DATASET MANAGEMENT FOR AI VIDEO ANALYTICS

Upload Any Video Format and Label Entire Clips in Minutes

Organize your video annotation projects in the cloud to get better control and visibility. Use advanced dataset filtering, video tagging tools, AI-assisted video segmentation, or object detection with bounding boxes.

Interpolate any video annotation

Use keyframes to annotate your video data faster. Instead of adjusting your labels every single frame you can morph between longer sections of your video clips.

Add thousands of annotations

You can add up to 700K+ annotations and render them simultaneously, even with complex shapes such as polygon masks for video segmentation.

Edit labels right from your browser or add them in bulk via the API. Leverage ML models for video object detection to create annotations at scale.

Use multiple slots for labeling videos in sync

Create custom layouts and grids to label footage from multiple cameras. Set up custom multi-slot views to compare differing video frames of the same footage.

We conducted an extensive research of annotation tools and ultimately chose V7.

It fits our business needs best due to its customizable workflows, simple setup, consensus stages, and the ability to monitor annotator performance and project progress. It's also very intuitive and stable.

Frequently asked questions
Reach out to our support team or contact us for further questions
How does Consensus stage work with video annotations?

The Consensus stage assesses the degree of agreement among multiple video annotators by analyzing the overlap between independent annotations. In most cases, however, annotators may add or remove video annotations at different points, making frame-level agreement challenging. For instance, determining the exact frame where an object enters the scene can be subjective. Still, the Consensus stage is crucial for evaluating the degree of overlap for specific keyframes in subsequent QA reviews. Make sure to add a Review Stage immediately after using Consensus on videos.

What does FPS parameter mean in the V7 video data import panel?

The FPS value corresponds to the number of frames per second. However, by "frames," we are referring to the frames available for annotation, not all frames in general. This means that V7 does not reduce the frame rate of the video itself. All videos are imported and can be previewed at their native frame rate, but not all annotations are editable at every frame if the video has been imported at a reduced FPS value.

What is the best video annotation tool for developing commercial AI products?

V7’s ability to handle various video formats, provide real-time collaboration, and ensure regulatory compliance make it a highly reliable and comprehensive tool for commercial AI development. To compare different functionalities, you can read this guide to best video and image annotation software.

How does V7 handle different video formats?

V7 supports all popular video formats including .mp4, .mov, .mkv, and .avi, allowing users to upload videos in their native frame rate without losing quality. Video preprocessing involves mapping imported videos onto the annotation timeline in V7’s annotation panel, but the previews are based on your original file.

What is video annotation in the context of machine learning?

Video annotation is the process of tagging or labeling video frames with information that can be used to train machine learning models. This can include generating bounding boxes, segmentation masks, keypoint skeletons, polylines, and other types of labels on videos. You can find more information in our guide to video annotation.

Are there any limitations connected to video length or quality?

V7 supports both long videos and utilizes proprietary back-end performance boosters for rendering densely annotated videos. At some point, there may be some limitations related to your browser's memory. However, these can be avoided by following best practices, such as designing an optimized annotation class structure.

What programming languages and frameworks are compatible with the V7 platform?

You can use V7’s Darwin-py SKD to interact with the platform via CLI or use it as a Python library. The full documentation and API reference is available in the V7 resource hub.

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.

How do you handle version control for models and annotated data?

V7 provides version control capabilities that enable you to manage and track changes to your models and annotated data over time. You can also use the export/import feature to revert to previous versions of your annotations if needed.

Can I test V7 before making a purchase?

Yes, V7 offers a free trial version that allows you to test its features and capabilities before making a purchase. However, to unlock all the functionalities and all the potential that the platform offers, it is worth considering one of the paid plans. You can see the full feature breakdown and pricing of V7 here.

Can you integrate the trained model into our existing system?

The V7 platform allows you to bring your own custom models, hosted on your own infrastructure. You can use them alongside the models trained using V7's own neural networks. The minimal requirements for the custom models are that they must be exposed via HTTP and make predictions in the form of JSON.

Can multiple people label the same asset in V7?

Yes, multiple people can label the same asset in V7, making it a powerful collaboration platform for your data labeling projects. V7 also includes comment tools, user permissions, or consensus stages that measure the level of agreement between different annotators, allowing you to quickly identify any discrepancies in annotations. These features help to improve the quality of your data labeling process and ensure that your annotations are accurate and consistent. With V7, you can manage large-scale data labeling projects with many collaborators.

How do I know if V7 is right for my use case?

V7 was built for multi-industry use cases and you can get in touch with us to discuss your project in more detail. Also, take a look at V7 industry pages to learn more about the benefits and to see various implementations.
