Annotation Tool

High-speed video labeling to expedite AI/ML model development with quality and efficiency

Video annotation tool powered by the iMerit Ango Hub drastically reduces the time required for annotating videos, especially when dealing with a substantial number of labels. Reviewing annotated tasks becomes a breeze, thanks to our intuitive interface that offers a comprehensive overview of annotations, allowing reviewers to quickly assess and verify details directly from the timeline.

Annotate Any Format

What truly sets us apart is our robust support for various video formats and capability to handle large volume of annotations at a time. This flexibility is a step up from traditional annotation tools, particularly in sectors like automotive and healthcare.

  • Supporting formats like .mp4, .mov, .webm, .ogg and multi-frame DICOM .dcm files
  • Accommodates videos up to 1 hour in duration at a time with resolution up to 2k
  • Labeling tools supported include Bounding Box, Rotated Bounding Box, Polygon, Polyline, Segmentation, Point and Brush

Timeline View

Opening a video file or a multi-frame DICOM file in the iMerit Ango Hub will open a timeline view of annotations on the video. This feature extends to frame-specific classifications, where annotators can classify individual frames in the video. 

  • See the annotations throughout the video visually.
  • Users can easily add or delete keyframes and have better control over their video annotations.

Frame Interpolation

Now, users can draw a polygon or a segmentation in one frame and move it forward any number of frames. Annotators can edit these polygons or segmentations at any point in a video, and iMerit Ango Hub will automatically interpolate them accordingly.


The need for speed in high-quality data annotation has never been greater. iMerit combines the best of predictive and automated annotation technology with world-class data annotation and subject matter experts to deliver the data you need to get to production, fast.
