Datasets:
Potential action_log annotation/timestamp inconsistencies in VideoCUA: Joplin/51533 and Brackets/91222
Hi VideoCUA/GroundCUA team,
Thank you for releasing this dataset. While evaluating a video-only GUI trajectory extraction pipeline against VideoCUA, we manually inspected several disagreement cases and found two examples that may need annotation/timestamp verification in the original action_log.json.
I am reporting them here in case they indicate timestamp drift, missing intermediate actions, or action-log conversion ambiguity.
Case 1: Joplin / 51533
- Dataset path:
data/Joplin/51533/ - Video:
data/Joplin/51533/video/video.mp4 - Action log:
data/Joplin/51533/action_log.json - Task instruction:
Organize research topics in numbered bullet points in Joplin - Raw action index:
1 - Raw action type:
CLICK - Timestamp:
5.000s - Params:
{x: 515, y: 194, text: "Left", numClicks: 1} - Converted action:
left_click @ 5.000s
During manual visual inspection, this logged click appears inconsistent with the visible operation around that timestamp. A nearby detected click around 2.000s also appears to be a different operation rather than the same action with a shifted timestamp.
Could you please verify whether the CLICK @ 5.000s annotation is correct?
Case 2: Brackets / 91222
- Dataset path:
data/Brackets/91222/ - Video:
data/Brackets/91222/video/video.mp4 - Action log:
data/Brackets/91222/action_log.json - Task instruction:
Display the list of all available keyboard shortcuts from the help section. - Raw action index:
4 - Raw action type:
SCROLL - Timestamp:
11.928s - Params:
{scrollX: 1, scrollY: 10} - Converted action:
scroll down, amount=10 @ 11.928s - Cursor coordinate inherited from previous action in our conversion:
[383, 108]
During manual visual inspection, this logged scroll also appears inconsistent with the visible operation around that timestamp. The closest detected action around 9.000s is a left_click, which seems to be a different neighboring operation rather than the same action.
Could you please verify whether the SCROLL @ 11.928s annotation is correct?
Attached evidence
I attached marked contact sheets for both cases:
- Red marker: the original VideoCUA gold action timestamp/action.
- Blue marker: the nearest detected candidate from our video-only pipeline.
These examples are present in the final converted trajectory we used, but the source of the gold action is the original VideoCUA action_log.json.
Thanks again for the dataset. We are trying to use VideoCUA as a reference benchmark for video-to-GUI-trajectory extraction, so confirming these cases would help us understand whether they are annotation issues, timestamp alignment issues, or expected behavior.
