 ## Dataset Structure
 
-This dataset uses the WebDataset format, storing samples in tar archives with JPEG-compressed images for efficient storage and streaming.
-
 ### Features
 
-Each sample in the tar archive contains:
-
-| File | Type | Description |
-|------|------|-------------|
-| `{id}.json` | JSON | Metadata: file, start, end, text, num_frames |
-| `{id}.pyd` | Pickle | List of JPEG-encoded frame bytes |
-
-### JSON Metadata Fields
-
-| Field | Type | Description |
-|-------|------|-------------|
+| Column | Type | Description |
+|--------|------|-------------|
 | `file` | string | Original video file path |
-| `start` | float | Start time of the sign segment (seconds) |
-| `end` | float | End time of the sign segment (seconds) |
+| `start` | float32 | Start time of the sign segment (seconds) |
+| `end` | float32 | End time of the sign segment (seconds) |
 | `text` | string | The English gloss/label for the sign |
-| `num_frames` | int | Number of frames in this sample |
+| `images` | list[Image] | Sequence of frames extracted from the video at 256x256 resolution |
