| # FineMotion-Style |
|
|
| FineMotion-Style accompanies *Learning Kinematic Frequency-Aware Disentanglement |
| for Motion Style Transfer and Editing*, SIGGRAPH Asia 2026. The integrated |
| research corpus uses six sources. This Hugging Face Dataset contains |
| the two **Bandai motion/text and BVH companion archives**. Frozen protocol IDs |
| are already included in the GitHub code repository. Other sources are acquired |
| from their official providers and processed locally. |

|
| ## Downloads |
|
|
| The selected components and their SHA256 values are recorded in the |
| [archive manifest](https://github.com/dongran/finemotion-style/blob/main/release_metadata/release_archives.json). |
|
|
| - [Bandai original v1 — motion, features and text](https://huggingface.co/datasets/randong/FineMotion-Style/resolve/main/finemotion_bandai_original_v1_20261016_en.tar.gz?download=true): 3,077 archived SMPL24 source sequences, 2,676 paired |
| 20Hz HumanML263 feature/text clips, source mappings, split projections and |
| a complete BVH-to-MotionBuilder-to-SMPL example. The archived source sequences |
| use 30Hz; another project can choose a different conversion rate. |
| - [Bandai BVH companion — native and SMPL-derived views](https://huggingface.co/datasets/randong/FineMotion-Style/resolve/main/finemotion_bandai_bvh_companion_v1_20261016_en.tar.gz?download=true): 3,077 original animation BVH files and 3,077 matching |
| SMPL-derived BVH exports, with explicit stage labels and source/clip mapping. |
| These later SMPL-derived exports are not the original MotionBuilder output. |
|
|
| These two Bandai archives provide different representations of the same source |
| collection; they do not reconstruct the full six-source research corpus. The |
| previously prepared three-source text archive is not selected for this initial |
| Hugging Face release. |
|
|
| ## Frozen protocol IDs on GitHub |
|
|
| The 292 original split/benchmark ID lists are available in the code repository: |
| [download the frozen protocol archive](https://github.com/dongran/finemotion-style/raw/refs/heads/main/protocols/finemotion_frozen_protocol_v1_20261016.tar.gz) |
| and read its [package guide and checksum instructions](https://github.com/dongran/finemotion-style/blob/main/protocols/README.md). |
| The file is 7,944,168 bytes, with SHA256 |
| `3209df832ac2729e30c1544bf1eb56e954179f4033efeb71a7588b27b4bd1a49`. |
| This GitHub package contains frozen memberships and package metadata, with no |
| source captions, motions or model weights. Its IDs refer to all six sources; |
| the protocol archive is supplied through GitHub separately from the two Hugging |
| Face data downloads. |
|
|
| ## Acquiring the other sources |
|
|
| - [HumanML3D](https://github.com/EricGuo5513/HumanML3D), with |
| [AMASS](https://amass.is.tue.mpg.de/) where original motion parameters are needed. |
| - [Motion-X](https://github.com/IDEA-Research/Motion-X). |
| - [LAFAN1](https://github.com/ubisoft/ubisoft-laforge-animation-dataset). |
| - [Motorica Dance Dataset](https://github.com/simonalexanderson/MotoricaDanceDataset). |
| - [FineDance](https://github.com/li-ronghui/FineDance). |
|
|
| Obtain each dataset, labels and required model assets under its provider's terms. |
| The repository documents source conversion, ID/crop mappings, video descriptions, |
| HumanML-format text, lemma/POS and benchmark rules. Historical code and recovered |
| settings are distinguished from fresh end-to-end verification in the |
| [source guide](https://github.com/dongran/finemotion-style/blob/main/docs/SOURCE_RECONSTRUCTION.md). |
|
|
| ## Text, time tags and frozen IDs |
|
|
| HumanML3D and Motion-X use their inherited annotation routes. For the four newly |
| annotated sources, historical MAIN descriptions commonly use source labels and |
| DETAILS were generated with VideoLLaMA3. The text format is: |
|
|
| ```text |
| caption#lemma/POS lemma/POS ...#start_seconds#end_seconds |
| ``` |
|
|
| The two caption lines are alternatives for the same motion; `0#0` denotes the |
| whole paired clip. POS tags describe words, not the four benchmark families. |
|
|
| Regenerating descriptions with a VLM need not reproduce the old wording or |
| POS tokens. Keep a separately named text version while retaining the historical |
| clip IDs, train/validation/test partitions and benchmark lists. Missing source |
| files must be reported rather than filled with new IDs. Reclassifying revised |
| captions defines a new benchmark version, not the frozen paper protocol. |
|
|
| The saved motion-availability pool has 59,038 IDs; the paper's 59,039 count has |
| an unresolved one-ID discrepancy. The 67,907-ID base text/feature pool and its |
| 13,357 strict style labels have different scopes. See the |
| [benchmark protocol](https://github.com/dongran/finemotion-style/blob/main/docs/BENCHMARK_PROTOCOL.md). |
|
|
| ## Provenance, limitations and licences |
|
|
| Bandai data and annotations are distributed under **CC BY-NC 4.0**, with source |
| attribution, original notices and the transformation history in the archive. |
| The source creator is Bandai Namco Research Inc. The conversion uses |
| [our 2025 processing method](https://github.com/dongran/tempo-changing-music2motion). |
| Project code, documentation and the protocol-ID material on GitHub retain their |
| MIT notices; the card's data-licence tag does not replace component-specific terms. |
| SMPL-Body rig attribution in the BVH view retains its separate CC BY 4.0 terms. |
|
|
| SMPL model weights, blend shapes and characterized target templates are obtained |
| separately. Other providers' motions and full annotation corpora are not included. |
| No source creator endorses this adaptation. See the |
| [source notices](https://github.com/dongran/finemotion-style/blob/main/NOTICE.md). |
|
|
| The original annotations are preserved; Qwen revision proposals are not applied |
| automatically. The four-source first-pass review completed on 2026-10-16, but |
| model flags are not ground-truth accuracy measurements. The selected October 16 |
| Bandai packaging revision translates comments and removes absolute preparation |
| paths while preserving all motion, feature, caption and split bytes from the |
| October 14 archive. Current findings and bounded known issues are in the |
| [release guide](https://github.com/dongran/finemotion-style/blob/main/docs/RELEASE_V1.md). |
|
|
| Preserve an immutable original-v1 revision. Publish later accepted caption or |
| conversion changes as separately identified versions with old/new hashes and |
| change ledgers. A different text version does not silently replace frozen IDs. |
