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.
Hi Tianjun,
Thanks for the comment. I did not see your attachment, but we will look into the case. Will get back to you asap! (If you want to send me more evidence to help me locate the problem, please send it to x2jian@uwaterloo.ca, thx!)
