MUGen-VR-AnyFlow-Conditioner

MUGen-VR AnyFlow Conditioner

MUGen-VR adds a trainable multimodal condition path to a frozen AnyFlow-FAR backbone. ImageBind encodes text, image, and audio inputs; InternVideo2 encodes videos and retrieved references. Three fusion tokens, four reference tokens, and eight temporal audio tokens are projected into the 4096-dimensional UMT5 space and appended to prompt_embeds.

Files

The release contains only project-owned lightweight artifacts:

• Fusion, Reference Adapter, condition projector, and modality/type embeddings.
• Sharded safetensors weights with a standard tensor-to-shard index.
• Sanitized training configuration, evaluation metadata, and checksums.

It excludes AnyFlow, ImageBind, and InternVideo2 weights, MSR-VTT media, cached features, and optimizer state. These dependencies must be obtained under their upstream terms.

Targeted Consistency Evaluation

The fixed evaluation uses 40 held-out samples with generation seed 42. Condition scale 0.05 was selected on a separate validation split.

MUGen-VR reduces subject-consistency error by 2.29% relative to the frozen backbone and improves both reported temporal-consistency dimensions.

Scope

• AnyFlow is restricted to non-commercial use under NVIDIA NSCLv1.
• ImageBind is governed by non-commercial research terms.
• Audio conditions influence video tokens but do not create an output soundtrack.
• Retrieval requires a separately licensed reference gallery.
• Results are specific to the released checkpoint and evaluation subset.
