# Route Red-Yellow Vector Split-Subtask Example
This is a LeRobot v2.1 example derived from
[ajaysri/route_red_yellow_vector_subtasks_pi05](https://huggingface.co/datasets/ajaysri/route_red_yellow_vector_subtasks_pi05).
Source episode(s) 2 are split into one output episode per maximal
contiguous run of `metadata.route.active_subgoal`.
The example has 4 output episodes and 948 frames.
All three videos are cut on the same frame boundaries as the Parquet data and
re-encoded as H.264 at 100 Hz.
## Why the split count is inferred
The complete 212-episode source dataset contains suffixes of the four-phase
route task:
- four segments: 52 episodes
- three segments: 51 episodes
- two segments: 53 episodes
- one segment: 56 episodes
No repeated or backward transitions were found. The builder therefore detects
boundaries from the frame labels instead of assuming four subtasks.
## Provenance
Every frame includes:
- `metadata.split.source_episode_index`
- `metadata.split.source_frame_index`
- `metadata.split.source_start_frame`
- `metadata.split.source_end_frame_exclusive`
- `metadata.split.segment_ordinal`
The original visual conditioning, prompts, actions, states, and route metadata
are retained. `frame_index`, `episode_index`, `index`, and `timestamp` are
reindexed for the split dataset.
