to do is complete at least 100 annotations of a specific class. Then, you can pick the datasets and classes to train object detection, classification, or instance segmentation models with no additional steps.

What pricing plans does V7 offer?

V7 offers three pricing plans: Team, Business, and Pro. The team plan starts at USD 5,000/year. For detailed pricing and feature overview, see the V7 pricing page.

Can you handle large volumes of data for annotation?

Yes, V7 is equipped to handle large volumes of data for annotation. It offers efficient and scalable data management capabilities, making it a great solution for organizations with large datasets.

What kind of annotations can be performed using V7?

V7 can perform various types of annotations for tasks, including object detection, semantic segmentation, and image classification. There are multiple annotation classes, such as polygon masks, bounding boxes, keypoint skeletons for human pose estimation, etc.

What is V7?

V7 is a data training platform that focuses on automation and ease of use. It offers advanced machine learning capabilities, and V7’s key feature, Auto-Annotate, utilizes AI to quickly segment objects in an image, reducing the time required to make annotations by up to 10x.

What is the pricing for data annotation and custom model training services?

V7 uses a system of credits that are consumed when you use specific tools or perform operations such as model training. When it comes to data labeling services, the cost depends on several factors, such as the size of the dataset, the complexity of the annotation tasks, and your deadline. Therefore, it's best to reach out to V7’s team to discuss your requirements and get a quote.
