# Molmo2-VideoTrack

Molmo2-VideoTrack is a dataset of video point tracking annotations collected from human annotators across 16 video datasets.
It can be used to fine-tune vision-language models for video object tracking via point trajectories.

Molmo2-VideoTrack is part of the [Molmo2 dataset collection](https://huggingface.co/collections/allenai/molmo2-data) and was used to train the [Molmo2 family of models](https://huggingface.co/collections/allenai/molmo2).

## Usage
```python
from datasets import load_dataset

# Load entire dataset
ds = load_dataset("allenai/Molmo2-VideoTrack", split="train")

# Filter by video dataset
dancetrack = ds.filter(lambda x: x == 'dancetrack', input_columns='video_dataset')
```

## Data Format

Each row contains tracking annotations for one or more objects in a video clip:

| Field | Description |
|-------|-------------|
| `id` | Unique identifier for this annotation |
| `video` | Video filename |
| `clip` | trimmed clip id |
| `video_dataset` | Source dataset name (e.g., 'dancetrack', 'mose') |
| `video_source` | Video directory used in training (can be ignored) |
| `exp` | Text expression describing the tracked object(s) |
| `obj_id` | List of object IDs per video |
| `mask_id` | List of mask IDs corresponding to tracked objects starting from '0' |
| `points` | List of point trajectories per object. Each entry contains `object_id` (corresponding to an ID in `mask_id`) and `points` (list of [x, y] coordinates per frame). Example: `[{'object_id': '0', 'points': [[x1, y1], [x2, y2], ...]}, ...]` |
| `segments` | List of segment annotations per object. Each entry contains `object_id` (corresponding to an ID in `mask_id`) and `segments`. Example: `[{'object_id': '0', 'segments': [...]}, ...]` |
| `start_frame` | Starting frame index for this clip (use to trim the source video) |
| `end_frame` | Ending frame index for this clip (use to trim the source video) |
| `w` | Video width |
| `h` | Video height |
| `n_frames` | Number of frames in the clip |
| `fps` | Used in training |

**Important:** `start_frame` and `end_frame` indicate which portion of the source video to use. You need to trim the video to this range — the annotations correspond to frames within `[start_frame, end_frame]`, not the entire video.
