Overview

VideoCUA is the largest open expert video corpus for desktop computer use, comprising ~10K tasks, 55 hours of continuous 30 fps screen recordings, and 6 million frames across 87 professional desktop applications spanning 12 categories.

Unlike sparse screenshot datasets, VideoCUA preserves the full temporal dynamics of human interaction — every mouse movement, click, drag, scroll, and keystroke is logged with millisecond precision alongside continuous video. This enables research in action prediction, imitation learning, visual world models, and video-based reward modeling.

VideoCUA is part of CUA-Suite, a unified ecosystem that also includes:

• UI-Vision — A rigorous desktop-centric benchmark evaluating element grounding, layout understanding, and action prediction.
• GroundCUA — A large-scale pixel-precise UI grounding dataset with 5M+ human-verified element annotations.

Data Format

Each application zip in raw_data/ contains multiple task folders identified by numeric task IDs. Each task folder has the following structure:

<task_id>/
├── action_log.json          # Task metadata and timestamped actions
└── video/
    ├── video.mp4            # Continuous 30 fps screen recording (1920×1080)
    └── video_metadata.json  # Video properties (fps, duration, resolution, etc.)

action_log.json

{
  "task_id": 45525,
  "task_instruction": "Open test.7z present in archive it and see the contents",
  "platform": "7-Zip",
  "action_log": [
    {
      "action_type": "CLICK",
      "timestamp": 2.581,
      "action_params": {
        "x": 47,
        "y": 242,
        "numClicks": 2
      },
      "groundcua_id": "9a7daeed..."
    }
  ]
}

Each action entry includes a groundcua_id field — this is the unique identifier for the corresponding screenshot in the GroundCUA repository. Using this ID, you can look up the fully annotated screenshot (with pixel-precise bounding boxes, textual labels, and semantic categories for every visible UI element) in GroundCUA, linking the video action trajectory to dense UI grounding annotations.
