LCN Video Comparison: Multi-Video Synchronization Tool
What it is:
A web-based data analysis tool (version 1).
What we did:
- Develop a tool for data analysis
- Enable frame-by-frame navigation (1/30th second).
- Version 1 (for Version 2, please see: Infant Event Representations Heatmap Viewer)

13 April update: This project is now replaced by Analysis Tool
My lab partner, Yuexin Li, and I created (1) heatmaps that represent all participant gazepoints (2) a specialized data visualization website for the Language and Cognition Lab at Columbia University. The LCN Video Comparison Tool helps us compare multiple experimental videos simultaneously with frame-by-frame precision.
The tool solves a common research problem: comparing participants’ responses side by side. Frame-precise synchronization reveals subtle behavioral patterns that would otherwise remain hidden in sequential viewing.
Capabilities:
- Customizable grid layouts (1×1, 1×2, 2×2, 2×3)
- Synchronized playback of multiple videos
- Frame-by-frame navigation (1/30th of a second precision)
- Leader video designation that others follow
- Precise frame jumping/scrubbing across all videos
