Video Annotation Services & Solutions

Building an efficient and smart system that thinks and acts like a human, demands a vast amount of training data. The training data comprises various data types like image, video, audio and text. For an AI-based model to understand the training data, the data must be accurately categorised and labelled or tagged. Like any other data type, even video data has to be annotated. Just like image annotation, the objective of video annotation is to enable AI models to recognize objects through computer vision.

A video is a logical sequence of images known as frames. In video annotation metadata, also called tags or labels, is added to the objects of interest in each frame of the video. The basic aim of video annotation is to make AI models detect the moving objects in the videos. This is done by frame-to-frame outlining of objects using various annotating techniques like 2D and 3D bounding boxes, polygons etc. Good quality of human-annotated video data sets can not only let companies improve their existing AI models but also design and produce remarkable AI applications.

Why Does it Make Sense to Outsource Your Video Annotation Projects?

It’s natural for organisations to go through the temptation of setting up onsite annotation services. The common reasoning is that the step will cut down on costs, save time and also maintain the security of their projects. But issues start flaring up soon, when their ML projects grow in scale and the companies experience distraction from their core business. That’s when the companies realise that it’s better to take the help of experts and outsource their annotation projects.

A professional video annotation company like SunTec.AI not only provides you with world-class annotations quality but our services come with a host of other benefits like:


SunTec.AI knows that for organisations, the security of their data is of utmost importance. To ensure complete safety of the data we have put in place multiple security measures. Our annotators work via VPN in a secure environment. SunTec.AI is ISO certified for data security so you can rest assured that your data is in safe hands.

Data Security by SunTec.AI


Irrespective of how sophisticated a computer vision model is, it will be rendered useless if it is trained on poor quality data. Quality of training data is very critical to the development of a world-class AI model. Outsourcing your data annotation project to a professional video annotation company ensures that your models are trained on quality data that is accurately categorised with extensive quality checks in place. SunTec.AI’s experienced and skilled professionals are adept at using annotation tools and other technologies required to annotate various data types accurately.

Time-bound Completion

Another big advantage you get by outsourcing annotation work to a professional annotation company is time-bound delivery of the project. While your own internal team tasked with annotation might not be able to finish the task due to its full-time obligations. A professional organisation, delivering annotation services will ensure time-bound completion of your project. SunTec.AI’s guidelines on work ethics ensure that speed and productivity of the professionals are not hampered and the project is delivered on time.

Have Diverse Requirements for Video Annotations? SunTec.AI Has It All Covered

Annotating videos to achieve high-quality datasets requires expertise and skill set and we at SunTec.AI are one of the leading video annotation services providers. Our experts will annotate the video footage and extract high-quality training data from them. These datasets can be used to train various AI and machine learning-based models. We offer various video annotation services ranging from Bounding Box annotation to Landmark annotation. With our video annotation services, you can focus on your project more rather than performing video annotation in-house, investing time and money.

Following are a few video annotation services for our customers:

Video Tagging using 2D and 3D Bounding Boxes Annotation

It is one of the most common types of video annotations used to train machines and enhance the search abilities of your Machine Learning models. Our video tagging specialists use 2D bounding box & 3D cuboid annotation techniques to mark the objects in the complex footage and create data sets used to train your computer vision.

Adapting to our client’s use cases or requirements, SunTec.AI employs the right set of annotation tools and expertise to annotate objects in a video using 2D or 3D annotation technique. Examples of use cases can be many like self-driving vehicles, drone/aerial navigation, objects/persons in an activity, movies or sports telecast. Using 2D and 3D bounding boxes video annotation techniques, accurate training data can be supplied to computer vision models which can help autonomous vehicles like cars recognize the various objects like signboards, pedestrians, other vehicles, traffic lights and signals, cyclists etc.

2D-3D Bounding boxes

Video Labeling using Polygons

Computer vision-based machines can not detect coarse and irregular-shaped objects on the street if there is no video labeling. And such challenges can be marked successfully using the Polygon Annotation technique. At SunTec.AI, we provide polygon annotation services to plot the points on the object vertices and determine its exact edges. Plotting the points helps the machines recognize the irregular and coarse-shaped objects in the footage.

Landmark Annotation

In Landmark annotation, annotators need to generate the dots for the images present in the video. After the dots are generated, the annotators build the structure of the required objects by connecting and linking the dots. Landmark annotation is used to identify and analyze even the minute details of human gestures and facial postures.

SunTec.AI’s Landmark video annotation services help prepare high quality, accurate training data for your computer vision models which helps it in accurately recognizing human emotions and expressions, activities, movements and different poses. Our reliable, efficient and state-of-the-art facility provides keypoint annotation over multiple frames for a range of applications. We ensure accurate tagging of structural points in frames of interest in your data.

Annotate Video with Semantic Segmentation

SunTec.AI offers pixel-based semantic segmentation of objects in each frame of a video. This technique is important when training data requires very fine granularity. We offer this pixel-wise annotation service to a wide range of industries. We ensure that our semantic annotation improves both product listings and customers’ access to the products. Our semantic annotation services help detect your AI model those individual parts and improve the overall quality of your model.

Video Annotation Process

We provide the best video annotation services to our customers. We have designed a professional video annotation process. Our professionals follow this standard procedure to extract quality datasets from the video footage. Following are the steps of the video annotation process that we follow at SunTec.AI

  • Connect With Experts

    Connect with our experts to share requirements with them. Our annotators work on the projects with a transformative and solution-based approach to achieve desired results. You can even connect with our experts while they are working on it to get insights of the progress.

  • Experts Annotate Videos

    Post understanding your project requirements, annotators will do a proper alignment of the video annotations tool and the processes involved in the technique. After the experts annotate the video and create high-quality datasets, they share the results with the QA team for the two-step quality check process.

  • Quality Check

    After the results are sent for evaluation to the QA team, the quality experts do the quality check. The quality check process verifies whether the data sets produced are 100% correct and meet the set standards. If datasets do not clear the quality check, they are sent for rework.

  • Project Delivery

    If the video annotation results are passed in the quality check, the project is then delivered to the customers. You can get the project delivered to you through multiple sources. You can either ask us to send the dataset to you as an email attachment or we can directly upload to the server.

  • Customer Feedback

    The customers can analyze whether the datasets achieved are as per their requirements. In case, customers are not satisfied with the results they can connect with our experts and ask for revisions. We serve our customers until they get the desired results.
