The Label Studio 1.6 open-source release now supports video object tracking in general availability, making it a popular open-source data labeling platform to support all data types—video, image, text and hypertext, time-series and audio. In addition to the new video player that supports frame-by-frame video object tracking, the latest release also features a new annotation user interface (UI) that is more efficient, ergonomic and flexible.

Video Classification was available prior to version 1.6, but the latest release introduces a new video player and enables Video Object Tracking, giving users the ability to: label and track objects across subsequent frames, for fine-grained control; use optional hotkey-driven navigation for even greater granularity in tracking objects; add keyframes and automatically interpolate bounding boxes between keyframes to easily transition bounding box sizes and positions; and select and label between timestamps on the video with improved timeline segmentation.

The major update to the annotation UI in the 1.6 release supports the new video player, but benefits labeling workflows for every data type. New functionality includes: Dual ‘Region’ and ‘Details’ control panels vs. a single sidebar, allowing annotators to view all pertinent information about the task without scrolling; collapsable, draggable and resize-able panels for annotators to customize their workspace; more granular controls for each bounding box; and also, a cleaner interface to group, organize regions, link, add metadata and delete regions, plus new functionality to lock regions.
