Behavior Annotators

Browser-based tools for scoring behaviors frame by frame, each tailored to a specific project's ethogram.

General · Single Animal
Behavioral Annotator

A browser-based GUI for annotating animal behaviors in videos, frame by frame, built to power our Animal Behavioral Dataset effort.

Can Tao By Dr. Can Tao
Social Interaction · 4 Tracks

Audio & Video

Tools for working with vocalizations and multi-stream recordings alongside behavior.

Audio · Vocalization
USV Call Annotator

Load a recording, view its spectrogram, and mark ultrasonic vocalization calls as time–frequency boxes with labels, then export the annotations.

By Arjun Kode
Audio · Video Sync
Audio–Video Synchronizer

Align audio recordings with their video streams so vocalizations and behavior can be reviewed on a common timeline.

By Jihyo Lee
Video · Cropping & Trimming
ROI Clipper

Load a video, draw regions of interest to crop, and trim in time to the segments you need, then export the clips right in the browser. It also generates a ready-to-run ffmpeg batch script you can copy and paste to crop and trim every clip at once locally, for a lossless re-encode on any machine with ffmpeg installed.
