VFM / CAPABILITY SEQUENCE 01 / Compose

Task-level composition

ISpark Video
Fusion Model

One task. Specialized models. Local and global consistency.

System definition

VFM reads the task, assigns each span to the strongest generator, aligns neighboring spans locally, then checks the full sequence globally.

Temporal completion

Fill the missing time. Keep the observed anchors.

Start with 5 seconds. VFM keeps 5 observable anchors, fills the 10 missing positions, checks continuity, and returns one 15-second sequence.

Output refinement

Refine spatial detail and motion continuity.

Once the sequence exists, VFM can refine spatial detail and motion continuity. These studies show the same task from two measurable views.
