IDM Eval Set
A validation set for evaluating Inverse Dynamics Models on macOS screen recordings. Each sample is a 5-second clip of real desktop usage (browser, IDE, terminal) paired with a ground-truth action log captured at the OS level.
The task: given a short screen recording, predict the sequence of user input actions (keypresses, mouse clicks, scrolls) that produced the observed screen changes.
Dataset Structure
clips_recording_{uuid}_seg{N}/
clip_000_{tag}.mp4 # 5s screen recording (1728x1080)
clip_000_{tag}.json # ground truth action log
editing-work/
input_{uuid}_seg{N}.msgpack # raw input event streams
recording_{uuid}_seg{N}.mp4 # full source recordings
Stats
| Clips | 51 |
| Recordings | 11 |
| Total raw actions | 10,914 |
| Resolution | 1728 x 1080 |
| Clip duration | 5 seconds |
Tag distribution:
| Tag | Count |
|---|---|
| scroll/drag | 18 |
| keystroke-heavy | 17 |
| mixed | 4 |
| click-heavy | 4 |
| hotkeys | 2 |
| hard-case | 1 |
Action Log Format
Each clip JSON contains:
{
"start_s": 206.913,
"end_s": 211.913,
"tag": "keystroke-heavy",
"actions": [
[206933331, ["KeyPress", [32, "Space"]]],
[207233331, ["KeyRelease", [32, "Space"]]],
[208633331, ["MousePress", ["Left", 0, 0]]],
[209533331, ["MouseScroll", [0, -1, 0, 0]]]
]
}
- Timestamps are absolute microseconds (subtract
start_s * 1e6for clip-relative) - Action types:
KeyPress,KeyRelease,MousePress,MouseRelease,MouseMove,MouseScroll,ContextChanged - KeyPress params:
[keycode, key_name] - MousePress params:
[button, x, y](coordinates not captured in this version) - MouseScroll params:
[dx, dy, x, y]
Annotations
annotations.json contains manual visibility labels for each primary action (KeyPress, MousePress, MouseScroll) in each clip. Keys are clip paths, values map action indices to one of three labels:
| Label | Count | Meaning |
|---|---|---|
visible |
510 | Effect is directly visible in the frames |
inferable |
266 | Effect can be inferred but isn't directly visible |
not_predictable |
34 | Cannot be predicted from video alone |
{
"clips_recording_.../clip_003_keystroke-heavy": {
"0": "visible",
"1": "inferable",
"2": "not_predictable"
}
}
Use these to filter ground truth when scoring — e.g. exclude not_predictable actions from recall calculations.
